Answer:
protons and neutrons
Explanation:
those particles account for 99.99% of mass
Answer: Cations are positively charged ions.
Explanation: In cations the number of electrons is not equal to the number of positively charged protons. This is due to reason that cations donates their outer valence electrons making the atom less electronegative. The amount of electrons donated indicates the charge of the cation.
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
