Answer:
The system will shift to the right (Forward).
Explanation:
Based on the equilibrium:
2CO(g) + O2(g) ⇄ 2CO2(g)
If the amount of O2 is increased: The equilibrium will shift to the right trying to decrease this concentration following the Le-Ch principle that says:
A change in an equilibrium will be counteracted by the system producing a response that restore the initial state.

Answer:
The number before any molecular formula applies to the entire formula. So here you have five molecules of water with two hydrogen atoms and one oxygen atom per molecule. Thus you have ten hydrogen atoms and five oxygen atoms in total.
HA+ BCO3 -> BA + H2O + CO2
or
acid + some carbonate -> salt + water + carbon dioxide
the acid is neutralized and produces a salt, water, and co2
