An initial mixture of nitrogen gas and hydrogen gas is reacted in a rigid container at a certain temperature as follows:

Answers

Answer:

The concentration of nitrogen gas and hydrogen gas that reacted initially are 10.0 M and 11.0 M respectively.

Note: The question is incomplete. The complete question is as follows:

An initial mixture of nitrogen gas and hydrogen gas is reacted in a rigid container at a certain temperature as follows:

3H2(g)+N2(g)⇌2NH3(g)

At equilibrium, the concentrations are

[H2] = 5.0 M, [N2] = 8.0 M, and [NH3] = 4.0 M.

What were the concentrations of nitrogen gas and hydrogen gas that were reacted initially?

Explanation:

Given the following data:

Concentration of H2 at equilibrium = 5.0 M

Concentration of N2 at equilibrium = 8.0 M

Concentration of NH3 at equilibrium = 4.0 M

The given equilibrium reaction is,

Initial                    a             b            c

Change                -3x          -x         +2x

Equilibrium         (a-3x)       (b-x)     +2x

The value of x is calculated from the equilibrium of NH3

Concentration of NH3 at equilibrium = 4.0 M  = 2x

x = 2.0 M

Substituting the value of x above

Initial Concentration of H2:

a - 3 × 2.0 M = 5.0 M

a = 6.0 M + 5 = 11.0 M

Initial Concentration of N2:

b - 2.0 M = 8 M

b = 8.0 M + 2.0 M

b = 10.0 M

Therefore, the concentration of nitrogen gas and hydrogen gas that reacted initially are 10.0 M and 11.0 M respectively.

Why does lowering the pressure cause a liquid to boil?
A. It becomes easier for molecules to escape.
B. It pushes molecules out of the liquid.
C. It causes the temperature to rise.
D. It changes the volume of the liquid.

Answers

Lowering the pressure in a container will cause the liquid in the container to boil faster because it becomes easier for the molecules to escape.

What causes boiling?

Boiling happens when the vapor pressure of a liquid equals the atmospheric pressure.

By lowering the atmospheric pressure, the vapor pressure of a liquid takes a lower time to equal the atmospheric pressure.

Thus, it becomes easier for the molecules of the liquid to escape from each other.

it would be nitrogen
Out of the four Nitrogen is the most electronegative. Electronegative is basically determined by whichever atom is closest to F (the most electronegative)

Nitrogen is only a few electrons difference than Fluorine. Bromine is still quite electronegative but it has whole extra valence shells making it not as electronegative as nitrogen
