PTHH: \(S+O_2\rightarrow SO_2\\ 0,4:0,4\rightarrow0,4\)
\(n_s=\dfrac{12,8}{32}=0,4\left(mol\right)\)
a. \(V_{SO_2}=0,4.22,4=8,96\left(l\right)\)
b. \(V_{O_2}=0,4.22,4=8,96\left(l\right)\)
S + O2 \(\underrightarrow{to}\) SO2
\(n_S=\dfrac{12,8}{32}=0,4\left(mol\right)\)
a) Theo PT: \(n_{SO_2}=n_S=0,4\left(mol\right)\)
\(\Rightarrow V_{SO_2}=0,4\times22,4=8,96\left(l\right)\)
b) Theo PT: \(n_{O_2}=n_S=0,4\left(mol\right)\)
\(\Rightarrow V_{O_2}=0,4\times22,4=8,96\left(l\right)\)
\(\Rightarrow V_{KK}=5V_{O_2}=5\times8,96=44,8\left(l\right)\)
\(n_S=\dfrac{12,8}{32}=0,4\left(mol\right)\)
PTHH: \(S+O_2\underrightarrow{t^o}SO_2\)
a. Theo PT ta có: \(n_S=n_{O_2}=n_{SO_2}=0,4\left(mol\right)\)
Thể tích khí SO2 sinh ra (ở đktc) là:
\(V_{SO_2}=0,4.22,4=8,96\left(l\right)\)
b.
\(V_{O_2}=0,4.22,4=8,96\left(l\right)\)
