Question

hoàn trình phương trình phản ứng theo sơ đồ sau:

1, C_nH_2n+2+O₂ =>CO₂+H₂O

2, Cu+HNO₃=>Cu(NO₃)₂+NO₂+H₂O

3, C_xH_yO_z+O₂=>CO₂+H₂O

Answer 1

C_nH_2n+2 + \(\dfrac{3n+1}{2}\)O₂ \(\underrightarrow{t^o}\) nCO₂ + (n+1)H₂O

CuNO₃ + 4HNO₃ \(\rightarrow\) Cu(NO₃)₂ + 2NO₂ + 2H₂O

C_xH_yO_z + \(x+\dfrac{y}{4}-\dfrac{z}{2}\)O₂ \(\underrightarrow{t^o}\) xCO₂ + \(\dfrac{y}{2}\)H₂O

Answer 2

1 C_nH_2n+2 + 3n+1/ 2 O₂ __> n CO₂ + ( n + 1 ) H₂O

2 . 3Cu + 8HNO₃ ___> 3Cu(NO₃) + 4NO₂ + 2 H₂O

3. C_xH_yO_z + ( x+y/4 - z/2) O₂ ___> xCO₂ + y/2 H₂O
