The concentration of a hydrogen ion is 1.0 x 10 to the -7 power then what is the POh

the pOH is 7.

pH = - log [H+] = 7

pH + pOH = 14

precipitation

explanation:

when it goes from cloud to rain/back to earth in the form of rain

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.
