What two things do produce when atoms bond ?

1. Carbon Dioxide

2. Water Vapor

Explanation:

When atoms bond with oxygen in the air it goes through a process called oxidation. When carbon bonds with oxygen, it produces carbon dioxide; a colorless gas. When hydrogen bonds with oxygen, it produces water vapor.

I believe the answer is 0.83

Explanation:

The formula for density is p=m/v

p-density

m-mass

v-volume

To find volume you multiply 4*6*4

Which will give you 96

We know the mass which is 80.0        

So, p=80/96= 0.83

I really hope this helps.
