A calorimeter holds 125 g water at 31.0°C. A sample of hot copper is added to the water. The final temperature of the water and copper is 39.0°C. What is the change in enthalpy
associated with the change in the water's temperature? The specific heat capacity of
water is 4.19 J/gºC. Which substance had a positive q value?

Explanation:

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.
