Explanation / Answer

1.             2 Na       +         2 H2O --> 2 NaOH +   H2

0.297 moles     0.133 moles            

a) 2 moles of sodium are reacting with 2 moles of water. That is, Reactants should be in 1:1

      As water is present in less amount so water is a limiting reagent.

b) 2 moles of water is giving 2 moles of sodium hydroxide so 0.133 moles of water will give 0.133 moles of Sodium Hydroxide.

2.   .             CO       +         H2O --> CO2    +     H2

                     0.431 moles 0.534 moles

a) 1 mole of carbon mono oxide is reacting with 1 mole of water. That is, Reactants should be in 1:1

As carbon mono oxide is present in less amount so carbon mono oxide is a limiting reagent.

b) 1 moles of carbon mono oxide is giving 1 moles of carbon dioxide so 0.431 moles of carbon mono oxide will give 0.431 moles of carbon dioxide.
