Gas samples a, b, and c are contained in a system at stp. the partial pressure of sample a is 38.0 kpa and the partial pressure of sample b is 19.0 kpa. what is the partial pressure of sample c?

The total pressure is given by

A system a STP will have a total pressure of 101.325KPa, and so we make P_C the subject of the formula and solve

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.
