a metal object with a mass of 19g is heated to 96 degrees C, then transferred to a calorimeter containing 75 g of water at 18 degrees C. The water and metal object reach a final temperature of 22 degree C.
a). What is the specific heat of this metal objectb). What is the metal?
what is the vapor pressure(in mm Hg)of a solution made by dissolving 18.3g of NaCl in 500.0g of H2O at 70 degree celcius. The vapor pressure of pure water at 70 degree celcius is 233.7 mm Hg.
Determine the partial pressure and total pressure of the gases and Find the partial pressure of carbon dioxide in a gas mixture
how do you find the specific heat of platinum if 23.6 grams is heated from 10.0c to 20.0c using 30.68 J of heat.
Compute the final temperature of the mixture (assuming no heat loss to the surroundings). The heat capacities of H2O(s) and H2O (l) are 2.08 and 4.18 J/g · °C, respectively, enthalpy of fusion for ice = 6.02 kJ/mol.
