CaC2 + 2H2O ==> C2H2 + Ca(OH)2
moles of C2H2 produced = moles of Ca(OH)2 produced (1:1 mole ratio is the stoichiometry)
moles of Ca(OH)2 produced = 7 g x 1mol/74.1 g = 0.0945 moles
moles C2H2 = 0.0945 moles
grams C2H2 = 0.0945 moles x 26 g/mole = 2.46 grams = 2 grams to 1 sig fig
Following the Law of Conservation of Mass (see link below), there will be 20 grams of products in a reaction of 20 grams of reactions.

The mass of nitrous oxide is 262,8 g.
Nothing is produced, 500g potassium chlorate will be the same 500 g potassium chlorate after reaction. Actually there is no reaction at all.
Depends on what the last reaction is. And probably what the first reaction was too. Insufficient information in the question.
