PTHH: \(CaO+CO_2\rightarrow CaCO_3\)
Ta có: \(n_{CaCO_3}=\dfrac{10}{100}=n_{CaO}=n_{CO_2}\)
\(\Rightarrow\left\{{}\begin{matrix}m_{CaO}=0,1\cdot56=5,6\left(g\right)\\V_{CO_2}=0,1\cdot22,4=2,24\left(l\right)\end{matrix}\right.\)
\(n_{CaCO_3}=\dfrac{10}{100}=0.1\left(mol\right)\)
\(CaCO_3\underrightarrow{^{^{t^0}}}CaO+CO_2\)
\(0.1............0.1.......0.1\)
\(m_{CaO}=0.1\cdot56=5.6\left(g\right)\)
\(V_{CO_2}=0.1\cdot22.4=2.24\left(l\right)\)
