True it does reduce the amount go greenhouses gases in the world
2.1.695 isn’t a real number?? but if it’s like number two on a paper it would be 1.695 x 104 - 1.395 x 1015=-1239.645
Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.
tell me if i'm wrong
Answer:

Explanation:
Reactants
Magnesium = 24.3 g
Hydrogen chloride= x g
Products
Hydrogen gas = 2.04 g
Magnesium chloride = 96.9 g
As the mass of the reactions is conserved we have
Mass of reactants = Mass of products

Mass of hydrogen chloride is
.
