a)
\(C+O_2\rightarrow CO_2\)
\(S+O_2\rightarrow SO_2\)
b)
\(n_C=\frac{1,2}{12}=0,1\left(mol\right)\)
\(n_{O2}=\frac{6,72}{22,4}=0,3\left(mol\right)\)
\(n_S=0,3-0,1=0,2\left(mol\right)\)
\(m_S=0,2.32=6,4\left(g\right)\)
c)
\(\%n_{CO2}=\frac{0,1}{0,3}.100\%=33,33\%\)
\(\%n_{SO2}=100\%-33,33\%=66,67\%\)
a) C+O2-->CO2(1)
S+O2---->SO2(2)
b) n O2=6,72/22,4=0,3(mol)
n C=1,2/12=0,1(mol)
-->n O2(1)=0,1(mol)
n O2(2)=0,3-0,1=0,2(mol)
n S=n O2(2)=0,2(mol)
x=mS=0,2.32=6,4(g)
c) % n C=\(\frac{0,1}{0,1+0,2}.100\%=33,33\%\)
%n S=100%-33,33%=66,67%
