The answer should be 479 i could possibly be wrong but that’s what i got because one mole is 47.90 grams
Protons/Electrons: 92
Neutrons: 140
***REMEMBER: There is always the same amount of protons and electrons. :)
A scientific law is a statement that is universally accepted and answers the "how?" question.
Hope this helps!
Answer:
volume of the gas is 5.0L
Explanation:
Using Boyle's law that state the pressure of a gas is inversely proportional to volume of it occupies when temperature is constant, it is possible to write:
P₁V₁ = P₂V₂
<em>Where P is pressure, V is volume and 1 and 2 are initial and final states.</em>
<em />
If initial volume is 2.5L, initial pressure is 2.0atm and 1.0atm is final pressure, final volume is:
2.0atm*2.5L = 1atm V₂
5.0L = V₂
Thus, <em>volume of the gas is 5.0L</em>.
The answer would be c as the cart is not in motion therefor ruling out kinetic and it is completely at rest making all of it energy potential
