a. PTHH: S + O2 ---to---. SO2 (1)
Ta có: \(n_S=\dfrac{9,6}{32}=0,3\left(mol\right)\)
Theo PT(1): \(n_{SO_2}=n_S=0,3\left(mol\right)\)
=> \(V_{SO_2}=0,3.22,4=6,72\left(lít\right)\)
b. PTHH: SO2 + Ca(OH)2 ---> CaSO3↓ + H2O (2)
Theo PT(2): \(n_{CaSO_3}=n_{SO_2}=0,3\left(mol\right)\)
=> \(m_{CaSO_3}=0,3.120=36\left(g\right)\)
\(n_S=\dfrac{9,6}{32}=0,3\left(mol\right)\)
PTHH: S + O2 ---to→ SO2
Mol: 0,3 0,3
\(V_{SO_2}=0,3.22,4=6,72\left(l\right)\)
PTHH: SO2 + Ca(OH)2 → CaSO3 + H2O
Mol: 0,3 0,3
\(m_{CaSO_3}=0,3.120=36\left(g\right)\)
