The correct answer choice which best describes why a liquid needs a container when a solid does not is simply because:
Solids have definite shapes, and liquids fill their containers.
Matter is classified as element, compounds and mixtures
<h3>What is an element?</h3>
An element is a substance which cannot be split into simpler forms by an ordinary chemical process. This simply goes to say that elements are substances which cannot be decomposed into simpler substances by ordinary chemical reactions.
An atom is the smallest unit or part of an element which can take part in a chemical reaction.
On a general note, elements are classified as thus:
- Metals, non-metal, and metalloid.
- The extreme left side elements in the periodic table are metals, for example, aluminum, sodium, calcium, caesium, etc.
- However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen,
So therefore, the correct answer choice which best describes why a liquid needs a container when a solid does not is simply because:
Solids have definite shapes, and liquids fill their containers.

Answer:
Explanation:
Hello,
In this case, since the molarity is defined as the ratio of the moles of the solute to the volume of the solution in liters:
For the given volume and molarity, we solve for the moles of ammonium sulfate (solute) as shown below:

D) conduct electricity in water.
Explanation:
Both acids and bases conducts electricity in water.
When acid dissolves in water, they are good electrolytes.
When bases dissolves in water they are good electrolytes.
- Electrolytes are liquid or molten substances that are able to conduct electricity.
- they conduct electricity by the use of their ions in solution.
- Since acid and bases ionize in solution, they will conduct electricity.
An acid is a substance that produces excess hydroxonium ion in solution.
A base produces excess hydroxyl ions in solution
