Book Free Demo1. Balance the following chemical equations and identify the type of chemical reaction.
(e) \(CaO\)(s) + \(SiO_2\)(s) → \(CaSiO_3\)(s)
In the above equation, calcium oxide (\(CaO\)) reacts with silicon dioxide (\(SiO_2\)) to produce calcium silicate (\(CaSiO_3\)), a new product. This is a reaction.
The balanced chemical equation for the statement is
\(CaO\)(s) + \(SiO_2\)(s) → .
2. Balance the following chemical equations and identify the type of chemical reaction.
(f) \(H_2O_2\)(l) \(\xrightarrow[]{UV}\) \(H_2O\)(l) + \(O_2\)(g)
In the above equation, In the presence of UV (ultraviolet) radiation, hydrogen peroxide (\(H_2O_2\)) into water (\(H_2O\)) and oxygen (\(O_2\)). Therefore this is a (photochemical) reaction.
The balanced chemical equation for the statement is
\(2H_2O_2\)(l) \(\xrightarrow[]{UV}\) \(2H_2O\)(l) + \(O_2\)(g).
