\(T=\dfrac{n_{NaOH}}{n_{CO_2}}\)
a.
\(T=\dfrac{1}{2}=0.5< 1\)
\(\Rightarrow\) Tạo muối NaHCO3
\(NaOH+CO_2\rightarrow NaHCO_3\)
\(1..................................1\)
\(m_{NaHCO_3}=1\cdot84=84\left(g\right)\)
b.
\(T=\dfrac{2}{1}=2\)
=> Tạo muối Na2CO3
\(2NaOH+CO_2\rightarrow Na_2CO_3+H_2O\)
\(2.................................1\)
\(m_{Na_2CO_3}=1\cdot106=106\left(g\right)\)
c.
\(T=\dfrac{3}{2}=1.5\)
=> Tạo 2 muối
\(n_{Na_2CO_3}=a\left(mol\right),n_{NaHCO_3}=b\left(mol\right)\)
\(n_{NaOH}=2a+b=3\left(mol\right)\)
\(n_{CO_2}=a+b=2\left(mol\right)\)
\(\Rightarrow a=b=1\)
\(m_{Muối}=1\cdot84+1\cdot106=190\left(g\right)\)
