Answer:
The acronym is used to remember evidence of a chemical change.
Explanation:
P=precipitate
U=unexpected color change
F=fizzing
A=aroma
R=replaced by a new substance
T= temperature change
The answer would be soluble. Think of it like salt. On it's own it is the white substance that you can see, but when you put it in water and stir it disappears. It is still there, but the physical appearance has changed. Also being explosive, flammable, and reactive are all chemical properties. Hope this helped!
<h2>Answer </h2>
Some mass changes into energy
<u>Explanation </u>
Some mass changes into energy are true about both nuclear fusion and nuclear fission. These both reactions produce large amounts of energy. Nuclear fusion is the process in which two light nuclei combine to form a larger nucleus. On the other hand, nuclear fission is reverse in which a heavy nucleus breaks into two light nuclei. Nuclear decay and transmission are also types of nuclear reactions. The matter is not destroyed in nuclear reactions.
Answer:
All liquids are fluids but not all fluids are liquids. Fluids basically describe anything that can flow as a result of a difference in pressure between two points. Liquids on the other hand are a subset of fluids. Liquids are the incompressible fluids. These are the fluids who's density does not change sharply with pressure.
Gases are also fluids, they form the compressible fluids. They do flow as a result of difference in pressure between two points but at the same time they can be compressed or expanded. Their density fluctuates with pressure.
Hence fluids consist of 2 mutually exclusive groups of compressible and incompressible fluids. Liquids are the incompressible fluids and hence form a subset of the more general term fluid.
Rubbing Alcohols are chemical compounds because rubbing alcohol itself is a strecture made up of many different chemicals combinding in a compound that make, C3H8O
