Question

1. A 1.0-gram sample of powdered Zn reacts faster with HCl than a single 1.0-gram piece of Zn because
the surface atoms in powdered Zn have
(1) higher average kinetic energy
(2) lower average kinetic energy
(3) more contact with the H+ ions in the acid
(4) less contact with the H+ ions in the acid

Answer 1

Answer:4

Explanatin: I think its 4 because their is less to contact.

Answer 2

A 1.0-gram sample of powdered Zn reacts faster with HCl than a single 1.0-gram piece of Zn because the surface atoms in powdered Zn have more contact with the H⁺ ions in the acid.

Hence, Option (C) is correct answer.

What is Zinc ?

Zinc is a chemical element. The atomic number of Zinc is 30. Zinc belongs to period 4 and group 12 in the periodic table. Zinc is a transition metal.

What is HCl ?

HCl is Hydrochloric acid. It is a nonflammable gas. Hydrochloric acid is also called muriatic acid. It is a strong corrosive acid. HCl is also known as hydrogen chloride.

Thus from the above conclusion we can say that A 1.0-gram sample of powdered Zn reacts faster with HCl than a single 1.0-gram piece of Zn because the surface atoms in powdered Zn have more contact with the H⁺ ions in the acid.

Hence, Option (C) is correct answer.
