A nursing home is installing their own bulk oxygen system due to their large volume of consumption. OSHA regulation 29 CFR 1910.104(b)(2)(iii) requires owners of bulk oxygen systems to provide noncombustible surfacing in areas where liquid oxygen might leak during operation of the system or during the filling of a storage container. If the nursing home provides an asphalt surface in areas where oxygen could potentially leak, will it be in compliance with the workplace regulation regarding oxygen? Explain your answer
Answer:
NO! It would be in violation of the workplace regulation regarding oxygen.
Explanation:
Bulk oxygen systems convey liquified oxygen which is of geat use and importance in institutions like a nuirsing home.
Liquified oxygen is gaseos oxygen that has been condensed under high presures into liquid form. It is transported via a complex system of vaporizers, storage tanks and pipes around the facility it is needed. Liquified oxygen is oxygen- rich.
Asphalt is a petroleum derivative that is often used to in coating surfaces and tarring roads.
Its primry constituent is Carbon with minor constitunets like sulphur, nirogen, oxygen. As a petrolem derivative, it is very combustible.
In the event of an oxygen leak on an asphalt surtface, oxygen acting as an oxidizing agent can combine with asphalt in the presence of air, to cause a large fire.
Hence, asphalt surfacing in areas of oxygen leaks, would not be in compliance with the workplace regulation as it has the potential of causing a fire in the nursing home.

The electron configurations of two unknown elements x and y are shown. X: 1s2 2s2 2p6 Y: 1s2 2s2 2p6 3s2 3p6 Which statement is most likely correct about the two elements? A) They will react because X can give up two electrons B) They will react because X and Y can share two pairs of electrons to become stable C) They will not react because both have a complete outermost shell and are stable D) They will not react because both will give up one electron. to become stable.
Answer:
B) They will react because X and Y can share two pairs of electrons to become stable
Explanation:
The electron configurations of two elements x and y are given :
X: 1s2 2s2 2p6
Y: 1s2 2s2 2p6 3s2 3p6
The statement that is true for both the elements is that, they both will react as they both can share two pairs of electrons to become stable.
To become stable the outermost shell or p orbital should have 8 electrons, so element X can gain 2 atoms to become stable.
Element Y can also react as it can also share two atoms to fulfill its 3p orbital and will stable.
Hence, the correct option is "B".
Adding a base to a solution would...?
Answer:
it would decrease [h+]
Explanation:
This is due to neutralization If a base is added to an acidic solution, the solution becomes less acidic and its position changes to the middle of the pH scale.
hope this helps
Answer:
Raise the pH
decrease [H+]
Explanation:
=> Adding base would raise the pH (Bases have more pH and Acids have less pH)
=> Adding base would decrease the concentration of [H+] ions as it contains hydroxyl ions which neutralized with H+ ions so as a result the concentration of [H+] ions decreases.

Explanation:
g When a 2.75g sample of liquid octane (C8H18) is burned in a bomb calorimeter, the temperature of the calorimeter rises from 22.0 °C to 41.5 °C. The heat capacity of the calorimeter, measured in a separate experiment, is 6.18 kJ/°C. Determine the ΔE for octane combustion in units of kJ/mol octane.
Answer:
The correct answer is 5021.25 kJ/mol octane
Explanation:
The heat absorbed by the calorimeter is given by:
heat absorbed = Ccal x ΔT
Given:
Ccal = 6.18 kJ/ºC (heat capacity of calorimeter)
ΔT= Final temperature - initial temperature = 41.5ºC-22.0ºC = 19.5ºC
We first calculate the heat absorbed:
heat absorbed = 6.18 kJ/ºC x 19.5ºC = 120.51 kJ
The change in internal energy (ΔE) is equal to the heat absorbed by the calorimeter. In order to determine ΔE in kJ/mol we have to divide the heat into the number of moles of octane (C₈H₁₈) burned in the calorimeter.
Molecular weight (C₈H₁₈) = (12 g/mol x 8) + (1 g/mol x 18) = 114 g/mol
Moles of C₈H₁₈= mass/molecular weight= (2.75 g)/(114 g/mol)= 0.024 moles
Finally, we calculate ΔE:
ΔE = heat absorbed/moles of octane = (120.51 kJ)/(0.024 mol octane) = 5021.25 kJ/mol octane
What is the [H+] in a solution with pOH of 0.253? A. 5.58 × 10−15 M B. 1.79 × 10−14 M C. 3.21 × 10−2 M D. 5.58 × 10−1 M
Answer:
The answer is option BExplanation:
To find [H+] in the solution we must first find the pH
That's
pH = - log[H+]
pH + pOH = 14
pOH = 0.253
pH = 14 - 0.253
pH = 13.747
Since we've found the pH we can now find the [H+] in the solution
We have
pH = - log[H+]
13.747 = - log[H+]
Take antilog of both sides
We have the final answer as
[tex][H+] = 1.79 \times {10}^{ - 14} M[/tex]
Hope this helps you
Answer:
Okay so we know that pOH + pH = 14, so if pOH is 0.253 the pH would be 13.747.
And pH = -log [H+], so [H+] = 10^(-pH) -->This is just the antillog...
so [H+] = 1.791e-14, which would make sense for the strongly basic solution (so B is the correct answer)
Hope this helps...
Suppose a 22.092 g sample of a 1:1 mixture of acetylferrocene and ferrocene was separated by column chromatography, and the recovered fractions weighed 9.017 g (acetylferrocene) and 8.075 g (ferrocene), what was the percent recovery of acetylferrocene?
Answer:
81.6%
Explanation:
mass of acetylferrocene and ferrocene mixture = 22.092 g
mass ratio acetylferrocene and ferrocene mixture = 1 : 1
The sum of the ratios = 2, therefore the mass of each compound will be half the mass of the mixture
mass of each compound in the sample mixture = 1/2 * 22.09 2= 11.046 g
mass of recovered acetylferrocene = 9.017 g
percentage recovery = mass recovered/mass in sample * 100%
percentage recovery of acetylferrocene = (9.017 g / 11.046 g) * 100%
percentage recovery of acetylferrocene = 81.6%

