Question 1

What is a mixture?

Answer 1

A mixture is any combination of substances in which the substances are not combined on the chemical level.

Question 2

What can different substances be described that can be called a mixture?

Answer 2

The different substances in a mixture can be large enough to be seen with the naked eye, like pebbles in sand, or they can be so small that the mixture looks like it has a uniform composition.

Question 3

What 2 things are considered a pure substance?

Answer 3

Element or compound

Gold, water, and air

Question 4

How are mixtures different from chemical compounds?

Answer 4

The parts in a mixture do not chemically combine, and they may be found in a variety of ratios.

Question 5

What is a solution? Give an example

Answer 5

One substance called the solute is dissolved in a substance called the solvent.

Question 6

What are the 2 main times of mixtures?

Answer 6

homogeneous and heterogeneous mixtures

Question 7

Describe the differences between the 2 main types of mixtures.

Answer 7

Homogeneous mixtures are evenly mixed, heterogeneous mixtures are not evenly mixed and can be physically separated.

Question 8

What is a colloid? Give an example

Answer 8

Heterogenous mixture in which the particles are well mixed not dissolved and able to be seen under a microscope.

Question 9

What is a suspension? Give an example

Answer 9

Heterogeneous mixture where particles settle out. Salad dressing

Question 10

What is an emulsion? Give an example

Answer 10

Emulsions are a type of colloid that allows things to mix together that do not normally mix.

Question 11

What are the ways you can separate heterogeneous mixtures?

Answer 11

Decanting, filtration, sifting. Just picking out.

Question 12

How can suspensions be separated?

Answer 12

Suspensions can be separated by allowing the particles to sink to the bottom of the liquid.

Question 13

How can colloids be separated?

Answer 13

They need to be heated or chilled

Question 14

How you separate mixtures is dependent on the what?

Answer 14

Its Composition

Question 15

How can you separate salt from a mixture?

Answer 15

By evaporating the water

Question 16

Heterogeneous solid and liquid

Answer 16

Solid- salad liquid - salad dressing

Question 17

Colloid examples

Answer 17

mayo, hairspray, shaving cream, and whipped cream

Question 18

How can you separate sugar from a mixture?

Answer 18

Use alcohol to separate out the sugar. Salt does not dissolve in alcohol, so the sugar will dissolve and the salt will be left behind.
