a. an acid–base reaction
b. a metathesis reaction
c. a redox reaction
d. a precipitation reaction

검증된 단계별 안내
1
Understand the types of reactions: An acid-base reaction involves the transfer of protons (H+), a metathesis reaction involves the exchange of ions between two compounds, a redox reaction involves the transfer of electrons, and a precipitation reaction results in the formation of an insoluble solid.
Identify the reactants and products: The given reaction is N2(g) + 3H2(g) ⟶ 2NH3(g).
Analyze the reaction: This reaction involves the combination of nitrogen gas (N2) and hydrogen gas (H2) to form ammonia (NH3).
Determine the type of reaction: Since this reaction involves the combination of elements to form a compound, it is a synthesis reaction.
Relate synthesis to redox: In synthesis reactions like this one, elements are often oxidized and reduced, indicating a redox process.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Types of Chemical Reactions

Chemical reactions can be classified into several types, including synthesis, decomposition, single replacement, double replacement (metathesis), acid-base, redox, and precipitation reactions. Understanding these categories helps in identifying the nature of a given reaction based on the reactants and products involved.

Synthesis Reaction

A synthesis reaction, also known as a combination reaction, occurs when two or more reactants combine to form a single product. The reaction N2(g) + 3H2(g) ⟶ 2NH3(g) is an example of a synthesis reaction, as nitrogen and hydrogen gases combine to produce ammonia.

Redox Reactions

Redox (reduction-oxidation) reactions involve the transfer of electrons between species, resulting in changes in oxidation states. In the given reaction, there is no change in oxidation states of nitrogen or hydrogen, indicating that it is not a redox reaction, which is crucial for correctly identifying the type of reaction.

You are presented with a white solid and told that due to careless labeling it is not clear if the substance is barium chloride, lead chloride, or zinc chloride. When you transfer the solid to a beaker and add water, the solid dissolves to give a clear solution. Next an Na2SO41aq2 solution is added and a white precipitate forms. What is the identity of the unknown white solid?
