Upwelling

Explanation:

The rise of deeper water to the surface is called upwelling.

Upwelling is a term used in oceanography to describe the rise of cold and denser water to the surface.

This occurs usually along the short where wave action is very prevalent.
Surface wave pushes away warm water.
Then deeper nutrient-rich cold water rises due to low density and volume of water on top.
This nutrient rich water supports biological activities because they are rich.
Wind along the coast can also force surface water down.

At a certain temperature the rate of this reaction is first order in SO₃ with a rate constant of 0.208 s⁻¹:

NNADVOKAT [17]

Answer:

0.30 M

Explanation:

Using integrated rate law for first order kinetics as:

$[A_t]=[A_0]e^{-kt}$

Where,

$[A_t]$ is the concentration at time t = ?

$[A_0]$ is the initial concentration = 1.36 M

k is the rate constant = 0.208 s⁻¹

t = 7.30 seconds

So,

$[A_t]=1.36\times e^{-0.208\times 7.30}\ M=0.30\ M$

Write a letter to your friend describing your feelings after you left the school

fredd [130]

Dear friend,
How are you doing? I finally switched to my new school and it's been so hard adjusting. But I know I have a new chance at making new friends and memories. Also, I can learn new things, like interacting with new people and how to keep my anxiety low. I really miss us hanging out and how much we'd laugh and get in trouble at class. But i really hope to see you soon & that it hasn't gone terribly wrong for you since i left.
your friend,
name

What would a 1:1 liquid binary mixture of Cyclohexane and Toluene look like? How would the molecules associate with one another?

Ainat [17]

Answer:

Both compounds are colorless, so a mixture of them will look transparent. Both molecules are nopolar, therefore they will associate with each other through London interactions, also known as Van del Waals forces or as transient dipole-transient dipole interactions.