O A. Convergent boundaries
B. Reverse faults
c. Divergent boundaries
O D. Normal faults
Answer:
The correct options are;
C. Divergent plate boundary
D. Normal faults
Explanation:
Tensile stress tends to pull objects part by acting axially upon the object to pull the object on a cross section perpendicular to the objects cross-section
The most common stress in convergent plate boundaries is compression stress
The most common stress in divergent plate boundaries is tensile stress
In the presence of tensile stress, normal faults results in the raising of mountains due to their enormous forces
Therefore, the features of Earth's crust involving tension are divergent plate boundary and normal faults.

Choose all of the orbitals that can form a σ bond to the orbital displayed below (side-by-side, in the orientation shown).
Answer:
s orbital
Explanation:
The orbital shown is a py orbital. py orbitals overlap side by side with s orbital to form a sigma bond. Looking at the direction of the Px and py orbitals, overlap of these with a py orbital can only lead to the formation of a pi bond.
However, the s orbital being spherically symmetric overlaps with py orbital in such a manner that a sigma bond is formed. The s orbital overlaps with one of the lobes of the py orbital.
Sigma bonds are formed by end to end overlap of atomic orbitals. It is the strongest type of covalent bond.

How is the atomic number related to core electrons?
O A. The atomic number is equal to the number of core electrons.
O B. The atomic number minus the period number is the number of
core electrons.
O C. The atomic number plus the group number is the number of core
electrons.
O D. The number of valence electrons plus core electrons is the atomic
number
Answer:
D
Explanation:
If the atom is neutral, the sum of the core and valence electrons is the same as the number of protons, which is the atomic number of the element. So if the sum of the core and valence electrons in a neutral atom equals 25 , that is the number of protons in the atomic nucleus, and the atomic number of the element.
The number of valence electrons plus core electrons is the atomic number.

A tank originally had 12.0 atm, was 3.9L at 25C. If the tank is heated to 591C what is the new pressure ?
Answer:
34.79 atm.
Explanation:
The following data were obtained from the question:
Initial pressure (P1) = 12 atm
Initial temperature (T1) = 25 °C
Final temperature (T2) = 591 °C
Final pressure (P2) =...?
Note: the volume of the tank is constant.
Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:
Temperature (K) = Temperature (°C) + 273
T(K) = T (°C) + 273
Initial temperature (T1) = 25 °C
Initial temperature (T1) = 25 °C + 273 = 298 K.
Final temperature (T2) = 591 °C
Final temperature (T2) = 591 °C + 273 = 864 K.
Finally, we shall determine the new pressure as follow:
Initial pressure (P1) = 12 atm
Initial temperature (T1) = 298 K.
Final temperature (T2) = 864 K.
Final pressure (P2) =...?
P1/T1 = P2/T2
12/298 = P2/864
Cross multiply
298 x P2 = 12 x 864
Divide both side by 298
P2 = (12 x 864)/298
P2 = 34.79 atm.
Therefore, the new pressure is 34.79 atm.

