Describe what the heating curve of ethanol shows about the rate of temperature increase and the enthalpy of vaporization. A) The temperature increase converts bonding forces into intermolecular forces.

Name three of the most sensitive parts of your body (Appropriate parts. Ex: finger, wrist, shoulder, etc.)

A very simple assumption for the specific heat of a crystalline solid is that each vibrational mode of the solid acts independently and is fully excited and thus cv=3NAkB=24.9 kJ / (kmol⋅K). This is called the law of Dulong and Petit.

How many liters of 0.85 M HCl solution would react completely with 3.5 moles Ca (OH) 2?

The specific heat of aluminum is 0.897 J/g•°C. Which equation would you use to calculate the amount of heat needed to raise the temperature of 0.75 g of aluminum from 7°C to 29°C? A. Q = 0.75 g x 0.897 J/g•°C x 22°C B. Q = 0.75 g x 0.
