A Review Constants Periodic Table Part A A car with a total mass of 1500 kg (including passengers) is driving down a washboard road with bumps spaced 6.0 m apart. The ride is roughest- that is, the car bounces up and down with the maximum amplitude-when the car is traveling at 6.4 m/s For the steps and strategies involved in solving a similar problem, you may view a Video Tutor Solution What is the spring constant of the car's springs?...

< 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...
