Chemistry help PLEASE!!
A solution of hydrazine (N2H4) was standardized by titration with sodium bromated (NaBrO3). It required 25.62 mL of hydrazine solution to react completely with 3.8101 grams of sodium bromated. The unbalanced reaction is: N2H4(l) + BrO3^- (aq) —> Br^- (aq) + N2(g)
a) balance the equation
b) calculate the molarity of the hydrazine solution
c) how many grams of N2 are produced?

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
