A sample of gas at a pressure of 0.850 atm has a volume of 675 mL. What will the volume be if the pressure is increased to 1.50 atm?

382mL

Explanation:

Boyle's Law P₁V₁ = P₂V₂

(0.850atm)(675mL) = (1.50atm)(V₂)

573.75 = (1.50atm)(V₂)

V₂ = 573.75/1.50

V₂ = 382.5mL = 382mL

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
