Balance the following equations. Mg + H 2 SO 4 → MgSO 4 + H 2

The balancing of the chemical equation is very important. For balancing a chemical equation, the total number of atoms of the reactants and products should be equal. The balanced equation is given below: Mg + H 2 SO 4 → MgSO 4 + H 2

Balance the following equations. CaCO 3 + HCl → CaCl 2 + H 2 O + CO 2

The balancing of the chemical equation is very important. For balancing a chemical equation, the total number of atoms of the reactants and products should be equal. The balanced equation is given below: CaCO 3 + 2 HCl → CaCl 2 + H 2 O + CO 2

Balance the following equations. CaO + H 2 O → Ca ( OH ) 2

The balancing of the chemical equation is very important. For balancing a chemical equation, the total number of atoms of the reactants and products should be equal. The balanced equation is given below: CaO + H 2 O → Ca ( OH ) 2

Balance the following equations. Ag + HNO 3 → AgNO 3 + H 2 O + NO 2

The balancing of the chemical equation is very important. For balancing a chemical equation, the total number of atoms of the reactants and products should be equal. The balanced equation is given below: Ag + 2 HNO 3 → AgNO 3 + H 2 O + NO 2
