Answer the following questions:
Answer variants:
because sunlight energy is absorbed by animals
\(2FeSO_4\)(s) \(\xrightarrow[]{Heat}\) \(Fe_2O_3\)(s) + \(SO_2\)(g) + \(SO_3\)(g)
because sunlight energy is absorbed by plants
\(AuNO_3\)(aq) + \(NaCl\)(aq) \(\xrightarrow[]{Heat}\) \(AgCl\)(s) + \(NaNO_2\)(aq)
\(AgNO_3\)(aq) + \(NaCl\)(aq) \(\xrightarrow[]{Heat}\) \(AgCl\)(s) + \(NaNO_3\)(aq)
\(CuO\) + \(2HCl\) → \(CeCl_2\) + \(2H_2O\)
1. Write a balanced chemical equation for the reaction between sodium chloride and silver nitrate indicating the physical state of the reactants and the products.
2. Why is photosynthesis considered an endothermic process?
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)
