Oxide 1 is a solid which reacts with dilute hydrochloric acid. Oxide 2 is a gas which reacts with sodium hydroxide solution. What are the formulae for these oxides?
- AOxide 1: $\text{CaO}$, Oxide 2: $\text{MgO}$
- BOxide 1: $\text{MgO}$, Oxide 2: $\text{NO}_2$
- COxide 1: $\text{NO}_2$, Oxide 2: $\text{SO}_2$
- DOxide 1: $\text{SO}_2$, Oxide 2: $\text{CaO}$
