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 elements are found in the following chemical equation? K + Cl → KCl A. 1 B. 2 C. 3 D. 0

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.
