Question 19

QUESTIONS

Question 20

Determine the number of atoms of each element in the following compounds

H2O
CO2

Answer 20

2 hydrogen 1 oxygen
1 carbon 2 oxygen

Question 21

Describe the differences between adhesion and cohesion. Give an example of each.

Answer 21

Adhesion is an attraction between molecules of different chemical substances. Cohesion is an attraction between molecules or atoms of the same substance.

Ex: water sticking to the glass is an example of adhesion, but the water that sticks to the surface of the glass pulls more water up behind it because of cohesion.

Question 22

What is polarity? Why is water polar?

Answer 22

Polarity is an uneven distribution of electrons.
H2O is polar because charges are unevenly distributed.

Question 23

Why is carbon special?

Answer 23

They can bond together to form very long, durable chains
