Identify each of the following reactions as a synthesis, decomposition, or exchange reaction:
2Hg + O₂ 2HgO
Fe²¹ + CuSO₄ → FeSO₄ + Cu²¹
HCl + NaOH → NaCl + H₂O
HNO₃ → H⁺ + NO₃⁻

Step 1: Understand the three types of chemical reactions. Synthesis reactions involve combining two or more reactants to form a single product. Decomposition reactions involve breaking down a compound into simpler substances. Exchange reactions involve swapping components between reactants to form new products.
Step 2: Analyze the first reaction: 2Hg + O₂ → 2HgO. Here, two reactants (Hg and O₂) combine to form a single product (HgO). This is characteristic of a synthesis reaction.
Step 3: Analyze the second reaction: Fe²¹ + CuSO₄ → FeSO₄ + Cu²¹. In this reaction, components are exchanged between the reactants (Fe²¹ and CuSO₄), resulting in new products (FeSO₄ and Cu²¹). This is an exchange reaction.
Step 4: Analyze the third reaction: HCl + NaOH → NaCl + H₂O. This reaction involves the exchange of ions between HCl and NaOH to form NaCl and H₂O. This is also an exchange reaction, specifically a neutralization reaction.
Step 5: Analyze the fourth reaction: HNO₃ → H⁺ + NO₃⁻. Here, a single compound (HNO₃) breaks down into two simpler substances (H⁺ and NO₃⁻). This is characteristic of a decomposition reaction.

주요 개념

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

Synthesis Reaction

A synthesis reaction, also known as a combination reaction, occurs when two or more reactants combine to form a single product. This type of reaction can be represented by the general equation A + B → AB. An example is the reaction of mercury and oxygen to form mercury oxide (2Hg + O₂ → 2HgO).

Decomposition Reaction

A decomposition reaction involves the breakdown of a single compound into two or more simpler products. This can be represented by the general equation AB → A + B. An example is the dissociation of nitric acid into hydrogen ions and nitrate ions (HNO₃ → H⁺ + NO₃⁻).

Exchange Reaction

An exchange reaction, also known as a double displacement reaction, occurs when parts of two compounds exchange places to form two new compounds. This can be represented by the general equation AB + CD → AD + CB. An example is the reaction between iron ions and copper sulfate, resulting in iron sulfate and copper (Fe²¹ + CuSO₄ → FeSO₄ + Cu²¹).

Mrs. Roberts, who is in a diabetic coma, has just been admitted to Noble Hospital. Her blood pH indicates that she is in severe acidosis (blood pH in the acid range), and the medical staff quickly institute measures to bring her blood pH back within normal limits. Note the normal pH of blood, and discuss why severe acidosis is a problem.
