Acoffee cup calorimeter with a heat capacity of 6.70 j/∘ c was used to measure the change in enthalpy of a precipitation reaction. a 50.0 ml solution of 0.360 m agno3 was mixed with 50.0 ml of 0.540 m kscn. after mixing, the temperature was observed to increase by 4.06∘c. calculate the enthalpy of reaction, δhrxn, per mole of precipitate formed (agscn). assume the specific heat of the product solution is 4.11 j / (g⋅∘c) and that the density of both the reactant solutions is 1.00 g/ml. calculate the theoretical moles of precipitate formed from agno3 and kscn. moles of precipitate formed from agno3: mol moles of precipitate formed from kscn: mol calculate the heat change experienced by the calorimeter contents, . = j calculate the heat change expierenced by the calorimeter contents, . = j calculate the heat change produced by the solution process, . = j calulate δhsolution for one mole of precipitate formed. δhsolution= kj/mole

Select the correct text in the passage. which sentences describe examples of sustainable living? i live in an old apartment building downtown, but my company is based in an office park on the outskirts of the city. i drive an old car that needs to be replaced. i plan to buy a hybrid for better gas mileage, but for now i am able to carpool with a couple of friends from work. the drive to the office park is about 45 minutes each way, but we do get to work in a modern building. the architects just received a leed certification for the design.
