What is produced when an acid reacts with a metal carbonate or metal hydrogen carbonate?

A. Salt and water

B. Carbon dioxide and water

C. Oxygen gas and water

D. Salt and hydrogen gas

Answer Explanation:

A) Salt and water: This reaction occurs when an acid reacts with a metal hydroxide or a metal oxide, not with a metal carbonate or metal hydrogen carbonate.

B) Carbon dioxide and water (Correct Answer): When an acid reacts with a metal carbonate or metal hydrogen carbonate, carbon dioxide gas is produced along with water and a salt. The carbonates decompose into carbon dioxide gas, water, and a salt when reacting with acids.

C) Oxygen gas and water: This reaction is not typical when an acid reacts with a metal carbonate or metal hydrogen carbonate. Metal carbonates and metal hydrogen carbonates generally do not produce oxygen gas when reacting with acids.

D) Salt and hydrogen gas: This reaction occurs when an acid reacts with a metal, not with a metal carbonate or metal hydrogen carbonate. When metals react with acids, hydrogen gas is typically produced along with a salt.

Therefore, the Correct Answer is B.

Q #1: What is produced when an acid reacts with a metal?

A. Salt and water

B. Carbon dioxide and water

C. Oxygen gas and water

D. Salt and hydrogen

Answer Explanation

A) Salt and water: This reaction occurs when an acid reacts with a metal hydroxide or a metal oxide. When metals react with acids, hydrogen gas is typically produced along with a salt, not water.

B) Carbon dioxide and water: This reaction occurs when an acid reacts with a metal carbonate, not a metal. When carbonates react with acids, carbon dioxide gas is produced along with water and a salt.

C) Oxygen gas and water: This reaction is not typical when an acid reacts with a metal. Metal reactions with acids usually produce hydrogen gas along with a salt.

D) Salt and hydrogen (Correct Answer): When an acid reacts with a metal, hydrogen gas is produced along with a salt. The metal displaces hydrogen ions from the acid, forming a salt, while hydrogen gas is released as a byproduct of the reaction.
Q #2: What is produced when an acid reacts with a metal carbonate or metal hydrogen carbonate?

A. Salt and water

B. Carbon dioxide and water

C. Oxygen gas and water

D. Salt and hydrogen gas

Answer Explanation

A) Salt and water: This reaction occurs when an acid reacts with a metal hydroxide or a metal oxide, not with a metal carbonate or metal hydrogen carbonate.

B) Carbon dioxide and water (Correct Answer): When an acid reacts with a metal carbonate or metal hydrogen carbonate, carbon dioxide gas is produced along with water and a salt. The carbonates decompose into carbon dioxide gas, water, and a salt when reacting with acids.

C) Oxygen gas and water: This reaction is not typical when an acid reacts with a metal carbonate or metal hydrogen carbonate. Metal carbonates and metal hydrogen carbonates generally do not produce oxygen gas when reacting with acids.

D) Salt and hydrogen gas: This reaction occurs when an acid reacts with a metal, not with a metal carbonate or metal hydrogen carbonate. When metals react with acids, hydrogen gas is typically produced along with a salt.
Q #3: What is produced when an acid reacts with ammonia?

A. Water

B. Ammonia and Water

C. Ammonium salt

D. Hydrogen gas

Answer Explanation

A) Water: Water is not typically produced when an acid reacts with ammonia. Water may be present in the reaction mixture, but it is not a direct product of the reaction between the acid and ammonia.

B) Ammonium chloride: Water and ammonia are not typically produced when an acid reacts with ammonia.

C) Ammonium salt (Correct Answer): When an acid reacts with ammonia, an ammonium salt is typically formed. The specific ammonium salt produced depends on the acid used in the reaction.

D) Hydrogen gas: Hydrogen gas is not typically produced when an acid reacts with ammonia. The reaction between an acid and ammonia does not involve the liberation of hydrogen gas.
