Question

one mole of mixture of CO and CO2 requires 20gm.NaOH to convert all the CO2 into Na2CO3.hiw many more grams of NaOH would it require for conversion into Na2CO3,if the mixture is completely oxidised into CO2

Answer 1

2 NAOH + CO₂ — > Na₂CO₃ + H₂O

Mole ratio :

1 : 2

We need 2 moles of NaOH to convert one mole of CO₂ to Na₂CO₃.

Moles of NaOH :

20 / 40 = 0.5 moles

Moles of CO₂ :

0.5/ 2 = 0.25

Moles of CO are:

1 - 0.25 = 0.75 moles.

Oxidation of CO :

CO + 1/2 O₂ —> CO₂

Mole ratio is 1 : 1

Moles of CO₂ formed are 0.75 moles.

Thus is half the moles of NaOH required.

NaOH required is thus :

2 × 0.75 =1.5 moles

1 mole — > 40 g

1.5 moles —>?

1.5 × 40 = 60g

60 g is required

Answer 2

Answer:

above bro how is the mole ratio 1:2
