A flask contains a mixture of 8 hydrogen molecules and 2 nitrogen molecules. The temperature and pressure conditions are adjusted so that a maximum amount of ammonia NH 3 will form once the activation energy for the reaction has been exceeded. write the balanced chemical equation for this reaction

i have a feeling this is a gay person trolling to make straights look bad.

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

it's c (engineer's do their work with mechanical stuff not on any living being)

(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
