Match the following term to the correct definition
Column A
1. chemical change
2. physical change
3. chemical reaction
4. Law of Conservation of Mass
5. chemical equation
Column B
a. a process that produces a chemical change, in which substances are changed into new substances
b. a representation of a chemical reaction using chemical symbols and numbers
c. States that mass is neither created nor destroyed by chemical reactions or physical transformations
d. a change in which the chemical makeup of the substance is not changed
e. a change that takes place when atoms of one or more substances are rearranged into new combinations, forming one or more new substances
1 - e
2 - d
3 - a
4 - c
5 - b
1. chemical change - e. a change that takes place when atoms of one or more substances are rearranged into new combinations, forming one or more new substances
2. physical change - d. a change in which the chemical makeup of the substance is not changed
3. chemical reaction - a. a process that produces a chemical change, in which substances are changed into new substances
4. Law of Conservation of Mass - c. States that mass is neither created nor destroyed by chemical reactions or physical transformations
5. chemical equation - b. a representation of a chemical reaction using chemical symbols and numbers
To match the terms in Column A with their correct definitions in Column B, we can go through each definition and find the term that best fits.
1. Chemical change: Definition e. A change that takes place when atoms of one or more substances are rearranged into new combinations, forming one or more new substances.
2. Physical change: Definition d. A change in which the chemical makeup of the substance is not changed.
3. Chemical reaction: Definition a. A process that produces a chemical change, in which substances are changed into new substances.
4. Law of Conservation of Mass: Definition c. States that mass is neither created nor destroyed by chemical reactions or physical transformations.
5. Chemical equation: Definition b. A representation of a chemical reaction using chemical symbols and numbers.
So, the matching would be:
1. Chemical change - e
2. Physical change - d
3. Chemical reaction - a
4. Law of Conservation of Mass - c
5. Chemical equation - b
