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:
True
Explanation:
Sometimes you will need to convert from grams to moles, or moles to grams
Answer:
A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.
Hope this is what you mean be hot spot!
I hope this helps you!

Answer:
First-order with respect to hydrogen.
Explanation:
Hello!
In this case, considering that the rate law of this reaction can be expressed via:
If we want to know m, the order of reaction with respect to hydrogen, we need to relate the experiments 1 and 3 in order to get rid of the pressure of ICl:
Thus, we plug in the given rates, and pressures to get:
So we can cancel wout k and 325^n:
Next we solve for m, the order of reaction with respect to hydrogen:
It means it is first-order with respect to hydrogen.

Answer: Option D) Saturated
Explanation:
A solution is said to be saturated when it contains as much solute as it can dissolve at that temperature. Hence, if more solute is added, it will not dissolve.
Thus, a saturated solution has the maximum amount of solute that will dissolve in a solvent.
