The reaction of copper pennies (pre 1983) is a very intense exothermic reaction. The copper is oxidized by the acid.
Nitric acid (HNO3) and copper(II) sulfate (CuSO4) will react in a double replacement reaction to produce copper(II) nitrate and sulfuric acid. The correctly balanced equation is: 2HNO3 + CuSO4 --> Cu(NO3)2 + H2SO4
Gold and platinum will no react with HNO3 due to their low reactivity. Aluminum also will not react with HNO3 despite its relatively high reactivity because it has a protective layer of aluminum oxide on it.
Acids known to dissolve copper include hydrochloric acid (HCl), nitric acid (HNO3), and sulfuric acid (H2SO4). These acids can react with copper to form soluble copper compounds, allowing the metal to dissolve.
Copper reacts with nitric acid because it is a stronger oxidizing agent compared to hydrochloric acid. Nitric acid can easily oxidize copper to form copper(II) ions, while HCl lacks this oxidizing capability and therefore does not react with copper.
The balanced chemical equation for the reaction between copper (Cu) and nitric acid (HNO3) is Cu + 4HNO3 -> Cu(NO3)2 + 2NO2 + 2H2O. From the equation, it can be seen that 1 mol of Cu reacts with 4 mol of HNO3. Therefore, to react with 2.0 mol of HNO3, 0.5 mol of Cu is needed. The molar mass of Cu is approximately 63.5 g/mol, so 0.5 mol of Cu would be equivalent to 31.75 grams.

The balanced chemical equation for the reaction between copper (Cu) and nitric acid (HNO3) is: 3Cu + 8HNO3 -> 3Cu(NO3)2 + 2NO + 4H2O According to the equation, 8 moles of HNO3 are required to react with 3 moles of Cu. Therefore, to react with 6 moles of Cu, you would need 16 moles of HNO3.
No. HNO3 already has hydrogen and nitrogen in their highest possible oxidation states.
Gold and platinum will no react with HNO3 due to their low reactivity. Aluminum also will not react with HNO3 despite its relatively high reactivity because it has a protective layer of aluminum oxide on it.

Copper does not react with nitrogen under normal conditions. However, at very high temperatures and pressures, copper can react with nitrogen to form copper nitride.
Copper doesn't react wih alkalis.
Nitric acid (HNO3) and calcium hydroxide (Ca[OH]2) react to form calcium nitrate (Ca[NO3]2) and water (H2O).
When AlCl3 reacts with HNO3, the products are Al(NO3)3 and HCl. When AlCl3 reacts with AgNO3, the products are AgCl and Al(NO3)3.
Copper does not react in water.
