Chemistry Class 9th MCQs: questions and answer review

Try each question before opening its answer. Record the concept behind each mistake and revisit it during your next practice session.

91. The vapour pressure of a liquid increases with the _______?

مائع کا بخارات کا دباؤ ______ کے ساتھ بڑھتا ہے؟

Check answer and explanation

Answer: Increase of temperature

Explanation Vapor pressure is the pressure exerted by the vapor of a liquid in equilibrium with its solid or liquid phase. As temperature increases, the molecules of a liquid gain kinetic energy and move more rapidly. Increasing the number of molecules that escape into the vapor phase, thereby increasing the vapor pressure.

92. Non-metals of ____ group are gases.

گروپ کی غیر دھاتیں گیسیں ہیں۔ _____

Check answer and explanation

Answer: VIII-A

Explanation Group VIII-A, also known as the noble gases , consists of: Helium (He) Neon (Ne) Argon (Ar) Krypton (Kr) Xenon (Xe) Radon (Rn)

93. When one atom forms cation by losing electron and other forms anion by accepting that electron then bond form between them is ______?

Check answer and explanation

Answer: Ionic bond

Explanation When one atom loses an electron to form a cation and another atom gains that electron to form an anion, the resulting attraction between the oppositely charged ions is an ionic bond. This type of bond is typically formed between a metal and a nonmetal, and is characterized by a transfer of electrons rather than a sharing of electrons (as in covalent bonds).

94. Which one of the following is Metalloid?

مندرجہ ذیل میں سے کون سا میٹالائیڈ ہے؟

Check answer and explanation

Answer: Se

Explanation Selenium (Se) is a metalloid , which means it exhibits some properties of metals and some properties of nonmetals. Metalloids are elements that are intermediate in character between metals and nonmetals.

95. In an atom number of protons and neutrons are added to obtain ________?

ایٹم میں پروٹان اور نیوٹران کی تعداد ________ حاصل کرنے کے لیے شامل کی جاتی ہے؟

Check answer and explanation

Answer: Number of nucleons

Explanation The number of protons and neutrons in an atom are added together to obtain the total number of nucleons. It is also known as the mass number.
