Potassium sulfate has a solubility of 15 g/100 g water at 40°C. A solution is prepared by adding 47 g of potassium sulfate to 15
Vera_Pavlovna [14]
The final homogenous solution, after cooling it to 40°C, will contain 47 g of potassium sulfate disolved in 150 g of water, so you can calculate the amount disolved per 100 g of water in this way:

[47 g of solute / 150 g of water] * 100 g of g of water = 31.33 grams of solute in 100 g of water.

So, when you compare with the solutiblity, 15 g of solute / 100 g of water, you realize that the solution has more solute dissolved with means that it is supersaturated.

To make a saturated solution, 15 grams of potassium sulfate would dissolve in 100 g of water.

A student made the lewis dot diagram of a compound shown. What is the error in the Lewis dot diagram?
zloy xaker [14]

Answer:

B. Both electrons of Mg should be transferred to one O.

Explanation:

Metals react by loosing electrons while non metals react by gaining electrons.

Reactions occur as each element strives to attain an octet electron configuration in the outer energy level.

It is easier for magnesium to loose 2 electrons than to gain six because loosing the two requires less energy.

Oxygen on the other hand reacts by gaining the two electrons lost by magnesium since it is easier to gain the two than to loose the six. Gaining the two electrons for oxygen requires less energy than loosing the six.

In summary, magnesium looses two electrons that are transferred to oxygen.

If a body`s efficiency is 75% what does it mean?​
snow_tiger [21]

Answer: It’s producing 75% of it’s potential.

Example: If I were to be playing basketbal, and my body was working at 75%, then there is 25% of energy that I’m not using, making me worse than if I was using 100%.

When a wavelength (increases/decreases) the frequency (increases/decreases) and the energy (increases/decreases)
tangare [24]

Answer:

As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic
