\(n_{hh}=\dfrac{14,874}{24,79}=0,6\left(mol\right)\)
Khí thoát ra là khí CH4
\(n_{CH_4}=\dfrac{6,1975}{24,79}=0,25\left(mol\right)\)
\(CH\equiv CH+Br_2\rightarrow CH_2Br-CH_2Br\)
0,35-------> 0,35
a)
\(\%V_{CH_4}=\%n_{CH_4}=\dfrac{0,25.100\%}{0,6}=41,67\%\)
\(\%V_{C_2H_2}=\%n_{C_2H_2}=\dfrac{0,35.100\%}{0,6}=58,33\%\)
b)
\(CM_{Br_2}=\dfrac{0,35}{0,25}=1,4\left(M\right)\)
c)
\(CH_4+2O_2\underrightarrow{t^o}CO_2+2H_2O\)
0,25--> 0,5
\(C_2H_2+\dfrac{5}{2}O_2\underrightarrow{t^o}2CO_2+H_2O\)
0,35--> 0,875
\(V_{O_2}=24,79.\left(0,5+0,875\right)=34,08625\left(l\right)\)
