1) Answer :- 12 moles O2.
The given reaction is
Form reaction it is clear that,
4 moles of water produced from 6 moles of oxygen.
ie. 4 mol of water = 6 mol of oxygen
therefore,
8 mol of water = of oxygen.
therefore, 12 mol of oxygen will require to produce 8 mol of water.
--------------------
2) Answer :- 108 g NaCl
The given balanced reaction is
from reaction
theoretical Ratio of moles of reactants, Na:Cl2 =
Given :-
Mass of Na = 58.8 g
Molar mass of Na = 23 g/mol
Mass of Cl2 = 65.5 g
Molar mass of Cl2 = 71 g/mol
we know
therefore,
Moles of Na =
Moles of Cl2 =
therefore
Ratio of actual moles of Na:Cl2 is
ie. theoretical mol ratio < actual mol ratio.
Hence, Cl2 is limiting reagent.
Thus theoretical yield is calculated from Cl2
from reaction
1 mol of Cl2 = 2 mol of NaCl
therefore,
0.923 mol of Cl2 = of NaCl.
Now,
Molar mass of NaCl = 58.5 g/mol.
therefore,
Mass of NaCl =
