Reactions of Acids and Bases (with Metals, Carbonates, Each Other) MCQs

Q1. What happens when metals strike a hard surface? Do they produce a sound?

• A.Yes, all metals produce a sound
• B.No, metals do not produce a sound
• C.Yes, sonorous metals produce a sound
• D.It depends on the type of metal

Answer: C. Yes, sonorous metals produce a sound

What is the textbook's take? Yes, sonorous metals produce a sound. Does that line up with one of the options? Yes - The textbook states that metals that produce a sound on striking a hard surface are called sonorous. And the rest? option A) 'Yes, all metals produce a sound' is incorrect: The textbook states that only sonorous metals produce a sound; option B) 'No, metals do not produce a sound' fails since The textbook states that sonorous metals produce a sound. Pick: C) Yes, sonorous metals produce a sound.

Q2. Which statement about the melting point of the metal gallium is correct?

• A.Gallium has a very low melting point - it can melt in the warmth of your hand
• B.Gallium has a very high melting point, like tungsten
• C.Gallium does not melt at any temperature
• D.Gallium is a non-metal

Answer: A. Gallium has a very low melting point - it can melt in the warmth of your hand

Q3. Which statement about the melting point of the metal caesium is correct?

• B.Caesium has a very high melting point, like tungsten
• C.Caesium does not melt at any temperature
• D.Caesium is a non-metal

Answer: A. Caesium has a very low melting point (it melts only a little above room temperature)
