50pts plz solve this if u spam then I will report​

Answer 1

Explanation:

a) Calcium carbonate reacts with acids to produce a calcium salt, water and carbon dioxide: calcium carbonate +hydrochloric acid → calcium chloride + water + carbon dioxide.

b)When hydrogen gas passed through boiling sulphur (at a high temperature) hydrogen sulphide gas with rotten egg like odour is formed

c) The concentrated sulphuric acid gives a hydrogen ion to the halide ion to produce a hydrogen halide. Because this is a gas, it immediately escapes from the system. ... As an example, concentrated sulphuric acid reacts with solid sodium chloride in the cold to produce hydrogen chloride and sodium hydrogensulphate.

d) Copper(II) oxide reacts with sulfuric acid. Black copper(II) oxide (CuO) reacts slowly with 1 M sulfuric acid (H2SO4) at room temperature, producing blue solution of copper(II) sulfate (CuSO4) and water: CuO + H2SO4 -> CuSO4 + H2O.

e)Sodium sulfite (NaSO3) and hydrochloric acid (HCl) are mixed to create sulfur dioxide gas (SO2), which is a common byproduct of industrial processes.

f) Magnesium reacts with hydrochloric acid according to the equation: Mg(s) + 2 HCl(aq) --> MgCl 2(aq) + H 2(g) This demonstration can be used to illustrate the characteristic reaction of metals with acid, a single replacement reaction, or to demonstrate the generation of hydrogen gas.|

g )Zinc sulphide dissolves in dilute hydrochloric acid forming zinc chloride.

hope it will help u

plz mark me as brainliest
