You are given the reaction Cu + HNO3 → Cu(NO3)2 + NO + H2O.

Half reactions:

3Cu -> 3Cu2+ + 6e-

2N5+ +6e- -> 2N2+

Complete the final balanced equation based on the half-reactions.

__Cu + __HNO3 -> __Cu(No3)2 + __NO + __H2O

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?
