$n_{Fe2O3}$ = $\frac{24}{160}$ = 0,15(mol)
PTHH :Fe2O3 + 3CO -> 2Fe+ 3CO2↑
Theo PTHH : nCO = 0,15 . 3 =0,45(mol)
Thể tích CO : 0,45 . 22,4 =10,08(l)
Đáp án:
\({V_{CO}} = 10,08l\)
Giải thích các bước giải:
\(\begin{array}{l}F{e_2}{O_3} + 3CO \to 2Fe + 3C{O_2}\\{n_{F{e_2}{O_3}}} = \dfrac{{24}}{{160}} = 0,15mol\\{n_{CO}} = 3{n_{F{e_2}{O_3}}} = 0,45mol\\{V_{CO}} = 0,45 \times 22,4 = 10,08l\end{array}\)
Em sẽ vote 5 sao cho ai làm đúng ạ , cảm ơn .
