Answer 13

C?

Answer 14

an element is only one type of atom

Answer 15

or sorry A?

Answer 16

yes, A is correct :)

They have different properties.
They can be divided into elements.

Answer 18

B?

Answer 19

correct ^_^

Answer 20

By the combination of an unlimited number of elements
By creating and destroying protons of different atoms
By the combinations of many atoms of the same element
By losing, gaining, or sharing electrons between other atoms

Answer 22

so A?

Answer 23

I don't think it is possible to combine an unlimited number of elements... we'd get a black hole haha

Answer 24

oh okay, so d?

Answer 25

right! :D

Answer 26

Which type of mixture can be separated using distillation?

A compound with elements of different boiling points
Homogeneous mixture with components of different boiling points
A compound with elements of similar boiling points
Homogeneous mixture with components of similar boiling points

Answer 27

b? ^

Answer 30

I'm not sure on the true definition and process of distillation, but I'm thinking:

compounds, as we said in the previous question, is bound together by sharing electrons. so compounds CANNOT be separated by simply boiling

Answer 31

distilling's purpose is to separate substances from each other by boiling.
if they have the same boiling temperatures, then all the your stuff might boil away.
if they have different temperatures, then you can boiling one of the substances away at a lower temperature, then you can be left with the substance that didn't get boiled away

Answer 32

okay last one :)
