A copper wire was dropped into the nitric acid in the beaker and the formation of copper (II) nitrate. The balanced equation for this reaction is:

Cu(s) + 4 HNO3(aq) ⇒ Cu(NO3)2(aq) + 2 NO2(g) + 2 H2O(l)

A) What is the balanced equations of the two reactions when: 2.0 g of 30-mesh zinc metal is added to the reaction beaker and reduces the copper (II) ion to copper metal and generate aqueous zinc (II) ion is generated.

B) What is the balanced equation of the separate (side) reaction that occurs in part A between some of the zinc metal and the sulfuric acid to form hydrogen gas?

C) What is the balanced equation when 5 mL of distilled water and 10 mL of concentrated hydrochloric acid is added to the reaction beaker? The acid will react with any excess zinc metal in the reaction mixture and will release hydrogen gas.

The zinc within a copper-plated penny will dissolve in hydrochloric acid if the copper coating is filed down in several spots (so that the hydrochloric acid can get to the zinc). The reaction between the acid and the zinc is as follows: 2H+(aq)+Zn(s)→H2(g)+Zn2+(aq). When the zinc in a certain penny dissolves, the total volume of gas collected over water at 25 ∘C was 0.959 L at a total pressure of 752 mmHg. What mass of hydrogen gas was collected?
