Answer:
I think its A. It accepted radiation in a chemical reaction, hope this helped.
Answer:
The answer to your question is Pressure 1 = 1.73 atm
Explanation:
Data
Volume 1 = 5 l
Pressure 1 = ?
Volume 2 = 12 l
Pressure 2 = 0.72 atm
Process
To solve this problem use Boyle's law to solve this problem
Pressure 1 x Volume 1 = Pressure 2 x Volume 2
-Solve for Pressure 1
Pressure 1 = Pressure 2 x Volume 2 / Volume 1
-Substitutiion
Pressure 1 = 0.72 x 12 / 5
-Simplification
Pressure 1 = 8.64/5
-Result
Pressure 1 = 1.73 atm
Answer:
The decay of carbon-14 (14C)
Explanation:
The decay of carbon-14 is used to estimate the age of raw materials, such as paper and parchment
(loc.gov)
The signs of a chemical reaction include
Production of a gas (bubbles)
Production of heat
Production of light
Color change
Production of a solid (precipitate) in a solution
So from those answers we see that A is the correct answer.
