a) SO2+Ca(OH)2---->CaSO3 +H2O
b) Ta có
n\(_{SO2}=\frac{3,36}{22,4}=0,15\left(mol\right)\)
Theo pthh
n\(_{Ca\left(OH\right)2}=n_{SO2}=0,15\left(mol\right)\)
C\(_{M\left(Ca\left(OH\right)2\right)}=\frac{0,15}{0,25}=0,6\left(M\right)\)
c) Theo pthh
n\(_{CaSO3}=n_{SO2}=0,15\left(mol\right)\)
m\(_{CaSO3}=0,15.120=18\left(g\right)\)
Chúc bạn học tốt
