How much energy (in kilojoules) is released when 12.7g of steam at 121.0 degrees Celsius is condensed to give liquid water at 79.0 degrees Celsius? The heat of vaporization of liquid water is 40.67 kJ/mol, and the molar heat capacity is 75.3 J/(K*mol) for the liquid and 33.6 J/(K*mol)for the vapor.
how many ml of concentrated sulfuric acid would be required to mae 1 L of 0.2N solution
Consider a glass of 167 mL of water at 29°C. Calculate the mass of ice at -15°C that must be added to cool the water to 10°C after thermal equilibrium is achieved. To find the mass of water use the density of water = 1.0.
