Crystalline/solid boron does not react at all with sulfuric acid. However, finely powered boron will react with sulfuric acid but very slowly.
Boron is resistant to boiling HF or HCl. However, in finely divided state, it reacts slowly with hot conc. nitric acid, sulphuric acid & mixture of sulphuric acid & chromic acid.

Copper Oxide reacts with Sulphuric acid to form Copper Sulphate and Water.
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.
When boron reacts with concentrated sulfuric acid, it forms boron trioxide (B2O3) and sulfur dioxide (SO2) as products. The reaction is characterized by the formation of a white, powdery solid of boron oxide, along with the release of heat. Additionally, concentrated sulfuric acid acts as an oxidizing agent, facilitating the oxidation of boron during the reaction.
When copper reacts with sulphuric acid, copper sulfate is formed. This reaction involves the displacement of hydrogen in sulphuric acid by copper, resulting in the formation of copper sulfate and hydrogen gas.
Nickel forms Hydrogen gas when reacts with dilute acid.

H2SO4 + CaCO3 ---> CaSO4 + H2O + CO2 Sulphuric acid reacts with calcium carbonate, forming calcium sulphate.
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.
