4) A 15.og piece of cadmium metal absorbs 134J of heat while rising from 24.0°C to 62.7° C. Calculate the specific heat of cadmium.​

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

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.

12 is it do you think so
