For each of the following unbalanced equations, calculate many grams of each product would be produced by com reaction of 12.5 g of the reactant indicated in **. cate clearly the mole ratio used for the conversion a. TiBr4(g) + *H2*(g) --> Ti(s) + HBr(g)
b. *SiH4*(g) + NH3(g) --> Si3N4(s) + H2(g)
c. NO(g) + *H2*(g) → N2(g) + 2H2O(l)
d. *Cu2S*(s) → Cu(s) + S(g)
