Answer:
The equilibrium will shift to produce less ammonia
Explanation:
According to Le Chatelier's principle, the reaction will try to oppose anything that is done on it, if it was at equilibrium.
When the concentration of H2 is decreased, you are decreasing the concentration of hydrogen so the reaction tries to increase the concentration of hydrogen by breaking down the ammonia on the products side. This will decrease the output of ammonia
Answer:
This is an acid-base reaction (neutralization): H 2SO 4 is an acid, Ca(OH) 2 is a base.
...
1 H2SO4 + Ca(OH)2 → H2O + CaSO4
2 H2SO4 + Ca(OH)2 → CaSO4 + HOH
3 H2SO4 + Ca(OH)2 → H2O + CaOH2SO4
4 H2SO4 + Ca(OH)2 → H2O + Ca(HSO4)2
5 H2SO4 + Ca(OH)2 → H2O + (CaOH)2SO4
