10.0 g CaCO3 excess HCl 3.65 g CO2 percent yield

 

 

Calcium carbonate reacts with hydrochloric acid solution

to form calcium chloride solution, water, and carbon dioxide gas.

What is the percentage yield of carbon dioxide

if 3.65 g of the gas is collected

when 10.0 g of calcium carbonate

is reacted with excess hydrochloric acid?

산-염기 반응

CaCO3 + 2HCl → CaCl2 + H2O + CO2

( 참고 https://ywpop.tistory.com/20866 )

 

 

 

10.0 g CaCO3 반응 시,

CO2의 이론적 수득량 = 4.4 g

( 참고 https://ywpop.tistory.com/14150 )

 

 

 

수득 백분율 = (실제 수득량 / 이론적 수득량) × 100

= (3.65 / 4.4) × 100

= 82.95%

( 참고 https://ywpop.tistory.com/61 )

 

 

 

답: 83.0%
