Joe student reacts aqueous solutions of Na, co, and Ca(NO3)2. Calcium carbonate and sodium nitrate are produced. He wishes to collect the precipitate from this reaction.
If Joe starts with 10.6 g of Na, co, what mass of CaCO3, should he expect to collect?
+ Ca(NO3)2taq) → NaNO3(aq) + CaCO3(0)
Na, CO3(aq)

(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
