a) S + O2 --to--> SO2
b) \(n_S=\dfrac{3,2}{32}=0,1\left(mol\right)\)
PTHH: S + O2 --to--> SO2
0,1-->0,1------->0,1
=> \(V_{O_2}=0,1.22,4=2,24\left(l\right)\)
=> \(V_{kk}=2,24:20\%=11,2\left(l\right)\)
d) \(m_{SO_2}=0,1.64=6,4\left(g\right)\)
\(n_S=\dfrac{3,2}{32}=0,1\left(mol\right)\\ a,PTHH:S+O_2\rightarrow\left(t^o\right)SO_2\\ b,n_{O_2}=n_{SO_2}=n_S=0,1\left(mol\right)\\ b,V_{O_2\left(đktc\right)}=0,1.22,4=2,24\left(l\right)\\ c,V_{kk}=\dfrac{100}{20}.V_{O_2\left(đktc\right)}=5.2,24=11,2\left(l\right)\\ d,m_{SO_2}=64.0,1=6,4\left(g\right)\)
Chắc câu b là V oxi em nhỉ? Anh tính như thế rồi nha ^^
