The food flavor enhancer monosodium glutamate (MSG) has the composition 13.6% Na, 35.5% C, 4.8% H, 8.3% N and 37.8% O by mass. What is the empirical formula of MSG?

Answers

Answer 1

Answer:

C₅H₈NO₄Na

Explanation:

Step 1: Given data

Percentage by mass of Na in MSG: 13.6%Percentage by mass of C in MSG: 35.5%Percentage by mass of H in MSG: 4.8%Percentage by mass of N in MSG: 8.3%Percentage by mass of O in MSG: 37.8%

Step 2: Divide each percentage by the atomic mass of the element

Na: 13.6/22.99 = 0.592

C: 35.5/12.01 = 2.96

H: 4.8/1.01 = 4.75

N: 8.3/14.00 = 0.592

O: 37.8/16.00 = 2.36

Step 3: Divide all the number by the smallest one, i.e. 0.592

Na: 0.592/0.592 = 1

C: 2.96/0.592 = 5

H: 4.75/0.592 ≈ 8

N: 0.592/0.592 = 1

O: 2.36/0.592 ≈ 4

The empirical formula of MSG is C₅H₈NO₄Na.

Answers

Answer:

[tex]8.314\ \text{m}^3\text{Pa/mol K}[/tex]

Explanation:

Let us find the unit of the gas constant R from the ideal gas equation. We substitute the units of the quantities rearrange them and get the units of the gas constant.

P = Pressure = Pa

V = Volume = [tex]\text{m}^3[/tex]

n = Moles = mol

T = Temperature = K

[tex]PV=nRT\\\Rightarrow R=\dfrac{PV}{nT}\\\Rightarrow R=\dfrac{\text{Pa m}^3}{\text{mol K}}[/tex]

Here, [tex]\text{Pa}[/tex] is used so the gas constant value that must be used is [tex]8.314\ \text{m}^3\text{Pa/mol K}[/tex].

How long does it take light to travel from the Earth to the Sun? The speed of light is 2.998×10^5 km/s and the Sun is 1.496×10^8 km away from Earth, on average.

Answers

To solve this we must be knowing each and every concept related to speed. Therefore, 5x10⁵s it take light to travel from the Earth to the Sun.

What is speed?

Speed may be defined as the distance traveled by an item in the amount of time it requires to travel that distance. In other words, it measures how rapidly an item travels but does not provide direction. The term "velocity" refers to the combination of direction and speed.

The average speed is the total distance traveled by the item in a particular time frame. A scalar quantity is average speed. The magnitude of a scalar quantity indicates that it has no direction.

Mathematically,  

speed of light=2.998 x 10⁵m/s.

Time = (1.496x10⁸ km x 1000m/km) / (2.998 x  10⁵ m/s)

       =5x10⁵s

Therefore, 5x10⁵s it take light to travel from the Earth to the Sun.

Determine the theoretical yield of P4 if 293.5 g Ca3(PO4)2 and 378.5 g SiO2 are heated. (No Response) g If the actual yield of P4 is 44.9 g, determine the percent yield of P4.

Answers

Answer:

76.6% is percent yield of P₄

Explanation:

Percent yield is defined as 100 times the ratio of actual yield and theoretical yield. To solve this quesiton we need to find the theoretical yield of the reaction. Using:

2Ca₃(PO₄)₂(s) + 6SiO₂(s) → 6CaSiO₃(l) + P₄O₁₀(g)

P₄O₁₀(g) + 10C(s) → P₄(g) + 10CO(g)

We need to find the moles of Ca₃(PO₄)₂ and SiO₂ to find limiting reactant. With limiting reactant we can find moles of P₄O₁₀ = Moles of P₄. We must convert the moles of P₄ to mass using Molar mass (P₄ = 123.895g/mol):

Moles Ca₃(PO₄)₂ -Molar mass: 310.1767g/mol-

293.5g * (1mol / 310.1767g) = 0.9462moles

Moles SiO₂ -Molar mass: 60.08g/mol-:

378.5g * (1mol / 60.08g) = 6.30 moles

For a complete reaction of 6.30 moles of SiO₂ there are required:

6.30 moles SiO₂ * (2 moles Ca₃(PO₄)₂ / 6 moles SiO₂) =

2.10 moles Ca₃(PO₄)₂. As there are just 0.9462 moles, Ca₃(PO₄)₂ is limiting reactant

Moles P₄O₁₀ = Moles P₄:

0.9462moles Ca₃(PO₄)₂ * (1mol P₄O₁₀ / 2 mol Ca₃(PO₄)₂) = 0.4731 moles P₄O₁₀ = Moles P₄.

