Methyl nitrate, CH3NO3，is used as a rocket propellant. The skeleton structure of the molecule is CH3ONO2: The N and three O atoms lie in the same plane, but the CH3 group is not in the same plane as the NO3group. The bond angle C-O-N is 105° and the bond angle O-N-O is 125°, One N-to-O bond length is 120pm and the other two are 136 pm each. a. Draw a Lewis structure of the molecule showing its geometrical shape.

b. Describe the bonding scheme and the probable atomic (including hybrid) orbitals
involved.
c. Explain why all three N-to-O bond lengths are not the same.
d. Is the specie a polar molecule? If so, show the direction of the net dipole.

(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

im doing test rn im going with 2 but ill give answer if itss wrong,   : )
