a. PTHH: \(S+O_2\underrightarrow{t^o}SO_2\\ 0,4mol:0,4mol\rightarrow0,4mol\)
b. \(n_S=\dfrac{12,8}{32}=0,4\left(mol\right)\)
\(V_{O_2}=0,4.22,4=8,96\left(l\right)\)
c. \(V_{kk}=\dfrac{8,96}{21\%}.100\%=42,,67\left(l\right)\)
a) \(S+O_2\underrightarrow{t^0}SO_2\)
b) \(n_S=\dfrac{12,8}{32}=0,4\left(mol\right)\)
\(PTHH:S+O_2\underrightarrow{t^0}SO_2\)
Theo PTHH: \(n_S:n_{O_2}=1:1\Rightarrow n_{O_2}=n_S=0,4\left(mol\right)\)
\(\Rightarrow V_{O_2\left(đktc\right)}=0,4.22,4=8,96\left(l\right)\)
c) \(V_{kk}=\dfrac{8,96}{21\%}.100\%=42,7\left(l\right)\)
