Which of the following statements is false? Check all that apply. Gases are far more compressible than liquids The volume occupi
Sergio039 [100]

Answer:

The false statement is: 3. Because liquid water and liquid carbon tetrachloride do not mix, neither do their vapors

Explanation:

Gas is a state of matter, that has <u>less density than liquids and solids</u>. The gaseous particles have low intermolecular forces and thus they can move freely.

It is a very <u>compressible fluid</u> that has no fixed shape. Gas occupies the whole container in which it is stored, thus taking the shape of the container. Therefore, <u>the volume of the gas is equal to the volume of the container.</u>

<u>Polar liquid like water (H₂O) and nonpolar liquid like carbon tetrachloride, are immiscible. However, in the gaseous state, their vapors form a  homogeneous mixture.</u>

MatroZZZ [7]

<em>It is beneficial because it provides stronger support for the evidence related to the discovery</em>

<u>Answer:</u> <em>The correct answer is the second option that is given with shows it is beneficial.</em>

<u>Explanation:</u>

The discovery of an element whose properties are known from before would make it easier for the scientists to know the properties of elements and its uses after the discovery of element.

Since the elements’ properties are already known as element that possesses these properties and will look forward to find that and once the element is found the element can be named and can be used directly, since its uses are already known.
