,1. A patient has a blood pH of 7.3. What does this
indicate?
a) Normal blood pH
b) Acidosis
c) Alkalosis
d) Neutral condition
Answer: b) Acidosis
Rationale: Normal blood pH ranges from 7.35 to 7.45.
A pH of 7.3 indicates acidosis, meaning the blood is slightly
more acidic than normal.
2. Which element is most likely to form an ion with a -2
charge in chemical reactions?
a) Magnesium
b) Sulfur
c) Aluminum
d) Potassium
Answer: b) Sulfur
Rationale: Sulfur, belonging to Group 16, typically gains
two electrons to achieve a stable electron configuration,
forming a -2 charge ion.
3. When a piece of metal is heated and then submerged in
cool water, what is the primary form of heat transfer
between the metal and the water?
a) Radiation

, b) Conduction
c) Convection
d) Sublimation
Answer: b) Conduction
Rationale: The metal transfers heat to the water
through direct contact, which is conduction.
4. What type of reaction occurs when an acid reacts with a
base to produce a salt and water?
a) Synthesis
b) Decomposition
c) Single replacement
d) Neutralization
Answer: d) Neutralization
Rationale: An acid and a base reacting to form a salt
and water is known as a neutralization reaction.
5. Which of the following has the highest ionization
energy?
a) Sodium
b) Aluminum
c) Chlorine
d) Argon
Answer: d) Argon
Rationale: Argon, a noble gas, has a complete valence
electron shell, resulting in a high ionization energy.
