Answer:

whats CH3COOH please tell me so I can answer!

Answer:

A. CO

Explanation:

This is the answer I believe based on that it has the least amount of elements leading me to think that it would have the least ionic character.

The compound that contains a bond with the least ionic character is CO.

Ionic bonding involves transfer of valency electrons. Usually from a metal to a non metal.

The ionic character or nature of a bond is determined by the relative

electronegativity of the atoms involved.

So, the bigger the difference between the electronegativity of two atoms, the more likely it is to be ionic.

This simply implies that if the electronegativity differences of the atoms

involved are smaller, the ionic character will be small.

Therefore, the  compound that contain a bond with the least ionic character is CO.

The difference in negativity of the carbon and oxygen atoms are small, this is

why the compound CO among the options possess the least ionic character.

Answer:

e. None of these.

Explanation:

Hey there!

In this case, since the Henry's law is defined in terms of pressure, henry's constant and pressure, as shown below:

[tex]C=K_H*P[/tex]

Whereas C is the concentration, KH the Henry's constant and P the pressure, we infer that the concentration of a gas solution is directly proportional to the pressure, which is not the group choices, therefore, the answer is e. None of these.

Hi how are you doing today Jasmine

Answer:

0.04 L (or 40 mL)

Explanation:

The dilution equation is: [tex]M_{s} V_{s} = M_{d} V_{d}[/tex]

[tex]M_{s}[/tex] = the molarity of the sock solution

[tex]V_{s}[/tex] = the volume of the sock solution

[tex]M_{d}[/tex] = the molarity of the diluted solution

[tex]V_{d}[/tex] = the volume of the diluted solution  

We are given the original, or stock, solution, which is [tex]M_{s} = 7.00 M NaOH[/tex], and [tex]V_{s} = 0.02 L (20 mL)[/tex]. We are also given the final molarity, which is: [tex]M_{d} = 3.5 M NaOH[/tex].

So, plugging our given into the dilution equation, results in:  

[tex]7.00 M * 0.02 L = 3.5M * V_{d}[/tex] (divide both sides by 3.5 M, in order to get [tex]V_{d}[/tex] by itself).

[tex]\frac{7.00 M * 0.02 L}{3.5M} = V_{d}[/tex]

[tex]V_{d} = 0.04 L (or 40 mL)[/tex]

So, the final volume of a 3.5 M NaOH solution, with an original solution of 20 mL of a 7.00 M NaOH solution, is 0.04 L (or 40 mL)

Hopefully this helped. Good luck!

Explanation:

The graphic is the heating curve for water. Note that it is divided into 5 distinct heat flow segments. The segments with changing slopes are single phase segments with changes in temperature values. From left to right segment A is solid ice being warmed to it's melting point. Segment B is the melting segment in which 2 phases are in contact (solid + liquid). Note that addition of heat does not change the temperature. Segment C is warming of the liquid (single phase) up to its boiling point. At the boiling point the liquid begins to pass into the gas phase and again 2 phases are in contact; i.e., liquid & gas. Note again when two phases are in contact no temperature change occurs. Finally, segment E is the heating of the pure, single phase gas.

In summary ...

Segment A => heating single phase (solid) ice up to melting pt.

Segment B => melting of ice => 2 phases in contact (s & l) ΔT = ∅.

Segment C => heating single phase (liquid) water up to boiling pt.

Segment D => boiling of liquid => 2 phases in contact (l & g). ΔT = ∅.

Segment E => heating single phase (steam) up to desired temperature.

For what it's worth, the equation for the segments that show increasing temperature values is q = mcΔT (m= mass, c = specific heat & ΔT temp change.

The segments with zero slopes (horizontal lines) are defined by equations  q = m·ΔHₓ where m = mass & ΔHₓ = heat of fusion (a constant = 335 j/g). The same is true for the line at 100°C where q = m·ΔH(v) where m = mass & ΔH(v) is the heat of vaporization (a constant = 2259 j/g.

Calculations involve calculating the amount heat transfer for each segment individually and then adding the heat values to obtain the total heat transfer.

Answer:

0.448 mols

Explanation:

Use balanced equation:

2H2 + O2 -> 2H2O

For every one mole of oxygen, there are two moles of water

hence the molar ratio 1:2

So if there are 0.224 mols of oxygen

Water = 0.224×2

Which is 0.448 mols of H20

Answer:

[tex]30^{\circ}\text{C}[/tex]

Explanation:

To know the temperature at which KCl dissolves in water we need to refer to the general solubility curves.

