Question

Cân bằng các PTHH sau:

Fe + HNO3 -----> Fe(NO3)3 + N2 + H2O

Mg + HNO3-----> Mg(NO3)2 + NO + H2O

FexOy + H2 -----> FeO + H2O

CxHyOz + O2 -----> CO2 + H2O

nguyen an · Accepted Answer

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 + $\dfrac{y}{2}$H2OCâu trả lời: 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

Hồ Hữu Phước · Answer

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

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

FexOy+(y-x)H2$\rightarrow$xFeO+(y-x)H2O

CxHyOz+($x+\dfrac{y}{4}-\dfrac{z}{2}$)O2$\rightarrow$xCO2+$\dfrac{y}{2}H_2O$Câu trả lời: 10Fe+36HNO3$\rightarrow$10Fe(NO3)3+3N2+18H2O

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

FexOy+(y-x)H2$\rightarrow$xFeO+(y-x)H2O

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

Nguyen · Answer

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
