28) All elements are made of atoms
29)Protons and Neutrons
-Electrons make up the outside of the Nucleus
(80+125+45) / 10 = 250/10 =25
25 meters per minute= 0.41 meters/second
the direction and stopping time is irrelevant to the problem.
Answer:
chemical bond
Explanation:
because atom can join together by forming a chemical bond
Answer is: volume will be 3.97 liters.
Boyle's Law: the pressure volume law - volume of a given amount of gas held varies inversely with the applied pressure when the temperature and mass are constant.
p₁V₁ = p₂V₂.
p₁ = 755 torr.
V₁ = 5.00 l.
p₂ = 1.25 atm · 760 torr/atm.
p₂ = 950 torr.
755 torr · 5 l = 950 torr · V₂.
V₂ = 755 torr · 5 l / 950 torr.
V₂ = 3.97 l.
When pressure goes up, volume goes down.
When volume goes up, pressure goes down.