In the case of [tex]KCl[/tex], [tex]35\ \text{g}[/tex] of it will dissolve in [tex]100\ \text{g}[/tex] of water at a minimum temperature of [tex]30^{\circ}\text{C}[/tex].

So, the the minimum temperature needed to dissolve 35 grams of KCl in 100 grams of water is [tex]30^{\circ}\text{C}[/tex].

At STP, 1 mole of any gas occupies 22.4 L of space. Since we are given STP conditions here, we can use this ratio to determine the number of moles of CO gas: (32.8 L CO)/(22.4 mol CO/L CO) = 1.51 mol CO.

So, there are 1.51 moles of CO gas.

Answer:

605.6mg of quinine

Explanation:

Based on Lambert-Beer's law, the intensity of an optical measurement is directely proportional to its concentration.

Unknown concentration gives a reading of 327

100 ppm gives 180 of intensity

The concentration of the diluted quinine tablet is:

327 * (100ppm / 180) = 181.67 ppm. The final dilution

The concentration of the first diluted solution is:

181.67 ppm * (100.0mL / 15mL) = 1211ppm

ppm could be defined as mass of solute (In this case of quinine) in mg per liter of solution. That is:

1211mg / L

As the tablet was diluted to 500mL = 0.5L, the mass of the quinine is:

0.5L * (1211mg / L) =

Answer:

B) an error occurred, the mass of the reactants should equal the mass of the products.

Explanation:

The answer choices are:

A) no error occurred, some of the products are always lost as heat.

B) an error occurred, the mass of the reactants should equal the mass of the products.

C) an error occurred, the products should weigh more than the reactants.

D) no error occurred, water is not weighed when determining the weight of the products.

The basis to answer this question is the law of conservation of mass.

Any chemical reaction satisfies the law of conservation of mass: mass cannot be either created nor destroyed, so, always, the mass of the reactants equal the mass of the products.

Thus, since he measured the mass of his reactant materials to be 35g and he reported that his products weighed 32g, his data are in clear contradiction of the law of conservation of mass. So, there is an error in his results: the mass of the reactants should equal the mass of the products.

An error occurred, the mass of the reactants should equal the mass of the products according to law of conservation of mass for the given experiment. Therefore, the correct option is option B.

The mass of the reactants and products in a chemical reaction should be equal, in accordance with the law of conservation of mass. This implies that there is no net change in mass during the chemical process. The mass of the reactants and products in a chemical reaction should be equal, in accordance with the law of conservation of mass. This implies that there is no net change in mass during the chemical process.

Franklin determined the mass of the reactant components in this instance to be 35g, and the products of the reaction weighed 32g. An error occurred because the mass of the reactants should equal the mass of the products, but the mass of the products is less than the mass of the reactants.

Therefore, the correct option is option B.

Answer:

0.917 L

Explanation:

Step 1: Given data

Step 2: Calculate the moles corresponding to 36.0 g of Ca(OH)₂

The molar mass of Ca(OH)₂ is 74.09 g/mol.

36.0 g × 1 mol/74.09 g = 0.486 mol

Step 3: Calculate the volume of the solution

Molarity is equal to the moles of solute divided by the liters of solution.

M = moles of solute / liters of solution

liters of solution = moles of solute / M

liters of solution = 0.486 mol / (0.530 mol/L) = 0.917 L

Answer: Temperature is an objective measurement of how hot or cold an object is. It can be measured with a thermometer or a calorimeter. It is a means of determining the internal energy contained within a given system.

Explanation:

Answer:

Temperature is a physical quantity that expresses hot and cold

Explanation:

Temperature is a physical quantity that expresses hot and cold. This is how the air feels and how hot/cold something is. The less tight the atoms are, the hotter something is. The more tight the atoms are, the cooler something is.

1Al2(SO4)3 + 3ZnCl2 → 2AlCl3 + 3ZnSO4

The coefficients represents moles. There is 1 mole of Aluminum Sulfate, 3 moles of Zinc(II) Chloride, 2 moles of Aluminum Chloride, and 3 moles of Zinc(II) Sulfate.

Now add all the coefficients/moles.

9 is the sum of all the coefficients.
