Which is classified as a type of acid-base reaction that produces a salt?

A. Combination

B. Decomposition

C. Hydrolysis

D. Neutralization

Answer Explanation:

A neutralization reaction is a type of acid-base reaction where an acid and base react to form a salt and water.

In an aqueous solution, a base increases the hydroxide concentration (OH–), while an acid increases the hydrogen ion (H+) concentration. Sometimes, neutralization reactions also occur. This type of reaction happens when an acid and a base react with each other to form water and salt. Salt is typically defined as an ionic compound that includes any cation except H+ and any anion except OH–. Consider the following example of a neutralization reaction between hydrobromic acid (HBr) and potassium hydroxide (KOH).

HBr+KOH→KBr+H2O

Not all neutralization reactions proceed in the manner where all reactants are in the aqueous phase. In some chemical reactions, one reactant may be a solid. The neutralization reaction can still proceed to completion.

Therefore, the Correct Answer is D.

Q #1: Fertilization (the fusing of one sperm and an ovum) results in a(n) _____.

A. embryo

B. fetus

C. infant

D. zygote

Answer Explanation

Human intercourse consists of the male introducing sperm into the female’s reproductive system. Sperm may then pass through the female’s reproductive system to the Fallopian tubes where one sperm fertilizes an ovum, creating a zygote. The zygote passes out of the Fallopian tube and implants into the uterine wall to begin gestation. Over nine months, the zygote develops and grows into an embryo and then a fetus. An infant is the baby that is born.
Q #2: After food has been masticated in the oral cavity, where does it go next?

A. Colon

B. Liver

C. Pancreas

D. Pharynx

Answer Explanation

Once the food has been masticated in the oral cavity (mouth), it is then swallowed and travels back into the pharynx down into the esophagus, which leads into the stomach.
Q #3: Which of the following atoms is a cation?

A. 14 protons, 14 neutrons, 18 electrons

B. 34 protons, 45 neutrons, 36 electrons

C. 35 protons, 44 neutrons, 35 electrons

D. 82 protons, 125 neutrons, 78 electrons

Answer Explanation

Because it has more protons than electrons, this atom has a positive charge and can be classified as a cation. When a metal such as sodium reacts to become stable, it loses its valence electrons. At first, it is a neutral atom with 11 protons and 11 electrons. When it loses an electron, the number of protons does not change, and the atom has 11 protons and 10 electrons. Because there is one more positively charged proton, a cation forms. A cation is an ion with a net positive charge.
