Question

2 moles of CA(HCO3)2 on heating forms 1 mole of CO2. THE % YIELD OF CO2 IS?​

Answer 1

Answer:

i think it will be 100%....

Explanation:

here we have mole of CO2 so we can calculate mass by which we can calculate % yield......by using formula ..actual yield ÷ calculated yield× 100...

hope I help u....

Answer 2

Answer:

25%

Explanation:

Ca(HCO3)2 --------> CaO + 2CO2 + H2O

1 mole                                  2 moles

therefore, 1 mole of calcium hydrogen carbonate=2 moles of co2

so, 2 moles of calcium hydrogen carbonate=4 moles of co2 (theoretical yield)

% yield=actual yield/theoretical yield * 100

here, actual yield= 1 mole of co2 (given)

theoretical yield= 4 mole of co2

% yield=1/4 * 100

= 25%
