I dont know much about chemestry, but ive got a program from crocodile clips that simulates chemical reactions, it has a parts bin with beakers and chemicals, powders, and all kinds of stuff. well, i grabed a beaker, and droped in 15g of cobalt chloride powder, and 50mL of Sulfuric acid. it turned red, i think thats what the program uses to tell that whatever it is is hot, so i grabbed a thermometer, switched it to F, and stuck it in the beaker, and reset the mixture, and the temp went from 77F to 220F, and it slowly drops down. anyone know why this happens? or if it even should happen?
