Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants. ... Individual CFC molecules are labeled with a unique numbering system

Answer:
According to google, "About five million million hydrogen atoms could fit. Some factors would affect that number like the area of the head and the size of atoms (as well as attractions between atoms). Some atoms are larger than others." Is this accurate? I'm not sure. Good luck! :)
Answer:
Increases
Explanation:
The main reason of increase earth's temperature is the increase of CO2 gas in the air which causes global warming and the ice burgs in the poles are getting melted and it results in the increase of the sea water level.
This is the main our problem in the future.
Answer:
Mass = 16.7 g
Explanation:
Given data:
Volume = 125 mL (125/1000 =0.125 L)
Molarity = 2.50 M
Mass in grams of solute = ?
Solution:
First of all we will calculate the number of moles:
<em>Molarity = number of moles solute / volume in litter</em>
2.50 M = Number of moles of solute/ 0.125 L
Number of moles of solute = 2.50 M × 0.125 L
Number of moles of solute = 0.313 mol
Grams of solute:
<em>Number of moles = mass / molar mass</em>
Mass = number of moles × molar mass
Mass = 0.313 mol × 53.5 g/mol
Mass = 16.7 g
