Sample questions with answers
1. An example of a noble gas is
- A. chlorine
- B. neon.
- C. nitrogen.
- D. oxygen.
Answer: B. neon.
The noble gases, also known as the inert gases and aerogens, are the elements that belong to group 18 of the modern periodic table. The elements that belong to this group are:
1. Helium (He)
2. Neon (Ne)
3. Argon (Ar)
4. Krypton (Kr)
5. Xenon (Xe)
6. Radon (Rn)
They are known to possess extremely low chemical reactivity (hence the name inert gas). This is because all the noble gases have stable electronic configurations. This is the reason why noble gases do not form molecules easily and are mostly found as mono-atomic gases.

- A. epididymis.
- B. scrotal disc.
- C. sperm duct.
- D. testes.
Answer: A. epididymis.
Answer: A. Sperms are stored temporarily in the epididymis.

3. Which of the following properties of alcohol as a thermometric liquid is correct?
- A. It is opaque.
- B. It does not wet glass.
- C. It has a very flow freezing point.
- D. It has a high freezing point.
Answer: C. It has a very flow freezing point.
Answer: C. Alcohol has a very low freezing point (−115 °C), so it works in very cold places.
Answer: C. Alcohol has a very low freezing point (−115 °C), so it works in very cold places.
