(picture)if there is 873.9g of HCl then how much AlCl3 is there​

How can the periodic table be used to predict the behavior of elements?

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.

Name atleast 3 type of energy associated with the microwave
