1 mole of CO2 has 6.02 x 10^23 molecules of CO2. Say x moles of CO2 has 3.0x10^23 molecules of CO2. Therefore x = 3/6.02 = 0.50. M = 0.50 * (12 + 2x16) = 0.50 * 44 = 22g
A halogen is example of
nonmetal. The answer is letter A. When compounds containing halogens they are
called salts thus the name “salt – former”. Halogen consists of Fluorine,

Explanation:
Alkali Metals (Group 1) elements experience an increase in the vigour of their reaction in water as they go down the group (as the atomic number increase). As such the most reactive Alkali Metal would be

Quite frankly, you do not want Francium to react with water- that's a huge explosion on your hand.
