Given that the order of the reaction is zero, one, or two, use the information in the graph to respond to the
following
i. Determine the order of the reaction with respect to ethanol. Justify your answer.
ii. Write the rate law for the reaction.
iii. Determine the rate constant for the reaction, including units.
iv. Calculate the concentration of ethanol in the flask after 2200 seconds.
v. Calculate the pressure, in atm, of ethanol in the flask after 2200 seconds

most likely he is cheating on you

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

(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
