Question

The answer choices are as follows A: argon (Ar), B: fluorine (F2) or C: Oxygen (O2).

Answer 1

Oxygen. Option C is correct

Explanations:

The element given from the table below is Argon, Flourine, Hydrochloric acid, and Oxygen.

We are to detect the elements that possess the given property

• A ,colorless gas ,(the colorless gas are Argon, HCl, and Oxygen)

,

• Density, between 1.30g/L and 1.60g/L (Fluorine, HCl,, and Oxygen)

,

• The b,oiling point, is between -180 and -190 degrees celcius (Argon, Fluorine, and Oxygen)

,

• The gas reacted with sodium metal. The ,gas, that can ,react with sodium, is Flourine, Hydrochloric acid, and Oxygen

Since Oxygen is the only element that possesseses all the properties, hence the most likely identity of the gas is Oxygen.