In this titration, solution P (that contains hydrochloric acid) is added into the conical flask that contains sodium hydroxide drop by drop. The indicator (phenolphthalein) changes color when all the NaOH is completely neutralized.
i) Solution P contains hydrochloric acid. Hydrochloric acid is the chemical that reacts with sodium hydroxide to give salt and water.
This type of reaction is called neutralization.
ii) Under alkaline conditions, phenolphthalein appears pink in color. When the solution becomes neutral or acidic, it is colorless.
So, the color change of the mixture at the end point is from pink to colorless.
iii) same explanation from question i,
HCl (aq) + NaOH (aq) --> NaCl (aq) + H2O (l)
iv) no. of moles = volume (in dm3) x concentration
hence,
no. of moles of NaOH used = 25/1000 x 0.1
= 0.0025 mol
From the equation in (iii), since the mole ratio of HCl : NaOH = 1:1, meaning 1 mole of HCl reacts completely with 1 mole of NaOH.
This also means that the no. of moles of NaOH reacted equals to the no. of moles of HCl needed to react with it, which is 0.0025 mol.
Given the concentration of HCl in solution P is 0.1 mol /dm3. (pls correct me if I misunderstood your comment),
if v is the volume of HCl needed,
0.0025 = 0.1 v

May I know how to balance this
Answer:
C₅H₁₂ + 8O₂ → 5CO₂ + 6H₂O
Explanation:
Let's start by counting how many molecules we have on each side.
Reactants
C - 5
H - 12
O - 2
Products
C - 1
O - 3
H - 2
We have to balance both sides. Since we have 5 carbon atoms on the reactants side and 1 carbon atom on the products side, we'll start with that. Write 5 as the coefficient for CO₂ to balance the carbons.
C₅H₁₂ + O₂ → 5CO₂ + H₂O
Now that the carbons are balanced, let's look at the hydrogens. There's 12 on the reactants side and 2 on the products side. To balance the hydrogens, we have to write 6 as the coefficient for H₂O.
C₅H₁₂ + O₂ → 5CO₂ + 6H₂O
Now the hydrogens are balanced. All that's left to do is balance the oxygens. Let's start by counting how many atoms we have on each side.
Reactants
C - 5
H - 12
O - 2
Products
C - 5
H - 12
O - 16
So, to balance the number of atoms on both sides, write 8 as the coefficient for O₂.
C₅H₁₂ + 8O₂ → 5CO₂ + 6H₂O
Lastly, let's check to make sure everything is balanced.
Reactants
C - 5
H - 12
O - 16
Products
C - 5
O - 16
H - 12
Both sides are balanced. Therefore, the balanced chemical equation is: C₅H₁₂ + 8O₂ → 5CO₂ + 6H₂O.
Hope that helps.
Answer:
[tex]\boxed{C_{5}H_{12} + 8O_{2} -->5CO_{2} + 6H_{2}O}[/tex]
Explanation:
Part 1: Count the number of atoms on each side per element
To start, count the number of atoms per element on both sides of the equation.
Left Side
C - 5 atoms
H - 12 atoms
O - 2 atoms
Right Side
C - 1 atom
H - 2 atoms
O - 3 atoms
Part 2: Balance carbon atoms
Now, with this information, you can begin finding out how to properly balance both sides of the equation.
You need 5 carbon atoms on the left, so place a coefficient of 5 in front of the [tex]CO_{2}[/tex] product. This will balance the carbons. Do not place a coefficient in front of the [tex]C_{5}H_{12}[/tex] reactant - none are necessary!
Then, you can update your counts for your atoms.
Left Side
C - 5 atoms
H - 12 atoms
O - 2 atoms
Right Side
C - 5 atoms
H - 2 atoms
O - 11 atoms
The updated equation will look like this:
[tex]\boxed{C_{5}H_{12}+O_{2} --> 5CO_{2} + H_{2}O}[/tex]
Part 3: Balance hydrogen atoms
Now, balance the hydrogen atoms. Place a coefficient of 6 in front of the [tex]H_{2}O[/tex] product. This will balance the hydrogen atoms.
Once again, update the atom counts:
Left Side
C - 5 atoms
H - 12 atoms
O - 2 atoms
Right Side
C - 5 atoms
H - 12 atoms
O - 16 atoms
The updated equation will look like this:
[tex]\boxed{C_{5}H_{12} +O_{2}--> 5CO_{2} +6H_{2}O}[/tex]
Part 4: Balance oxygen atoms
To fully balance the equation, place a coefficient of 8 in front of the [tex]O_{2}[/tex] reactant. This will equalize the amount of oxygen atoms on both sides of the equation.
The updated equation will look like this:
[tex]\boxed{C_{5}H_{12} + 8O_{2} --> 5CO_{2} + 6H_{2}O}[/tex]
Part 5: Check the equation and atom counts
Now, update the atom counts one last time to make sure they are equal.
Left Side
C - 5 atoms
H - 12 atoms
O - 16 atoms
Right Side
C - 5 atoms
H - 12 atoms
O - 6 atoms
They are equal, so you may proceed.
Part 6: Check if reductions are necessary
If the equations coefficients can all be divided by a common divisor (i.e., 3), follow up with that step. However, any equation that has a reactant or product without a coefficient, skip this step entirely.
This equation falls into that category, so you may proceed past it.
Your final equation will look like this: [tex]\boxed{C_{5}H_{12} + 8O_{2} -->5CO_{2} + 6H_{2}O}[/tex]
