The solution would be like this for this specific problem:
First, we need to write
out the balanced reaction equation for the problem:<span>
"gaseous nitrogen with gaseous hydrogen to produce
gaseous ammonia"
gaseous nitrogen + gaseous hydrogen = gaseous ammonia
gaseous nitrogen = N2(g)
gaseous hydrogen = H2(g)
gaseous ammonia = NH3(g)
In here, I’m going to show you how to balance this from start
to finish:
N2(g) + H2(g) ↔ NH3(g) (basic, unbalanced equation that shows
reactants and product)
N2(g) + H2(g) ↔ 2NH3(g) (balances the nitrogens)
N2(g) + 3H2(g) ↔ 2NH3(g) (balances the hydrogens) =>
Balanced Equation
<span>Next, we write the Keq expression of the balanced reaction:
Keq = (∏[products]^n) /(∏[reactants]^n)
Keq = [NH3]^2 / [[N2][H2]]^3
Therefore, the correct
equilibrium constant expression is Keq = (NH3)2 / (N2)(H2)3.</span></span>
Answer:
Explanation:
Distance is the product of speed and time.
The speed is 8 kilometers per hour and the time is 4 hours.
Substitute the values into the formula and multiply. Note that the hours will cancel when multiplied.
Mr. Evans traveled <u>32 kilometers.</u>

Explanation:
To give 33.6 dm³ hydrogen gas at STP, 18.06 x 10²³ atoms of Na must react completely.
<h3>What is Mole concept ?</h3>
A mole is a unit of measurement used to measure the amount of any fundamental entity (atoms, molecules, ions) present in the substance.
As according to the given equation, 2 moles (ie 12.04 x 10²³ atoms) of Na-atoms produces 1 mole (22.4 ltr) of H₂-gas.
Hence, to produce 33.6 ltr (equivalent to 33.6 dm³) of H₂-gas produced by ;
= 12.04 x 10²³ atoms of Na / 22.4 ltr of H₂-gas x 33.6 ltr
= 18.06 x 10²³ atoms of Na
Hence, To give 33.6 dm³ hydrogen gas at STP, 18.06 x 10²³ atoms of Na must react completely.
