15.45 grams of solid potassium chlorate decomposes when heated to form solid potassium chloride and oxygen gas. Assuming 100% yield, how many grams of solid potassium chloride will be produced? Solid magnesium combines with fluorine gas producing solid magnesium fluoride. How much magnesium metal is required to produce exactly 50.0 grams of the magnesium fluoride product?

Exactly 100.0 grams of solid calcium oxide is combined with exactly 100.0 grams of solid diphosphorus pentoxide. This reaction produces solid calcium phosphate. Assuming 100% yield, how many grams of solid calcium phosphate will be produced?

i know this a lot please try to show work any help is appreciated