The mass is:

0.4731 moles P₄ * (123.895g / 1mol) = 58.6g = Theoretical yield.

Percent yield is:

44.9g / 58.6g * 100 =

76.6% is percent yield of P₄

Which atom is oxidized in the reaction of benzhydrol with bleach?

Answers

Answer:

Which atom is oxidized in the reaction of benzhydrol with bleach?

Explanation:

n this experiment, students will perform a simple oxidation reaction of a secondary

alcohol. Recall that Oxidation Is a Loss of electrons while Reduction Is a Gain of electrons (OIL

RIG). In order to apply this mnemonic, you must know the oxidation states of each atom within

the compound, with particular interest on carbon. Carbon can carry oxidation states ranging

from -4 to +4. A few examples are shown in Figure 1 below. It is also common for carbon to

carry an oxidation state of -3, -1, +1, and +3.

Figure 1. Examples of carbon’s oxidation levels.

You may have noticed that all of the compounds in Figure 1 are neutral and carbon has

zero formal charge in each example. The concept of oxidation state and formal charge are

similar with one important difference in the calculation. Both are calculated by taking the

difference between the valence electrons (from the periodic table) and the number of electrons

belonging to that atom within the molecule. For a given atom, the valence electrons will never

change but the electrons ‘belonging’ the atom in the molecule will vary depending on number of

lone pairs and attachments to more or less electronegative atoms. The important difference in

the calculation of oxidation states and formal charge is based on the following assignment of

bonding electrons (Figure 2). This is how the highlighted carbon in ethanol can have an

oxidation state of -1 but a formal charge of zero.

- Oxidation states assign bonding electrons to the more electronegative atom in a bond,

except when the two atoms are the same and the bonding electrons are split equally.

Answer:

so the reaction would probably would be a chemical reaction

"When benzophenone reduces to diphenylmethanol, leftover products include the CH2OH and NaBH3 species. The energetic CH2OH and NaBH3 quickly bond to give (CH2OH)H3B-Na+. This complex is the main second product of benzophenone reduction."

Reactant Ratios

"In life, four benzophenone molecules react with each BH4 complex. Since four benzophenone molecules each attract a hydrogen atom from the “BH4” hydrogen donor, four “CH2OH”s bond with each boron (B) atom. Realistically, the secondary product is (CH2OH)4B-Na+ and four diphenylmethanol molecules. Focusing on one benzophenone molecule at a time is helpful for explaining and understanding reaction steps."

What type of particle has no mass or charge?
A) Alpha
B) Beta
C) Gamma
D) Proton

Answers

Answer:

Your answer would be C.

Explanation:

Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.

Gamma particles has no mass or charge.

What are gamma radiations?

Gamma radiations is a kind of radiations, which are emitted during a nuclear reaction. Gamma radiations are emitted in the form of photons of energy, they did not carry any particles like alpha, beta and proton. So, because of not carrying any particle this radiations have no mass and as it is on the form of energy they also do not carry any charge.

Hence, the particles which has no mass or charge is gamma.

The density of Diamond is 3.51 g/cm3, and the density of platinum is 21.43 g/cm3. If equal masses of diamond and platinum are transferred to equal volumes of water in separated graduated cylinders, which graduated cylinder would have the greatest volume change

Answers

Answer:

Explanation:

Diamond has lesser density than platinum . So , if we take equal mass of both , the volume of mass of platinum will be far less .

The density of both diamond and platinum are  more than water so both of them will be drowned in water completely . They will not float . On being drowned , platinum will displace lesser volume of water because of its less volume . So volume change in case of platinum mass will be far less . The volume change for diamond will be more because of its bigger size.

