Question

Cân bằng các PTHH sau :
Fe_xO_y + CO -----> FeO + CO₂
C_xH_y + O₂ -----> CO₂ + H₂O
Fe(OH)_2y/x + O₂ -----> Fe₂O₃ + H₂O
Fe_xO_y + H₂SO₄ -----> Fe₂(SO4)₃ + SO₂ + H₂O

Answer 1

\(Fe_xO_y+\left(y-x\right)CO\underrightarrow{t^o}xFeO+\left(y-x\right)CO_2\)

\(2C_xH_y+\dfrac{4x+y}{2}O_2\underrightarrow{t^o}2xCO_2+yH_2O\)

\(4xFe\left(OH\right)_{\dfrac{2y}{x}}+\left(3x-2y\right)O_2\underrightarrow{t^o}2xFe_2O_3+4yH_2O\)

\(2Fe_xO_y+\left(6x-2y\right)H_2SO_{4\left(đ\right)}\underrightarrow{t^o}xFe_2\left(SO_4\right)_3+\left(3x-2y\right)SO_2+\left(6x-2y\right)H_2O\)
