Constants| Periodic Table Part A You and your roommate plot to drop water balloons on students entering your dorm. Your window is 30 m above the sidewalk. You plan to place an X on the sidewalk to mark the spot a student must be when you drop the balloon. You note that most students approach the dorm at about 1 m/s. How far from the impact point do you place the X? Express your answer to one significant figure and...

Review Constants Periodic Table Benzoic acid of mass 1.45 g is reacted with oxygon in a constant volume calorimeter to form H20(l) and CO2 (g) at 298 K The mass of the water in the inner bath is 1.70 x 10g The temperature of the calorimeter and its contents rises 2.82 K as a result of this reaction. Part A K Cp.m(H2O,1) - 75.3 J. mol Calculate the calorimeter constant. The standard enthalpy of combustion of benzoic acid at 298...

A Review Constants Periodic Table Part A You are driving your 1400 kg car at 19 m/s down a hill with a 5.0° slope when a deer suddenly jumps out onto the roadway. You slam on your brakes, skidding to a stop. How far do you skid before stopping if the kinetic friction force between your tires and the road is 1.1x104 N ? Solve this problem using conservation of energy. Express your answer with the appropriate units. μΑ 2)...

< 9 of 13 Review Constants Periodic Table Part A A calorimeter contains 28.0 mL of water at 11.0 °C. When 250 g of X (a substance with a molar mass of 60.0 g/mol) is added, it dissolves via the reaction X(s) + H2O(1) X(aq) and the temperature of the solution increases to 30.0 °C. Calculate the enthalpy change, AH, for this reaction per mole of X. Assume that the specific heat of the resulting solution is equal to that...
