Answer:
Q = 0.144
Explanation:
- C(s) + H2O(g) ↔ CO(g) + H2(g)
reaction quotient:
- Q = [H2(g)][CO(g)] / [H2O(g)][C(s)]
∴ [C(s)] = 10.0 mol/2.50 L = 4 M
∴ [H2O(g)] = 16.0 mol/2.50 L = 6.4 M
∴ [CO(g)] = 3.30 mol/2.50 L = 1.32 M
∴ [H2(g)] = 7.00 mol/2.50 L = 2.8 M
⇒ Q = (2.8 M)(1.32 M) / (6.4 M)(4 M)
⇒ Q = 0.144
Answer:

Explanation:
Answer:
2KClO3 —> 2KCl + 3O2
The coefficients are 2, 2, 3
Explanation:
From the question given above, we obtained the following equation:
KClO3 —> 2KCl + 3O2
The above equation can be balance as follow:
There are 2 atoms of K on the right side and 1 atom on the left side. It can be balance by putting 2 in front of KClO3 as shown below:
2KClO3 —> 2KCl + 3O2
Now, the equation is balanced.
Thus, the coefficients are 2, 2, 3
