A chemist has two compounds that do not chemically react. He thinks that by finding the right catalyst, he can get them to react
8090 [49]

Answer:

The chemist is incorrect because a catalyst increases the rate of reaction only.

Explanation:

A catalyst is a substance in the presence of which the speed of the reaction increases. It plays no role in the chemical change taking place.

Thus, if the two compounds are not chemically reacting, a catalyst wont make it happen either.

A chemical reaction occurs when atoms tend to lose or gain electrons. A catalyst has no role to play in this process.

A force of 62 N acts on a 35 kg object for 10.0s. What is the objects change in momentum?
Makovka662 [10]

Answer:

Δp = 620 N.s

Explanation:

  • Newton's second law, was originally conceived  as follows:

       F = \frac{\Delta p}{\Delta t}  (1)

  • In this way, a net force applied on an object, is equal to the rate of change of the momentum of the object regarding time.

       for m= constant, it reduces to F= m*a.

  • Replacing in (1) F= 62 N, and Δt = 10.0 s, we can solve for Δp (object's change in momentum) , as follows:

       \Delta p = F* \Delta t = 62 N* 10.0 s = 620 N*s  (2)
