Question:-

1. If the surface area of liquid is large then evaporation will be

A. small

B. large

C. moderate

D. slow

Answer:-

B. Large

Explanation:-

Evaporation increases with increasing surface area. This is because the greater the surface area (exposed to the air), the more molecules escape into the air.

More surface area = Higher rate of evaporation.

Then M = mols/L. You know M and mols, solve for L.

Explanation:

3.5/0.1

L= 35

Hope this helps!!

Please tell me if I have made a mistake!!

I enjoy learning from them:)

Answer:

0.32L

Explanation:

Use formula of V= wt/mm•M.
To get this information we need to first get the molar mass (mm).
mm:
K - 2 x 39.09
S - 1 x 32.06
K2S - 110.262 g/mol

Now we plug it back into the equation.
3.5g/ (110.262 g/mol) • (0.100M)
= 0.317 L of solution

To round to the correct number of siginficant figures the answer is.
= 0.32 L

A group of scientists are studying observable matter in a cluster of galaxies. They conclude that the cluster has only a small percentage of the mass required to keep it from
flying apart. Why does the duster remain intact?

Answers

Answer:

it is because of Dark Matter

Dark Matter, component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 30.1 percent of the matter-energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent).

Dark matter is composed of particles that do not absorb, reflect, or emit light, so they cannot be detected by observing electromagnetic radiation. Dark matter is material that cannot be seen directly.

A group of scientists is studying observable matter in a cluster of galaxies. The duster remains intact due to the gravitational pull.

What is a galaxy?

A galaxy is a collection of stars, stellar remains, interstellar gas, dust, and dark matter that are gravitationally bonded together.

Dark matter is a component of the universe whose gravitational pull can be detected rather than its luminosity. The universe's matter-energy ratio is made up of 30.1 percent dark matter, 69.4 percent dark energy, and “regular” visible matter (0.5 percent).

Since dark matter is made up of particles that do not absorb, reflect, or emit light, it is impossible to identify it through electromagnetic radiation observation. Dark matter is a substance that cannot be directly observed.

Therefore, a team of researchers is examining the material that can be seen in a clump of galaxies. Due to the gravitational force, the duster is unharmed.

4. Based on your observations above, which substance needed a greater decrease in kinetic energy in order to change phase?
The substance with
(medium or low) ANSWER: Pick which one it is!
attraction needed more energy transferred out in order to change phase.

Answers

The change in phase of a substance is called a physical change. The substance C with low molecular attraction needs more energy transferred out and thus its kinetic energy have to be decreased to change from gas to liquid.

What is energy transfer?

Energy can neither be created nor be destroyed. However it can be transferred from one form to the other and thus total energy of a system is conserved.

In gaseous state molecules or atoms are far apart and have minimum intermolecular forces of attraction whereas in liquid state they have medium molecular attraction and are a bit close than they are in gas state.

When a substance changes from gas state to liquid state its molecules condenses and becomes more close to each other forming higher molecular attraction.

The gas B have medium molecular attraction and thus will easily liquified with minimum energy transfer whereas, gas C is of less molecular attraction having higher kinetic energy and thus more have to transfer more energy out to liquify.

What is the molarity of a solution of 3.0 mol of KCl in 4.0L of water?

Answers

The number of moles of a solute per liter of solution is measured using the unit of concentration known as molarity.

Thus, The approach for resolving molarity issues is quite straightforward. This describes an easy way to figure out how molarity of a solution.

Remembering the units of molarity (M): moles per liter, is the key to calculating molarity. Calculate how many moles of the solute are dissolved in a solution's liter volume to determine its molarity.

The molarity of a solution made by combining 23.7 grams of KMnO4 with 750 mL's worth of water. You must first determine the amount of moles of the solute because this example lacks the liters or moles required to determine molarity.
