CaCO3 \(\underrightarrow{to}\) CaO + CO2
Theo định luật bảo toàn khối lượng:
\(m_{CaCO_3}=m_{CaO}+m_{CO_2}\)
\(\Leftrightarrow m_{CaO}+m_{CO_2}=10\left(g\right)\)
Ta có: \(\left\{{}\begin{matrix}\dfrac{m_{CaO}}{m_{CO_2}}=\dfrac{14}{11}\\m_{CaO}+m_{CO_2}=10\end{matrix}\right.\Rightarrow\left\{{}\begin{matrix}m_{CaO}=5,6\left(g\right)\\m_{CO_2}=4,4\left(g\right)\end{matrix}\right.\)
