Here are the essential concepts you must grasp in order to answer the question correctly.
Chemical Reactions
A chemical reaction involves the transformation of reactants into products through the breaking and forming of chemical bonds. In this case, zinc (Zn) reacts with hydrochloric acid (HCl) to produce zinc chloride and hydrogen gas. Understanding the types of reactions, such as single displacement, is crucial for balancing equations.

Balancing Chemical Equations
Balancing a chemical equation ensures that the number of atoms for each element is the same on both sides of the equation, adhering to the law of conservation of mass. This process involves adjusting coefficients in front of compounds to achieve balance, which is essential for accurately representing the reaction.

Stoichiometry
Stoichiometry is the quantitative relationship between reactants and products in a chemical reaction. It allows chemists to calculate the amounts of substances consumed and produced, which is vital for balancing equations and predicting the outcomes of reactions. In the given reaction, stoichiometry helps determine the correct coefficients for Zn and HCl.
