Question

match each term with the best description.

• chemical equation
• hydrate
• mole
• precipitation reaction
• products
• reactants
• stoichiometry

descriptions:

• the chemical compounds that are present before a reaction occurs
• the compounds produced from the reaction
• unit of measure, containing avogadros number
• the quantitative proportion of reactants to products
• two solutions are mixed and an insoluble substance forms
• an illustration of the reaction that occurs between two or more chemical compounds
• a solid compound that contains water molecules

Explanation:

To solve the matching, we analyze each term:

• Chemical equation: Represents the reaction between compounds, so matches "An illustration of the reaction...".
• Hydrate: A solid with water molecules, matches "A solid compound that contains water molecules".
• Mole: Unit with Avogadro’s number, matches "Unit of measure, containing Avogadro’s number".
• Precipitation reaction: Involves mixing solutions to form an insoluble substance, matches "Two solutions are mixed and an insoluble substance forms".
• Products: Compounds produced from the reaction, matches "The compounds produced from the reaction".
• Reactants: Compounds before the reaction, matches "The chemical compounds that are present before a reaction occurs".
• Stoichiometry: Deals with reactant - product proportions, matches "The quantitative proportion of reactants to products".

Answer:

• Chemical equation: An illustration of the reaction that occurs between two or more chemical compounds
• Hydrate: A solid compound that contains water molecules
• Mole: Unit of measure, containing Avogadro’s number
• Precipitation reaction: Two solutions are mixed and an insoluble substance forms
• Products: The compounds produced from the reaction
• Reactants: The chemical compounds that are present before a reaction occurs
• Stoichiometry: The quantitative proportion of reactants to products
