Question

1. drag and drop the terms with the descriptions.

any substance that undergoes a chemical change in a chemical reaction
a substance formed from another substance as a result of a chemical reaction
a compound that speeds up a chemical reaction without undergoing a chemical
change
a balanced chemical reaction expressed in symbols
the state in which a process and its reverse are occurring at equal rates so that
no overall change is taking place

Explanation:

1. For "any substance that undergoes a chemical change in a chemical reaction", the term is "reactant" as reactants are the starting substances that change in a reaction.
2. For "a substance formed from another substance as a result of a chemical reaction", the term is "product" as products are formed from reactants in a reaction.
3. For "a compound that speeds up a chemical reaction without undergoing a chemical change", the term is "catalyst" as catalysts increase reaction rate without being consumed.
4. For "a balanced chemical reaction expressed in symbols", the term is "chemical equation" (assuming "chemi" is a typo for "chemical equation") as chemical equations represent reactions with symbols.
5. For "the state in which a process and its reverse are occurring at equal rates so that no overall change is taking place", the term is "equilibrium" (assuming "equili" is a typo for "equilibrium") as equilibrium is the state of equal forward and reverse reaction rates.

Answer:

1. any substance that undergoes a chemical change in a chemical reaction: reactant
2. a substance formed from another substance as a result of a chemical reaction: product
3. a compound that speeds up a chemical reaction without undergoing a chemical change: catalyst
4. a balanced chemical reaction expressed in symbols: chemical equation
5. the state in which a process and its reverse are occurring at equal rates so that no overall change is taking place: equilibrium
