Question
Consider the following statements
1. If all the reactants are not taken in their stoichiometric ratio, then at least one reactant will be left behind.
2. 2 moles of H2(g) and 3 moles of O2(g) produce 2 moles of water.
3. equal wt. of carbon and oxygen are taken to produce CO2 then O2 is limiting reagent.
The above statements 1, 2, 3 respectively are (T = True, F = False)

Options
A.T T T
B.F T F
C.F F F
D.T F T
Solution
(1) It is a fact.
(2) 2H2 + O2 → 2H2O
Initial mole 2 3 0
final mole 0 3-1 = 2 2
(3) C + O 2→ CO2

Here C is limiting reagent.
(2) 2H2 + O2 → 2H2O
Initial mole 2 3 0
final mole 0 3-1 = 2 2
(3) C + O 2→ CO2
Here C is limiting reagent.
