The gas produced when a mixture of sodium propanoate and soda lime is heated is
methane
pentane
ethane
butene
ethyne
Spiegazione
So during the presence of methane, sodium ethanoate with soda lime is used, using sodium propanoate with sodium will produce ethane according to the equation below
\(\CH_3CH_2COONa + NaOH → C_2H_6 + Na_2CO_3\)\ + CO\(_2\)
There are two gases but from the options provided, ethane is the correct answer.
