\(PTHH:Fe_2O_3+3CO\rightarrow2Fe+3CO_2\uparrow\)
Áp dụng ĐLBTKL ta có:
\(m_{Fe_2O_3}+m_{CO}=m_{Fe}+m_{CO_2}\)
\(\Rightarrow m_{Fe}=m_{Fe_2O_3}+m_{CO}-m_{CO_2}=16,8+32-26,4=22,4\left(kg\right)\)
3CO + Fe2O3 \(\underrightarrow{to}\) 2Fe + 3CO2
Theo ĐL BTKL ta có:
\(m_{CO}+m_{Fe_2O_3}=m_{Fe}+m_{CO_2}\)
\(\Leftrightarrow16,8+32=m_{Fe}+26,4\)
\(\Leftrightarrow48,8=m_{Fe}+26,4\)
\(\Leftrightarrow m_{Fe}=22,4\left(kg\right)\)
