Question:

Calculate the molar heat of combustion of anthracene.?

A 2.56 g of anthracene, C14H10, was burned to heat an aluminum calorimeter (mas948 g)The calorimeter contained 1.50 L water with an initial temperature of 20.5 °c and a final temperature of 34.3 °c.Calculate the molar heat of combustion of anthracene.

Answer:

I was disgusted to find out that the veggies at Panda Express are steamed with chicken brothI don't trust ANY soups or rices because chances are they are cooked with chicken or beef stockSome marinara sauces are cooked with italian sausage or procuitto (sp) and italian ham i think I ALWAYS ask and if they look confused make them go ask the chefI sometimes call a restaurant the morning and talk to the chef personally.
You have to be really carefulI'd research everything online before I stepped into another fast food jointSoups can have chicken or fish stock in themYou can sneak in meat in a lot of placesRead labelsAsk questions at restaurantsIf they don't know leave.
They used to get cooked in beef fatNow, most days they'll get cooked in vegetable or cottonseed oilHowever, unless they use a seperate fryer for chips to everything else, there will be cross-contamination from meat or seafood products that also get fryedAs for cheese, vegetarians can eat cheese, it's vegans that don't, but then again, that's up to youBread, bread contains yeast, yeast is a living organism.
Some restaurants do that yesMost chinese food with sauce contains chicken or beef stock, vietnamese uses stock and oyster sauce, thai uses a lot of fish in their sauceEven food that are listed AS vegetarianPizza sauce from chain restaurants and small places often contains stockChicken stock in rice at restaurantsGlycerin, lard, chitin, Carmine - Cochineal.Confectoner's gaze/shellac (its everywhere once you start looking) Also, many cheeses contain Rennet, which is not vegetarian, it is taken from the stomach of a slaughtered calf.
The calculation above has the right process, but the difference in temperature has been calculated incorrectly (it should be 34.3 - 20.5 13.8 degrees C - not 10.8 degrees Celsius)Also my textbook states the specific heat capacity of aluminum is 0.900J/g degCelsius, not .897, but there are always slight variations on that, so just depends on what yours saysOtherwise, it's a great explanation:)
