Answer the following questions:
Answer variants:
\(CuO\) + \(2HCl\) → \(CeCl_2\) + \(2H_2O\)
\(2Pb(NO_3)_2\) \(\xrightarrow[]{Heat}\) \(2PbO\) + \(4NO_2\) + \(O_2\)
combination reaction
because sunlight energy is absorbed by animals
single displacement reaction
\(2FeSO_4\)(s) \(\xrightarrow[]{Heat}\) \(Fe_2O_3\)(s) + \(SO_2\)(g) + \(SO_3\)(g)
1. Balance the following chemical equation: \(Pb(NO_3)_2\) → \(PbO\) + \(NO_2\) + \(O_2\)
2. Identify the type of reaction in the following example: \(2H_2\)(g) + \(O_2\)(g) → \(2H_2O\)(l).
3. Balance the given chemical equation:
\(FeSO_4\)(s) \(\xrightarrow[]{Heat}\) \(Fe_2O_3\)(s) + \(SO_2\)(g) + \(SO_3\)(g)
\(FeSO_4\)(s) \(\xrightarrow[]{Heat}\) \(Fe_2O_3\)(s) + \(SO_2\)(g) + \(SO_3\)(g)
