\(n_{C2H2}=0,05\left(mol\right)\)
\(C_2H_2+\frac{5}{2}O_2\underrightarrow{^{to}}2CO_2+H_2O\)
0,05____0,125__0,1____________
\(V_{O2}=0,125.22,4=2,8\left(l\right)\)
\(\Rightarrow V_{kk}=2,8.20\%=14\left(l\right)\)
\(CO_2+2NaOH\rightarrow Na_2CO_3+H_2O\)
0,1____0,2_______________________
\(\Rightarrow V_{NaOH}=\frac{0,2}{0,2}=1\left(l\right)1000\left(ml\right)\)
