Here are the essential concepts you must grasp in order to answer the question correctly.
Chemical Equations
Chemical equations represent the reactants and products in a chemical reaction. They must be balanced to obey the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Each element's number of atoms must be the same on both sides of the equation, ensuring that the total mass remains constant.

Formation Reactions
A formation reaction is a specific type of chemical reaction where elements combine to form a compound. In these reactions, the elements are in their standard states, and the reaction produces one mole of the compound. Understanding how to write formation reactions is essential for constructing balanced equations for compounds like sodium sulfate.

Sodium Sulfate Composition
Sodium sulfate (Na2SO4) is composed of sodium (Na), sulfur (S), and oxygen (O). To write the balanced equation for its formation, one must recognize that it is formed from its constituent elements: sodium metal, sulfur, and oxygen gas. The correct stoichiometry must be applied to ensure that the number of each type of atom is conserved in the balanced equation.
