A 2.00 g sample of peanut butter is placed into the ignition container of a bomb calorimeter then charged with excess oxygen. The bomb is placed into 2.000 L of water which is equilibrated to 23.750 C. Previously, the calorimeter constant for this bomb calorimeter was determined to be 3.125 kJ/C. After the peanut butter sample was ignited, the water temperature rose to 28.213 C. Required:
Determine the number of Calories in one serving (31.0 g, 2.00 Tablespoons) of peanut butter. Given 1 Calorie is 4184 J.

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
