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: Which acid is needed to make ammonium nitrate?

A. Sulfuric acid

B. Hydrochloric acid

C. Nitric acid

D. Acetic acid

Answer Explanation

A) Sulfuric acid: Sulfuric acid is not used in the production of ammonium nitrate. Although sulfuric acid is a widely used acid in various industries, it is not involved in the synthesis of ammonium nitrate.

B) Hydrochloric acid: Hydrochloric acid is not used in the production of ammonium nitrate. While it is an important industrial acid, it does not react with ammonia to produce ammonium nitrate.

C) Nitric acid (Correct Answer): Ammonium nitrate is typically produced by reacting ammonia (NH3) with nitric acid (HNO3). The reaction forms ammonium nitrate (NH4NO3), which is a common fertilizer and explosive compound.

D) Acetic acid: Acetic acid, commonly known as vinegar, is not used in the production of ammonium nitrate. It is a weak acid and does not react with ammonia to form ammonium nitrate.
Q #3: When acids and bases react together, we call this a:

A. Neutralization reaction.

B. Decomposition reaction.

C. Synthesis reaction.

D. Redox reaction.

Answer Explanation

A. Neutralization reaction. (Correct Answer): When acids and bases react, they undergo a neutralization reaction, resulting in the formation of water and a salt. In this reaction, the acidic properties of the acid are neutralized by the basic properties of the base.

B. Decomposition reaction: A decomposition reaction involves the breakdown of a compound into smaller substances. It does not typically describe the reaction between acids and bases.

C. Synthesis reaction: A synthesis reaction involves the formation of a compound from simpler substances. It does not typically describe the reaction between acids and bases.

D. Redox reaction: A redox reaction involves the transfer of electrons between reactants. While redox reactions can occur in certain acid-base reactions, they are not specific to the reaction between acids and bases. The typical reaction between acids and bases involves proton transfer rather than electron transfer. Therefore, "neutralization reaction" is a more specific and accurate term for this type of reaction.
