a) PTHH: \(CH_4+2O_2\xrightarrow[]{t^o}CO_2+2H_2O\)

b) Ta có: \(n_{CH_4}=\dfrac{2,24}{22,4}=0,1\left(mol\right)\) \(\Rightarrow n_{O_2}=0,2\left(mol\right)\)

\(\Rightarrow V_{O_2}=0,2\cdot22,4=4,48\left(l\right)\)

c) Ta có: \(\left\{{}\begin{matrix}n_{CO_2}=0,1\left(mol\right)\\n_{NaOH}=\dfrac{40\cdot25\%}{40}=0,25\left(mol\right)\end{matrix}\right.\) \(\Rightarrow\) Tạo muối trung hòa

PTHH: \(2NaOH+CO_2\rightarrow Na_2CO_3+H_2O\)

Vì NaOH còn dư nên tính theo CO2 

\(\Rightarrow n_{Na_2CO_3}=n_{CO_2}=0,1\left(mol\right)\) \(\Rightarrow m_{Na_2CO_3}=0,1\cdot106=10,6\left(g\right)\)
