A metal sample weighing 37.6 grams, which has been heated to a temp of 100 degree cin boling water was placed in 48.6g of waterin a calorimeter. The inital temp of the water was 25.2 degree c. At equilibrium the temp of the water and metal was 30.4 degreec -what was the change of temperature in the water? (in degree c)?
Assume that the heat was completely absorbed by the water and no heat was absorbed by the reaction container or the calorimeter or lost to the surroundings. Calculate the Hrxn per mole of SiH4.
What is the Henry's law constant for the gas if the partial pressure of the gas in air is .0088 atm?
A 14.0 g sample of CaCl2 is dissolved in 121 g of water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat lost to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C·..
