Types of chemical reactionsPlease tell me what kind of chemical reactions are the following: Cu (s) + 4HNO3 (aq) → Cu(NO3)2 (aq) +NO2 (g) +H2O...

The following chemical reactions
are:

1. Substitution reaction. Also can be looked at as a
reduction reaction.

2. Double replacement reaction (or
Metathesis)

3. Acid-Base neutralization reaction (type of
double replacement reaction)

4. Chemical decomposition
reaction

5. Again, another Acid-Base neutralization
reaction (similar to 3)

6. Single replacement reaction (or
Substitution reaction)

Hope this
helps!
