How many moles of NaHCO3 ? Mass of NaHCO3 = 2.0g

There are 2.1x10^-2 moles of C2H3O2H

Which one is limiting and which is excess

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.
