Question

1,How many grams of potassium chlorate must be decomposed to
produce 288g of oxygen?(k=39 ,Cl=35 5 O=16)
KClO3-----> KCl + 3O2
2,How many grams of oxygen can be prepared by the decomposition of
12g of mercury(ll) oxide? (atomic masses; Hg=200 O=16)
2HgO-------> 2Hg + O2
3,what mass of aluminium would be completely oxidized by 44 8L of
