You are conducting a calorimetry experiment using a calorimeter with 500 mL of water in its outer
chamber to determine the enthalpy of reaction of a chemical reaction. The initial temperature of the
water was 25 °C. After the reaction, the temperature of the water was 57.4 °C. Disregarding any heat
loss to the walls of the container, calculate the Hf). (The specific heat of the water is 4.18 J/(g. K).

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
