Does anyone know thestructure of petroleum ether?
i've tried chemfinder and it has nostructure.

Petroleum ether is a volatile liquid distilled from petroleum, consisting of a mixture of hydrocarbons.

The structure is attached

Explanation:This petroleum fraction consists of aliphatic hydrocarbons and boils in the range 35-60° C; it is commonly used as a laboratory solvent.

Irrespective of the name, this petroleum fragment is not classified as an ether; the name and term is used only figuratively, showing its extreme lightness and volatility.

(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
