​

Answer 1

Answer:

little test in chemistry to cover what we have done over the 4 or 5 weeks we have been at school and It was all fine expect for one question which I spent around 10 minutes on and still could not answer. The question was to balance this:

Cu + HNO3 = Cu(NO3)2 + NO + H2O

Since the exam I have looked up the solution on-line and discovered that the answer is:

3Cu+ 8HNO3----> 3Cu(NO3)2 + 2NO +4H2O
