• Proportion stopping distance?

The stopping distance of a car is directly proportional to the square of the speed of the car. If a car traveling 50 miles per hour has a stopping distance of 170 feet, find the stopping distance of a car that is traveling 70 miles per hour

In a constant-pressure calorimeter, 60.0 mL of 0.810 M H2SO4 was added to 60.0 mL of 0.390 M NaOH. The reaction caused the temperature of the solution to rise from 24.09 °C to 26.75 °C. If the solution has the same density and specific heat as water (1.00 g/mL and 4.184 J/g·K, respectively), what is ΔH for this reaction (per mole of H2O produced)?... show more
