Consider the balanced chemical equation,

mgcl2(aq) + 2agf(aq) → 2agcl(s) + mgf2(aq)

if both reactants are completely consumed and we produce 20 formula units of agcl, how many ions of mg and f did we start with?

a) 10 ions of mg and 20 ions of f

b) 10 ions of mg and 10 ions of f

c) 20 ions of mg and 10 ions of f

d) 20 ions of mg and 20 ions of f

How is electrolysis most commonly used to produce an energy source? a - splitting water molecules produces oxygen, which organisms breathe to fuel their bodies. b - splitting water molecules produces hydrogen gas, which is used to power machines through hydrogen fuel cells. c - splitting carbon dioxide molecules produces coal, a form of carbon that can be burned to produce heat. d - splitting carbon dioxide molecules produces natural gas, which can be burned to generate electricity in power plants.
