At a certain temperature the rate of this reaction is second order in with a rate constant of : suppose a vessel contains at a concentration of . calculate the concentration of in the vessel seconds later. you may assume no other reaction is important

a coal burning power plant

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

because if the tool that you are using is not balanced it there would be false mass.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
