The answer to your question is D!
yes substances Do react by mass
Answer:
One mole of carbon would look like 25/12.01
Explanation:
Firstly, you will divide 25 by 12.01 and get 2.081598
We know 1 mole equals the gram per atomic mass, so one mole of carbon is 12.01 grams. In conclusion, it would look like 25/12.01.
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
