Question

Cân bằng các PTHH sau:

Fe + HNO₃ -----> Fe(NO₃)₃ + N₂ + H₂O

Mg + HNO₃-----> Mg(NO₃)₂ + NO + H₂O

Fe_xO_y + H₂ -----> FeO + H₂O

C_xH_yO_z + O₂ -----> CO₂ + H₂O

Answer 1

10Fe + 36HNO3 → 10Fe(NO3)3 + 3N2 + H2O

3Mg + 8HNO3 →3 Mg(NO3)2 +2NO+4 H2O

FexOy + (y-x)H2 → xFeO + (y-x)H2O

CxHyOz +( x +\(\dfrac{y}{4}\)-\(\dfrac{z}{2}\) )O2 → xCO2 + \(\dfrac{y}{2}\)H2O

Answer 2

10Fe+36HNO₃\(\rightarrow\)10Fe(NO₃)₃+3N₂+18H₂O

3Mg+8HNO₃\(\rightarrow\)3Mg(NO₃)₂+2NO+4H₂O

Fe_xO_y+(y-x)H₂\(\rightarrow\)xFeO+(y-x)H₂O

C_xH_yO_z+(\(x+\dfrac{y}{4}-\dfrac{z}{2}\))O₂\(\rightarrow\)xCO₂+\(\dfrac{y}{2}H_2O\)

Answer 3

10Fe + 36HNO3 → 10Fe(NO3)3 + 3N2 + H2O

3Mg + 8HNO3 →3 Mg(NO3)2 +2NO+4 H2O

FexOy + (y-x)H2 → xFeO + (y-x)H2O

CxHyOz +( x +y/4-z/2)O2 → xCO2 + y/2H2O
