Answer: 103.7 kPa
Explanation:
Given that:
initial volume of gas V1 = 445ml
initial pressure of gas P1 = 120 kPa.
new Volume V2 = 515ml
new pressure P2 = ?
Since, only pressure and volume are involved, apply the formula for Boyle's law
P1V1 = P2V2
120 kPa x 445ml = P2 x 515 kPa
53400 = P2 x 515 kPa
P2 = 53400/515
P2 = 103.7 kPa
Thus, the final pressure of the gas is 103.7 kPa
Answer:
It is not a pure substance.
The answer is C because you must do all the other things first to get to the that’s part hope that helps
If two protons are added to carbon, the chemical identity changes to oxygen, which is two spaces over horizontally on the periodic table. The number of protons is what we call the atomic number (Z), and this is what defines the identity of an element. Since we also added two neutrons, this is simply oxygen, or oxygen-16, the most abundant isotope of oxygen.
Force /Area = Pressure
Force = Pressure * Area
