Unit 6 Review - Chemical equations

What is the law that states mass is neither created nor destroyed in a chemical reaction?

• Law of Definite Proportions

• Law of Conservation of Mass

• Law of Multiple Proportions

• Law of Constant Composition

• Decomposition

• Single Replacement

• Synthesis

• Combustion

Predict the products of the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH).

• Synthesis

• Decomposition

• Single Replacement

• Double Replacement

Which of the following is a single replacement reaction?

Explain why the mass of reactants equals the mass of products in a chemical reaction.

• Because energy is absorbed

• Due to the Law of Conservation of Mass

• Because atoms are destroyed

• Due to the Law of Definite Proportions
