When a 290-g piece of iron at 180ºc is placed in a 95-g aluminum calorimeter cup containing 250 g of glycerin at 10ºc, the final temperature is observed to be 38ºc. estimate the specific heat of glycerin. use si units, but do not include units in your answer.

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
