6. 100.0 mL of 1.00 M of HCl and 100.0 mL of 2.00 M of Ca(OH)2 are mixed at 298K. During the experiment, the temperature rose to 298.0067 K. Assume the heat capacities of the two solutions and densities are the same as that of water (4.184 J/g °C and 1.00 g/mL). Calculate the heat of neutralization in units of (kJ/mol H₂0 produced).

Using Charles's Law An arctic weather balloon is filled with 22.7 L of helium gas inside a prep shed. The temperature inside the shed is 9. °C. The balloon is then taken outside, where the temperature is -45. °C. Calculate the new volume of the balloon. You may assume the pressure on the balloon stays constant at exactly 1 atm.
