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

Look at picture
ASAP please will mark as brainlist don’t got much time
Answer:
question 4. 69.19J
question 5. 40835.84J
Explanation:
question4.
heat needed = mass × specific heat capacity × change in temperature
= 9.3× 0.240×(52-21)
=69.192J
question 5.
heat added = 160× 4.184×(85-24)
= 40835.84J

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.
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.

Convert 8.00 x 1020 molecules of H2 to moles.
Answer:
1.33 x 10^-3 mol H2
Explanation:
? mol H2 = 8.00 x 1020^20 molecules H2 x 1 mol H2/6.02 ! 1023 molecules H2 = 1.33 x 10^-3 mol H2
Hope that helps!
8.00 x 10²⁰ molecules of H₂ present in 1.33 x 10⁻³ mole of H₂.
What is mole?Mole is used to define the amount of quantity of any substance and 1 mole equals to the 6.023 × 10²³ elementary entities or atoms in it.
According to the question:
1 mole of H₂ = 6.023 × 10²³ molecules of H₂
or 1 molecules of H₂ = 1 mole of H₂ / 6.023 × 10²³ molecules of H₂
To convert 8.00 x 10²⁰ molecules into mole we calculate as follow:
x mole of H₂ = (8.00 x 10²⁰ molecules x 1 mole of H₂) / 6.023 × 10²³ molecules
x mole = 1.33 x 10⁻³ mole
Hence, 1.33 x 10⁻³ mole of H₂ consist 8.00 x 10²⁰ molecules.
