Ta có :
\(n_{CO2}=\frac{3,36}{22,4}=0,15\left(mol\right)\)
\(n_{Ca\left(OH\right)2}=\frac{37}{74}=0,5\left(mol\right)\)
\(PTHH:Ca\left(OH\right)2+CO2\rightarrow CaCO3+H2O\)
=>nCa(OH)2 dư=0,5-0,15=0,35(mol)
\(\Rightarrow\text{mCaCO3=0,15x100=15(g)}\)
CO2+Ca(OH)2--->CaCO3+H2O
a) n\(_{CO2}=0,15\left(mol\right)\)
n\(_{Ca\left(OH\right)2}=\frac{37}{74}=0,5\left(mol\right)\)
---->Ca(OH)2 dư-->tạo 1 muối
b) Theo pthh
n\(_{CaCO3}\)=nCO2=0,15(mol)
m CaCO3=0,15.100=15(g)
