Calculate the final pressure in the cylinder of a car engine if the original volume was 450 mL at a pressure of 0.80 aim, and the final volume is 120 mL. Assume no change in the
number of molecules or ternperature.

3.0 atm

Explanation:

P1V1 = P2V2

(0.80)(450) = P2(120)

P2 = 3.0 atm

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
