a) \(n_{CO_2}=\dfrac{4,48}{22,4}=0,2\left(mol\right)\)
\(n_{NaOH}=0,3.1=0,3\left(mol\right)\)
Xét tỉ lệ \(\dfrac{n_{NaOH}}{n_{CO_2}}=\dfrac{0,3}{0,2}=1,5\)
=> Tạo ra muối NaHCO3, Na2CO3
b)
PTHH: 2NaOH + CO2 --> Na2CO3 + H2O
0,3----->0,15------>0,15
Na2CO3 + CO2 + H2O --> 2NaHCO3
0,05<---0,05---------------->0,1
=> \(\left\{{}\begin{matrix}m_{Na_2CO_3}=\left(0,15-0,05\right).106=10,6\left(g\right)\\n_{NaHCO_3}=0,1.84=8,4\left(g\right)\end{matrix}\right.\)
