Which of the following is the best synonym for the word stoichiometry?

• A. Thermodynamics
• B. Acid-base equilibrium
• C. Quantitative chemical calculation
• D. Chemical bonding

Answer: (C)

Verified step by step guidance

1. Understand that stoichiometry is a branch of chemistry that deals with the quantitative relationships between the amounts of reactants and products in a chemical reaction.
2. Recall that thermodynamics focuses on energy changes and heat transfer, which is different from stoichiometry's focus on quantities of substances.
3. Recognize that acid-base equilibrium involves the balance of acids and bases in solution, which is a specific topic and not synonymous with stoichiometry.
4. Note that chemical bonding describes how atoms connect to form molecules, which is a structural concept rather than a quantitative calculation.
5. Conclude that the best synonym for stoichiometry is 'Quantitative chemical calculation' because it directly relates to measuring and calculating the amounts of substances involved in chemical reactions.
