(a)
Interpretation: To write the balanced
Concept Introduction: The representation of the chemical formulas of a substance that react and the substance that are produced is called as chemical equation. In this the number of atoms of the reactants and the atoms of products should be balanced that is the number of atoms should be same on both the sides of a chemical equation.

(b)
Answer to Problem 120A
Explanation of Solution
Aluminum Sulfide on reacting with water will result in the formation of Aluminum hydroxide and hydrogen sulfide. On the reactant side 1 moles of aluminum sulfide and 6 moles of water is made to react that result in the formation of 2 moles of Aluminum hydroxide and 3 moles of Hydrogen sulfide. These moles on either side of the reaction will make it a balanced reaction.
