A25.0 ml aliquot of 0.05300.0530 m edtaedta was added to a 38.038.0 ml solution containing an unknown concentration of v3 v3 . all of the v3 v3 present in the solution formed a complex with edtaedta , leaving an excess of edtaedta in solution. this solution was back-titrated with a 0.03100.0310 m ga3 ga3 solution until all of the edtaedta reacted, requiring 11.011.0 ml of the ga3 ga3 solution. what was the original concentration of the v3 v3 solution?

the answer is true. hope it .

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
