Question

match each term with the correct answer choice. then write the number of each term in the magic square. when you add the numbers in the columns, rows, and diagonals the sums should all be the same.

1. precipitate
2. example of color change
3. chemical change
4. exothermic reaction
5. chemical reaction
6. example of production of gas
7. flammability
8. chemical property
9. endothermic reaction

a. baking soda and vinegar bubbling and fizzing when combined together
b. a solid substance formed from a liquid solution
c. a characteristic that can only be observed by changing the identity of a substance
d. a measure of how quickly a specific material is capable of catching fire and burning
e. a chemical change that occurs when two or more substances combine to form a new substance.
f. a change that results in the formation of new chemical substances
g. mixing two clear liquids and the solution turns pink
h. energy is absorbed causing the temperature of a substance to decrease
i. energy is released causing the temperature of a substance to increase

Explanation:

1. A precipitate is a solid from a liquid solution (B).
2. Mixing two clear - liquids and getting a pink solution is a color change (G).
3. A chemical change forms new chemical substances (F).
4. An exothermic reaction releases energy and increases temperature (I).
5. A chemical reaction is a change that forms new substances (E).
6. Baking soda and vinegar bubbling is gas production (A).
7. Flammability is how quickly a material can catch fire (D).
8. A chemical property is observed by changing a substance's identity (C).
9. An endothermic reaction absorbs energy and decreases temperature (H).

Answer:

1. B. A solid substance formed from a liquid solution
