a solution is prepared by dissolving 50 g of calcium chloride in a 250ml volumetric flask which is then filled with distilled water up to the line-mark. Calculate the molar concentration of the solution.
Waiting time in the queue by the driver can be used as a criterion whether toll plazas customer centric or not. Assume there are 3 counter serving customers. Customers who come will get in the shortest line (based on the number of customers / vehicles in the queue). Assume the...
A 5.0 kg block moving east with speed of 6 kg m/s collides head on with another 8.0 kg block moving west with speed of 4 m/s. After the collision the 5.0 kg block was moving west with speed of 5 m/ s while the 8.0 kg block was moving east. a) What is the speed of the 8.0 kg bl...

If the end point in the titration of oxalic acid with NaOH solution is super-passed (too pink), will the molar concentration of NaOH be hiegher or lower than the actual value ? Explain ..
if air bubbles remain in the burette during the titration, what will the effect be on the calculated values of :: a- the concentration of NaOh b- the molarity of H2SO4 ??
