The addition of 3.15 g of ba(oh)2.8h2o to a solution of 1.52 g of nh4scn in 100 g of water in a calorimeter caused the temperature to fall by 3.1c. assuming the specific heat of the solution and products is 4.20j/gc, calucluate the aproximate amount of the heat absorbed by the reaction, which can be represented by the following euation:
ba(oh)2.8h2o + 2nh4scn ? ba(scn)2 + 2nh3 + 10h2o

An atom of lithium (li) and an atom of chlorine (cl) engage in a chemical reaction. which correctly describes the structure of the resulting chemical compound? hint: consider the class of each element. the chemical compound will have a network structure. the chemical compound will have triple bonds. the chemical compound will have a ball-and-stick structure. the chemical compound will have double bonds.
