Which of the following statements is FALSE? H2SO4 + 2 NaOH → Na2SO4 + 2 H2O is a double replacement reaction

2 KClO3 →KCl + 2 O2 is a decomposition reaction.

C6H12 + 9 O2 → 6 H2O + 6 CO2 is a single replacement reaction

CO2 + Na2O → Na2CO3 is a synthesis reaction

ITS FALSE

ExplaC6H12 + 9 O2 → 6 H2O + 6 CO2 is a single replacement reaction

(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
