Balance the following equation: Pb NO 3 2 + Heat → PbO s + NO 2 g + O 2 ( g )

Balanced chemical equation is; 2 Pb NO 3 2 ( S ) + Heat → 2 PbO s + 4 NO 2 g + O 2 ( g ) When lead nitrate is heated, it forms lead oxide, nitrogen dioxide and oxygen.

Balance the following equation: Fe s + H 2 O g → Fe 3 O 4 s + H 2 ( g )

A balanced chemical equation follows the law of conservation of mass. According to this law number of atoms of each element in a chemical reaction should be equal on both left-hand side and right-hand side of a chemical equation. The balanced equation for given reaction is: 3 Fe s + 4 H 2 O g → Fe 3 O 4 s + 4 H 2 g

Balance the following equation: FeSO 4 s heat → Fe 2 O 3 s + SO 2 g + SO 3 ( g )

A balanced chemical equation follows the law of conservation of mass. According to this law number of atoms of each element in a chemical reaction should be equal on both left-hand side and right-hand side of a chemical equation. The balanced equation for given reaction is: 2 FeSO 4 s + Heat → Fe 2 O 3 ( s ) + SO 2 ( g ) + SO 3 ( g )
