In a constant-pressure calorimeter, 60.0 mL of 0.320 M Ba(OH)2 was added to 60.0 mL of 0.640 M HCl. The reaction caused the temperature of the solution to rise from 21.10 °C to 25.46 °C. If the solution has the same density and specific heat as water, what is Î"H for this reaction (per mole of H2O produced)? Assume that the total volume is the sum of the individual volumes.
Determine the specific heat of a metal object of 19 grams that is heated to 96 degrees Celsius and added to a calorimeter containing 75 grams of H 2 O at 18 degrees Celsius.
Calculate the volume of O2, at STP, required for the complete combustion of 165 g octane (C8H18) to CO2 and H2O.
what is the minimum number of Kilo Joules needed to change 40 grams of water 100 C to steam at the same temperature and pressure?
