A 283 g silver figure of a polar bear is dropped into the 217 g aluminum cup of a well insulated calorimeter Containing 263 g of liquid water at 23.7°C period the Bears initial temperature is 96.3°C period what is the final temperature of the water, cup, and beer when they reach thermal equilibrium Librium? The specific heat of silver, aluminum, and liquid water are, respect of Lee, 234J/(KJ times K), 910 J/(KJ times K), and 4190J/(kg*K)

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
