Predict what would be observed (and why) from an aqueous mixture for each of the following solution (all substances are water soluble).

See explanation.

Explanation:

Hello,

In this case, after looking for the information, the four cases and their discussion are:

a. Potassium carbonate and hydrochloric acid : in this case, the chemical reaction is:

Aqueous potassium chloride and water are formed and carbon dioxide is given off as gas due to the instability of the carbonic acid.

b. Zinc chloride and silver nitrate : in this case, the chemical reaction is:

Aqueous silver nitrate is formed and solid silver chloride is precipitated out due to its low solubility in water.

c. Magnesium chloride and sodium hydroxide : in this case, the chemical reaction is:

Aqueous sodium chloride is formed and solid magnesium hydroxide is precipitated out due to its low solubility in water.

d. Ammonium nitrate and sodium hydroxide: in this case, the chemical reaction is:

Sodium nitrate becomes aqueous as liquid water is formed and ammonia is given off as a gas due to the instability of the ammonium hydroxide.

Best regards.

they are all solids.
