Acid indigestion is sometimes neutralized with an antacid such as magnesium hydroxide (Mg(OH)2). What products will be released
Lunna [17]

Answer: d) MgCl_2 and H_2O​

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

A neutralization reaction is a double displacement reaction in which an acid reacts with base to produce salt and water. The H^+ ions from water reacts with OH^- ions from base to give water.

2HCl+Mg(OH)_2\rightarrow MgCl_2+2H_2O

Thus products that will be released when the antacid is mixed with the hydrochloric acid in the stomach are MgCl_2 and H_2O​

Describe some acidic oxides that can be prepared by thermal decomposition of nitrates and carbonates
azamat

When calcium carbonate is heated, it breaks down to form calcium oxide and carbon dioxide.

Thermal decomposition is the process in which heat is required.

It is also known as thermolysis.

It is processed in which a compound breaks into two or more products when the heat is supplied.

This reaction is used for the production of oxygen.

This reaction is also used for production of acidic as well as basic oxides.

CaCO3 on thermal decomposition gives:

CaCO3→CaO+CO2

CaO→ Basic oxide.

CO2→ Acidic oxide.
