The study of matter and energy best describes physical science. Hence, option B is correct.
<h3>What is physical science?</h3>
Physical science is the study of the inorganic world.
Physics is a branch of science that studies matter and its motion through space and time, along with related concepts such as energy and force. Physics is one of the "fundamental sciences" because of the other natural sciences (like biology, geology etc.)
Thus the study of matter and energy best describes physical science. Hence, option B is correct.

Answer:
<u>uniform composition.</u>
Explanation:
A phase is a part of a system with uniform composition.
- In physics and chemistry , a phase in a physically distinctive form of matter , such as solid , liquid , gas or plasma.
- A phase matter is characterised by having relatively uniform chemical and physical properities . Phases are different from states of matter.
- The states of matter (e.g ., solid , liquid , gas ) are phases but matter can exist in different phases and yet be in the same type of matter. For example , liquid mixtures can exist in multiple phases such as oily and aqueous phase.
- some different types of phases are : solid, liquid,gas , plasma etc.
- The term phase can also sometime mean describe equilibrium in phase diagram
The ratio of mole number of the reactants and products is equal to the coefficients. So the answer is a. 18.75 mol. b. 35.1 g. c. 1.38 * 10^5 g.
