Which will not appear in the equilibrium constant expression for the reaction below?
H2O(g) + C(s) <->H2(g) + CO(g)
1.[H₂O]
2.[C]
3.[Hz]
4.[CO]
Please help!

[C]

Explanation:

H20 does not appear when it is a liquid because pure water has a concentration of 1. However, you must notice that it is a gas in this problem so it must be entered.

The Reason C is not is because it is a solid. solids also have a concentration of 1 and are not necessary to calculate Ka or Kb

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
