CaCO3 \(\underrightarrow{to}\) CaO + CO2
\(m_{CaCO_3}=3000\times85\%=2550\left(kg\right)=2550000\left(g\right)\)
\(\Rightarrow n_{CaCO_3}=\frac{2550000}{100}=25500\left(mol\right)\)
\(\Rightarrow n_{CaCO_3}pư=25500\times90\%=22950\left(mol\right)\)
Theo pT: \(n_{CaO}tt=n_{CaCO_2}pư=22950\left(mol\right)\)
\(\Rightarrow m_{CaO}tt=22950\times56=1285200\left(g\right)=1285,2\left(kg\right)\)
Theo pT: \(n_{CO_2}tt=n_{CaCO_3}pư=22950\left(mol\right)\)
\(\Rightarrow m_{CO_2}=22950\times44=1009800\left(g\right)=1009,8\left(kg\right)\)
CaCO3--t0--> CaO + CO2
Ta có mCaCO3= 85.3000/100=2550kg=2 550 000
=> nCaCO3=2 550 000 /100=25 500
=> nCaO=nCO2=nCaCO3 PỨ = 90.25 500/100=22 950
=> mCaO=22 950 .56=1 285 200g=1285,2kg
mCO2=22 950 .44=1 009 800 g=1009,8 kg
mCaCO3 = 3000*85/100=2550 (kg)
mCaCO3 ( pư ) = 2550*90/100= 2295 (kg)
CaCO3 -to-> CaO + CO2
100_________56____44
2295________x_____y
=> x = 1285.2 kg
=> y = 1009.8 kg
