(4)汽车尾气中常含有D和CO,二者在催化剂作用下可以大部分转化为两种对空气无污染的物质,已知:F(g) + A(g) =" 2D" (g) ;△H =" +180.5KJ/mol"

2C (s)+ O2 (g)=" 2CO(g)" ;△H =" -221.0" KJ/mol

C (s)+ O2(g) = CO2(g);△H =" -393.5" KJ/mol

则上述尾气转化的热化学方程式为:                         

答案

(1)NH3;(略)

(2)3CuO + 2NH33Cu + N2 +3H2O(加热)

(3) 3Cu +8H+ + 2NO3- = 3Cu2+ + 2NO + 4H2O   6e-

(4)2NO(g)+2CO(g) N2(g)+2CO2(g);△H= —746.5KJ/mol
