Milk of magnesia is a sparingly soluble suspension of magnesium hydroxide in water. it acts as an antacid by neutralizing hydrochloric acid (hcl) in the stomach. which is the best explanation of how milk of magnesia neutralizes the conjugate acid produced by hcl and h2o in the stomach

The milk of magnesia is a suspension of magnesium hydroxide in water, which is a strong base that is used to neutralize excess stomach acid. The presence of stomach acid or hydrochloric acid (HCl) that is known to be a strong acid will react with the strong base and neutralization reaction occurs since conjugate partners produced negligible strength where the products are a salt and water.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.
