How many moles of chlorine gas are contained in 9.02×10^23

Answers

Answer 1

Answer: 1 mole ----------- 6.02x10²³ molecules
? ----------- 9.02x10²³ molecules

9.02x10²³ * 1 / 6.02x10²³

9.02x10²³ / 6.02x10²³

= 1.4983 moles

hope this helps!

Which substance represents a compound?(1) C(s) (3) CO(g)(2) Co(s) (4) O2(g)

Answers

The substance that represents a compound among the given options is CO. The correct answer is (3) CO(g)

From the question,

We are to determine which of the given substances is a compound.

First, we will define a compound

A compound is a chemical species that is formed when two or more atoms join together chemically, with covalent or ionic bonds.

A compound is a substance that contains atoms of two or more different elements, and these atoms are chemically joined together

NOTE: A molecule consisting of atoms of only one element is NOT a compound.

Among the given options, only CO satisfies the definition of a compound, because it contains two different elements, Carbon (C) and Oxygen (O).

Hence, the substance that represents a compound among the given options is CO. The correct answer is (3) CO(g)

C = Carbon
CO = Carbon Monoxide
Co = Cobalt
O2 = Oxygen

So the answer is (3) CO
