Well a molecule of water is equal to 1 Oxygen and 2 Hydrogen each, so it'd be 2 molecules of water
The formula equation for the reaction between zinc sulfide and magnesium arsenate is
3ZnS + Mg₃(AsO₄)₂ → Zn₃(AsO₄)₂ + 3MgS
<h3>What is a chemical equation? </h3>
Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.
The reactants are located on the left side while the products are located on the right side.
Reactants —> Products
The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
<h3>How to write the formula equation </h3>
Zinc sulfide => ZnS
Magnesium arsenate => Mg₃(AsO₄)₂
Zinc arsenate => Zn₃(AsO₄)₂
Magnesium sulfide => MgS
Zinc sulfide + Magnesium arsenate → Zinc arsenate + Magnesium sulfide
3ZnS + Mg₃(AsO₄)₂ → Zn₃(AsO₄)₂ + 3MgS