You have been provided 100 ml of a 1000 ug/ml barium standard. What volume of this standard must be diluted to a final volume of 50 ml using DI water to produce a 30 ug/mL standard

Answers

Answer:

1. 0.1712M

2. 6.86mg/mL Ca, 12.14mg/mL Cl, 6860000ug/L Ca, 12140000ug/L Cl, 6860mg/L Ca, 12140mg/L Cl, 6860ug/mL Ca, 12140ug/mL Cl.

3. 6860ppm Ca and 12140ppm of Cl.

4. 1.5mL of the 1000ug/mL barium standatd must be taken.

Explanation:

1. Molarity is defined as the amount of moles of solute (Calcium chloride) present in 1L of solution.

The moles of CaCl₂ are:

1.9g CaCl₂ * (1mol / 110.98g) = 0.01712 moles

In 100mL = 0.10L:

0.01712mol / 0.10L = 0.1712M

2. The masses of Calcium and Chloride ions are:

1.9g * (40.078g Ca / 110.98g) = 0.686g Ca

And:

1.9g - 0.686g Ca = 1.214g Cl

mg/mL:

686mg Ca / 100mL = 6.86mg/mL Ca

1214mg Cl / 100mL = 12.14mg/mL Cl

ug/L:

686000ug / 0.1L = 6860000ug/L Ca

1214000ug/ 0.1L = 12140000ug/L Cl

mg/L:

686mg Ca / 0.1L = 6860mg/L Ca

1214mg Cl / 0.1L = 12140mg/L Cl

ug/mL:

686000ug Ca / 100mL = 6860ug/mL Ca

1214000ug Cl / 100mL = 12140ug/mL Cl

3. ppm are defined as mg/L, the ppm of Ca are 6860ppm Ca and 12140ppm of Cl

4. The solution must be diluted from 1000ug/mL to 30ug/mL, that is a dilution of:

1000ug/mL / 30ug/mL:

33.33 times must be diluted the solution.

As final volume of the diluted solution must be 50mL, the volume of the standard needed is:

50mL / 33.33 times = 1.5mL of the 1000ug/mL barium standatd must be taken

If 0.200 moles of NO are produced, how many moles of copper (I) nitrate produced?

Since the ratio between the two reactants according to the chemical equation is 1:3, we would need .03 moles of one to fully react with .01 moles of the other. Since we don't, only 1/150 mole of the first reactant will react with the .02 moles of the second reactant. This will produce .02 moles of KNO3 as well as .01 moles of Al(OH)3

.02 moles KNO3 = .02(48 grams + 14 grams + 40 grams) = .02(102 grams) = 2.04 grams

A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of pentane, ethanolamine, diethylamine, glycerol, and carbon tetrachloride. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density pentane 0.63gmL, ethanolamine 1.0gmL, diethylamine 0.71gmL, glycerol 1.3gmL, carbon tetrachloride 1.6gmL Next, the chemist measures the volume of the unknown liquid as 1737.cm3 and the mass of the unknown liquid as 1.23kg . Calculate the density of the liquid. Be sure your answer has the correct number of significant digits.

Answers

Answer:

0.71 g/mL

The liquid is diethylamine

Explanation:

Mass of the liquid = 1.23 kg of 1.23 * 10^3 g

Volume of the liquid = 1737.cm3

Let us remember that density is obtained as;

Density= mass/volume

Density= 1.23 * 10^3 g/1737cm^3

Density= 0.71 g/cm^3

Since we know that 1 mL=1 cm3 . So, 1 g/mL=1 g/cm3

So we can also write;

Density= 0.71 g/mL

The liquid is diethylamine

Answers

Answer:

.0466 L

Explanation:

To start off, use dimensional analysis to convert everything to standard PV=nRT units.

[tex]\frac{39.0}{1}[/tex] x [tex]\frac{1}{1000}[/tex] = .039 L

[tex]\frac{802}{1}[/tex] x [tex]\frac{1}{760}[/tex] = 1.055 atm

17 +273 = 290

...and so on.

Solve for n for the starting pressure, volume and temp. You'll need it for the final equation.

n= PV/RT [tex]\frac{1.055 *.039}{.0821 * 290}[/tex]= .0017 number of moles

Solve for volume of the end point.

V= nRT/P [tex]\frac{.0017*.0821*280}{.838}[/tex] = .0466 L of helium, or 46.6ml Less pressure means it will take up more space.
