room temperature (22.0 °C), the temperature increased to 29.1 °C. The resultant salt solution had a mass of 18.00 g and a specific heat capacity of 3.74 J K-1 g-1. What is the heat capacity of the calorimeter (in J/°C)?
Note: The molar enthalpy of neutralization per mole of HCl is -55.84 kJ mol-1.
itially, the balloon contains 4 ft3 of hydrogen and it takes 14 seconds to com-
pletely fill the balloon.
(a) At what rate is the balloon filled?
(b) Find a linear function V that models the volume of hydrogen in the balloon at
any time t.
(c) What can you say about the graph of V ? (You do not need to sketch the graph.)
