a) \(S+O_2\underrightarrow{t^0}SO_2\)
b) \(m_S+m_{O_2}=m_{SO_2}\)
c) \(n_S=\dfrac{3,2}{32}=0,1\left(mol\right)\)
Theo PTHH: \(n_{O_2}:n_S=1:1\)
\(\Rightarrow n_{O_2}=n_S=0,1\left(mol\right)\)
\(\Rightarrow m_{O_2}=0,1.32=3,2\left(g\right)\)
d) \(V_{O_2\left(đktc\right)}=0,1.22,4=2,24\left(l\right)\)
e) Theo PTHH: \(n_{SO_2}:n_S=1:1\)
\(\Rightarrow n_{SO_2}=n_S=0,1\left(mol\right)\)
\(\Rightarrow m_{SO_2}=0,1.64=6,4\left(g\right)\)
a) S+O2---->SO2
c)nS=3,2/32=0,1(mol)-->nO2=0,1(mol)--->mO2=32*0,1=3,2 (g)
