Alkenes react with concentrated sulphuric acid in the cold to produce alkyl hydrogensulphates. Ethene reacts to give ethyl hydrogensulphate.
CH2=CH2 + H2SO4 --> CH3CH2OSO2OH
The structure of the product molecule is sometimes written as CH3CH2HSO4, but the version in the equation is better because it shows how all the atoms are linked up. You may also find it written as CH3CH2OSO3H.
Hexane does not react with concentrated sulphuric acid under normal conditions. However, if heated strongly, it may undergo dehydration to form alkenes.
Gold does not react with sulphuric acid under normal conditions. Gold is a noble metal and is resistant to corrosion by acids, including sulphuric acid.
When copper reacts with dilute sulphuric acid, copper sulfate and hydrogen gas are produced. The copper sulfate formed will be a blue solution. This reaction is a redox reaction, where copper is oxidized and hydrogen is reduced.
Sulphuric acid is an acid, so many substances react with it. It will be impractical to list down all the things that would react with sulphuric acid as there are enormously too many! Examples are metals, metal oxides and metal carbonates.
Ammonium sulphate is a fertiliser that can be made by the neutralisation reaction between Ammonia and Sulphuric acid
Hexane does not react with concentrated sulphuric acid under normal conditions. However, if heated strongly, it may undergo dehydration to form alkenes.
The remaining mixture of alkanes and alkenes is discarded into water to separate the alkenes from the alkanes because alkenes are soluble in sulfuric acid and can undergo electrophilic addition reactions, while alkanes do not react with sulfuric acid. Water helps to extract the alkenes, allowing for a clearer separation of the components. Furthermore, this process minimizes the risk of unwanted reactions and ensures that only the reactive alkenes interact with sulfuric acid.

These acids doesn't react; they are only mixed.

Boron does not react with sulfuric acid under normal conditions. Boron is relatively inert to sulfuric acid and does not readily form a reaction with it.
