8. Jacob mixed two samples together: a colorless gas with no smell and a colorless
liquid that smells like bleach. He analyzed
the results and found two ending
substances. One of the ending substances
was a green gas. This ending substance is
made up of the repeating group of atoms
shown above. Which of the diagrams to the
left shows the repeating groups of atoms
that make up the samples Jacob mixed
together?

i think its 100.

hope this !

(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
