the test tube which holds the zinc becomes hot , the zinc turns into zinc chloride and hydrogen gas is produced. It is a chemical change.
When sulphuric acid is added to zinc granules , the gas produced is hydrogen gas. Zinc displaces hydrogen from sulphuric acid.
When dilute sulfuric acid is added to zinc granules, a displacement reaction takes place, resulting in the formation of zinc sulfate and hydrogen gas. This reaction is exothermic, which means it releases heat energy.
When copper oxide is added into excess dilute sulphuric acid, it reacts to form copper sulfate and water. Additionally, hydrogen gas is evolved during the reaction.
When dilute sulphuric acid is added to copper oxide, a chemical reaction occurs, resulting in the formation of copper sulfate and water. The reaction can be represented by the equation: CuO + H2SO4 → CuSO4 + H2O.
When silver metal is added to dilute sulphuric acid solution, a redox reaction takes place. The silver metal reacts with the sulfuric acid to produce silver sulfate and hydrogen gas. The reaction can be represented by the following equation: 2Ag(s) + H2SO4(aq) -> Ag2SO4(aq) + H2(g)

coz when we dilute zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2. the presence of hydrogen gas can be tested by bringing a naked flame to the mouth of the test tube. Hydrogen gas burns with a pop sound.
When dilute sulfuric acid is added to zinc, a chemical reaction occurs in which zinc reacts with the sulfuric acid to form zinc sulfate and hydrogen gas. The hydrogen gas is released as bubbles, and the zinc sulfate remains dissolved in the solution.
Iron + sulphuric acid ----> iron sulphate + hydrogen
Yes
Oxygen has a negligible effect on pH, likewise pure sulfur. However ... Sulfa oxides added to water form sulphuric acid, a major contributor to acidic oceans.
