Increasing every day. in 2013, we had about 7.125 Billion. in 9160, we had closer to 3 billion. It is still on a pretty steady clime today.
The geosphere is about 99.94% of Earth's mass, so C is the answer.
Answer:
They are most likely solid
Explanation:
solid is a physical property
The percentage composition of CF4 is %C = 13.64% and %F = 86.36%
The solution are as follows:
Molar mass of CF4 = 88
<span>molar mass of C = 12 </span>
<span>molar mass of F = 4x19 = 76 </span>
<span>% C = 12/88 x 100 = 13.64% </span>
<span>% F = 76/88 x 100 = 86.36%</span>
- Corrosive<span> chemicals eat away and destroy things. </span>Flammable<span> things can be burned with fire. </span>
