In column A, we have various terms related to chemical changes and reactions, while in column B, we have their corresponding explanations. Let's match the terms with their explanations.
1. Chemical change: a change that takes place when atoms of one or more substances are rearranged into new combinations, forming one or more new substances. Therefore, term 1 matches explanation c.
2. Physical change: a change in which the chemical makeup of the substance is not changed. Hence, term 2 corresponds to explanation b.
3. Chemical reaction: a process that produces a chemical change, in which substances are changed into new substances. This means term 3 matches explanation a.
4. Law of Conservation of Mass: states that mass is neither created nor destroyed by chemical reactions or physical transformations. So, term 4 matches explanation e.
5. Chemical equation: a representation of a chemical reaction using chemical symbols and numbers. Therefore, term 5 corresponds to explanation d.
To summarize:
1. chemical change: c. 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: b. 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: e. states that mass is neither created nor destroyed by chemical reactions or physical transformations.
5. chemical equation: d. a representation of a chemical reaction using chemical symbols and numbers.
