Question

match the definition in column a with the term in column b.
column a

1. a homogeneous mixture
2. states that mass is neither created nor destroyed in a chemical reaction
3. states that regardless of the amount, a compound is always composed of the same elements in the same proportion by mass
4. states that different masses of one element combine with the same relative mass of another element to form different compounds
5. the grid organizing elements into periods and groups
6. the ratio of the mass of each element to the total mass of the compound
7. three physical forms that describe all matter that exists on earth
8. a separation technique that results in the formation of pure solid particles from a solution
9. a technique that separates the components of a mixture
10. a form of matter with a constant volume that takes the shape of its container
11. a form of matter with a definite shape and volume

column b
a. law of multiple proportions
b. percent by mass
c. periodic table
d. law of conservation of mass
e. law of definite proportion
f. solution
g. crystallization
h. chromatography
i. states of matter
j. solid
k. liquid

Explanation:

1. A homogeneous mixture is a solution.
2. The law stating mass is conserved in a chemical reaction is the law of conservation of mass.
3. The law stating a compound has a fixed mass - proportion of elements is the law of definite proportions.
4. The law about different masses of one element combining with a fixed mass of another is the law of multiple proportions.
5. The grid organizing elements is the periodic table.
6. The ratio of element mass to compound mass is percent by mass.
7. The three physical forms of matter are states of matter.
8. The separation technique forming pure solid particles from a solution is crystallization.
9. A technique to separate mixture components is chromatography.
10. A form of matter with constant volume taking container shape is a liquid.
11. A form of matter with definite shape and volume is a solid.

Answer:

1. f. solution
2. d. law of conservation of mass
3. e. law of definite proportions
4. a. law of multiple proportions
5. c. periodic table
6. b. percent by mass
7. i. states of matter
8. g. crystallization
9. h. chromatography
10. k. liquid
11. j. solid
