Answer the following questions:
1. Complete the missing components/variables given as 'x' and 'y' in the following reaction:
\(Pb(NO_3)_2\)(aq) + \(2KI\)(aq) → \(PbI_2\)(x) + \(2KNO_3\)(y)
\(Pb(NO_3)_2\)(aq) + \(2KI\)(aq) →
This is an example of and a double displacement reaction.
2. The decomposition of ferrous sulphate is exothermic or endothermic in nature?
\(2FeSO_4\)(s) \(\xrightarrow[]{Heat}\) .
The decomposition of ferrous sulphate is an reaction because it includes heat absorption to generate ferric oxide (\(Fe_2O_3\)), sulphur dioxide (\(SO_2\)), and sulphur trioxide (\(SO_3\)).
