When hydrogen gas is passed through a solution of copper nitrate, a redox reaction occurs where the copper ion gains electrons to form solid copper metal. Nitrate ions are reduced to nitrogen oxides or nitrogen gas depending on the reaction conditions.
Sulfuric acid reacts with copper to produce copper sulfate. Copper sulfate is formed when copper reacts with sulfuric acid in the presence of oxygen.
Nitric acid reacts with metals, metal oxides, or metal carbonates to produce nitrate salts. The acid donates a hydrogen ion to form water and the metal or base component takes the remaining ion to form the nitrate salt.
If a copper is clean it doesn't react to acid, unless precisely if the acid is also an oxidising agent.It happens because copper is below hydrogen in the activities series. (will notice that this is not really an explanation, just an impressive way of saying that copper is not reactive enough to react with acids.) if any reason the copper surface has been oxidised, the copper oxide will dissolve in acid that's the only time it will react to acid. If the acid is strongly oxidising, the copper can dissolve to make a solution of the copper salt. For example, copper dissolves in concentrated nitric acid to give you nitrogen oxides and copper nitrate in solution, and also in hot concentrated sulphuric acid to give you sulphur dioxide and copper hydrogen-sulphate in solution.
When copper is added to silver nitrate, a redox reaction occurs where the copper displaces the silver in the compound, forming copper(II) nitrate and silver metal. This reaction is often used as a demonstration of displacement reactions in chemistry.

Sulfuric acid reacts with copper to produce copper sulfate. Copper sulfate is formed when copper reacts with sulfuric acid in the presence of oxygen.
Zn + HCl = ZnCl + H the will be hydrogen and it will make a squeaky pop noise

When copper is added to silver nitrate, a redox reaction occurs where the copper displaces the silver in the compound, forming copper(II) nitrate and silver metal. This reaction is often used as a demonstration of displacement reactions in chemistry.
When copper II hydroxide and sodium nitrate are heated together, they may undergo a decomposition reaction. Copper II hydroxide will decompose into copper II oxide and water, while sodium nitrate will decompose into sodium nitrite and oxygen.

When copper (II) nitrate and sodium hydroxide are mixed, a chemical reaction occurs, resulting in the formation of copper (II) hydroxide, which is insoluble in water. This insoluble compound precipitates out of the solution, appearing as a solid.
hydrogen S + H2 -------> H2S (HYDROGEN SULPHIDE)
When ammonium oxalate reacts with lead nitrate, insoluble lead oxalate is formed as a yellow precipitate. This reaction is a double displacement reaction where the cations switch partners to form the products.
Magnesium is a highly reactive metal compared to gold, silver and copper. It will form a magnesium oxide as an outer-shell when it comes to contact with oxygen in the air, and it reacts with water, creating hydrogen gas and fizzing.
