Question

Chọn hệ số thích hợp

(giải thích cho mình hiểu nha)

a) NxOy + Cu ----- CuO + N2

b) FexOy + H2 ------- Fe + H2O

c) CxHyOz + O2 ------- Co2 + H2O

Answer 1

a)2NxOy + 2yCu ----- 2yCuO + yN2

b) FexOy + yH2 ------- xFe + yH2O

c) CxHyOz + \(\left(x+\frac{y}{4}-\frac{z}{2}\right)\)O2 ------- xCo2 +\(\frac{y}{2}\) H2O

Answer 2

\(\text{a)2NxOy+2yCu->2yCuO+xN2}\)

\(\text{b) FexOy+yH2->xFe+yH2O}\)

\(\text{c) 2CxHyOz(2x+y/2-z)O2->2xCO2+yH2O }\)

Answer 3

a) \(2N_xO_y+2yCu\rightarrow2yCuO+xN_2\)
b) \(Fe_xO_y+yH_2\rightarrow xFe+yH_2O\)

c) \(2C_xH_yO_z+\frac{4x+y-2z}{2}O_2\rightarrow2xCO_2+yH_2O\)
