b. How many grams of NaAlO2 is  using the same amount of NaOH?

c. Which reactant is the limiting reagent?

d. How many grams of the excess reagent is left?

2. An aqueous solution of NaOH candissolve an aluminum sheet in the reaction:
2 Al +2 NaOH + 2H20 +2 NGALO2 + 3 H2
If 126.4 g of NaOH is 97.7 g of Al are made to react,
a. How many moles of NAAIO, is produced if 126.4 g of NaOH reads completely?
b. How many grams of NAAIO, is produced using the same amount of NaOH?
c. Which reactant is the limiting reagent?
d. How many grams of the excess reagent is left?
