Consider the reaction 2NaN3 → 2Na + 3N2, which is the first reaction that occurs when an air bag expands in a car undergoing a collision. This reaction happens very quickly, as you might suspect.

A graph showing the amount of nitrogen gas (N2) could be best described as which sentence?

A.) The graph line’s general trend is decreasing from left to right.
B.) The graph line’s general trend is absolutely horizontal.
C.) The graph line’s general trend is nearly horizontal.
D.) The graph line’s general trend is increasing from left to right.

Answers

Answer 1

Answer:

D) The Graph line’s general trend is increasing from left to right.

Explanation:

N2, a product, will increase over time which means the line of the graph would go up over time. Time increases from left to right so the correct answer is D.

Answer 2

The graph that describes the reaction will have a trend in which the graph is decreasing from left to right.

What is a collision?

A collision occurs when two particle bump into each other. We know that a reaction takes place when there is an effective collision between the reacting particles.

In this case, the graph that describes the reaction will have a trend in which the graph is decreasing from left to right.

Answers

Explanation:

A carbon radical is a reaction intermediate, which is produced during a free-radical reaction. These carbon radicals contain one unpaired electron on a carbon atom. Hence, these radicals are highly reactive in nature.

A free-radical reaction results in the production of a carbon radical as a reaction intermediate.

What is radical in chemistry?

A radical in chemistry is indeed an atom, molecule, and ion that possesses one least one unpaired electron electron. The term "radical" is sometimes used to refer to a free radical. These unpaired electrons provide radicals, with a few exceptions, a high degree of chemical reactivity. Radicals frequently dimerize on their own. The majority of organic radicals have brief lives.

A free-radical reaction results in the production of a carbon radical as a reaction intermediate. One unpaired electron is present on the carbon atom in these radical forms of carbon. As a result, the nature of these radicals is very reactive.

Therefore, a free-radical reaction results in the production of a carbon radical as a reaction intermediate.

An unknown gas with a mass of 205 g occupies a volume of 20.0 L at 273 K and 1.00 atm. What is the molar mass of this compound?

Answers

The molar mass of this compound is 0.004 m/g

Firstly, molar mass is moles/grams so we need to solve for the number of moles and we were already given the grams (205 g).

So to solve for moles we were given 205 g, 20.0 L, 273 K and 1.00 atm. Knowing these numbers we can plug them into the ideal gas law, PV=nRT

where P is pressure, V is volume, n is number of moles, R is the gas constant (in this case it is 0.08206) and T is the temperature.

[tex]PV=nRT\\\\n=\frac{PV}{RT}\\\\n=\frac{1.00*20.0}{0.08206*273} =0.893[/tex]

Next, we use moles and grams to solve for molar mass:

[tex]\frac{0.893}{205} =0.004[/tex]

In the electroplating of nickel, 0. 200 faraday of electrical charge is passed through a solution of niso4. What mass of nickel is deposited?.

Answers

The mass of nickel, Ni deposited when 0.2 faraday of electrical charge is passed through a solution of NiSO₄ is 5.9 g

Balanced equation

Ni²⁺ + 2e —> Ni

Molar mass of Ni = 59 g/mol

Mass of Ni from the balanced equation = 1 × 59 = 59 g

Number of faraday = 2

SUMMARY

From the balanced equation above,

2 faraday deposited 59 g of Nickel

How to determine the mass of nickel deposited

From the balanced equation above,

2 faraday deposited 59 g of Nickel

Therefore,

0.2 faraday will deposit = (0.2 × 59) / 2 = 5.9 g of Nickel

Thus, 5.9 g of Nickel were deposited in the process

Consider the reaction 3CH4(g)→C3H8(g)+2H2(g).
Calculate ΔG at 298 K if the reaction mixture consists of 41 atm of CH4 , 0.013 atm of C3H8 , and 2.3×10−2 atm of H2 .
Given:
ΔH for...
CH4 = -74.8 C3H8 = -103.85 H2 = 0
ΔS for...
CH4 = 0.1863 C3H8 = 0.2699 H2 = 0.13058
ΔG for...
CH4 = -50.8 C3H8 = -23.4 H2 = 0
ΔG at 298 K = 128.9 kJ

Answers

From the calculations performed, the free energy change for the reaction is 72 kJ/mol.

What is the equilibrium constant?

The equilibrium constant is a value that shows the extent to which reactants have been converted to products.

Given that the equation of the reaction is;

3CH4(g)→C3H8(g)+2H2(g)

Then;

PC3H8 = 0.013 atm

PH2 =  2.3×10−2 atm

PCH4 = 41 atm

Now;

ΔG = ΔG° + RTlnQ

ΔG°reaction = ΔG°products - ΔG°reactants

ΔG°reaction = [( -23.4) +2(0)] - 3(-50.8)

ΔG°reaction = 129 kJ/mol

Q = PC3H8 * PH2^2/PCH4^3

Q = 0.013 * (2.3×10−2)^2/( 41)^3

Q = 6.877 * 10^-6/68921

Q= 9.9* 10^-11

Hence;

ΔG = 129 * 10^3  + [8.314 * 298 * (ln  9.9* 10^-11 )]

ΔG = 129 * 10^3 - 57073

ΔG = 72 kJ/mol
