a 75.5 g sample of an unknown solid is heated to 62.2 degrees celcius and placed into a calorimeter containing 96.9g of water at 20 degrees celcius. if the final temperature of the solid sample and water is 31.1 degrees celcius, what is the specific heat of the solid

i just learnt this recently but i need to look through my notes again

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?
