Which of the following is a polar molecule?

saveliy_v [14]

Hopefully this helps, this is basically simplified but you could ask me for a more detailed explanation. But evaporation works by water on the ground(puddles, lakes, etc) turn into a vapor, which means the water tunrs into gas, which is invisible. Then that water goes up and is stored in the clouds which would then become water and fall into a puddle and the cycle repeats! Hope this Helped!

When designing an experiment, scientists make predictions about what results will occur if their hypothesis is correct. One of t

lesya692 [45]

Answer:

There is no formation of shmoos

Explanation:

If the hypothesis that says "Fus3 kinase is required for the signal transduction pathway leading shmoo formation" is correct, then a strain with a deletion Fus3, is not going to render Fus3 kinase, at least active. By this reason, there will not be shmoo formation

1 If 5.80 L of gas is collected at a pressure of 92.0 kPa, what volume will the same gas occupy at 101.3 kPa if the temperature

Anni [7]

Answer:

The volume that the same gas will occupy at 101.3 kPa if the temperature is kept constant is 5.27 L.

Explanation:

As the volume increases, the particles (atoms or molecules) of the gas take longer to reach the walls of the container and therefore collide with them less times per unit of time. This means that the pressure will be lower because it represents the frequency of collisions of the gas against the walls. In this way pressure and volume are related, determining Boyle's law that says:

"The volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure"

Boyle's law is expressed mathematically as:

P * V = k

Now it is possible to assume that you have a certain volume of gas V1 that is at a pressure P1 at the beginning of the experiment. If you vary the volume of gas to a new value V2, then the pressure will change to P2, and it will be fulfilled:

P1 * V1 = P2 * V2

In this case, you have:

P1= 92 kPa
V1= 5.80 L
P2= 101.3 kPa
V2= ?

Replacing:

92 kPa* 5.80 L= 101.3 kPa* V2

and solving, you get:

$V2=\frac{92 kPa* 5.80 L}{101.3 kPa}$

V2= 5.27 L

<u><em>The volume that the same gas will occupy at 101.3 kPa if the temperature is kept constant is 5.27 L.</em></u>

A chemist adds of a sodium thiosulfate solution to a reaction flask. Calculate the mass in grams of sodium thiosulfate the chemi

schepotkina [342]

This is a incomplete question.The complete question is:

A chemist adds 180.0 ml of a 1.77 mol/L of sodium thiosulfate solution to a reaction flask. Calculate the mass in grams of sodium thiosulfate the chemist has added to the flask. Be sure your answer has the correct number of significant digits.

Answer: 50.4 g

Explanation:

To calculate the number of moles for given molarity, we use the equation:

$\text{Moles of solute}={\text{Molarity of the solution}}\times{\text{Volume of solution (in L)}}$ .....(1)
