CaCO3 \(\underrightarrow{to}\) CaO + CO2
a) \(n_{CaCO_3}=\dfrac{150}{100}=1,5\left(mol\right)\)
Theo PT: \(n_{CaO}lt=n_{CaCO_3}=1,5\left(mol\right)\)
\(\Rightarrow m_{CaO}lt=1,5\times56=84\left(g\right)\)
\(\Rightarrow H=\dfrac{80}{84}\times100\%=95,24\%\)
b) \(n_{CaO}tt=\dfrac{80}{56}=\dfrac{10}{7}\left(mol\right)\)
Theo Pt: \(n_{CO_2}tt=n_{CaO}tt=\dfrac{10}{7}\left(mol\right)\)
\(\Rightarrow V_{CO_2}tt=\dfrac{10}{7}\times24=34,29\left(l\right)\)
