Answer:

The  correct option is  D

Explanation:

From the question we are told that

 The pH of the aqueous solution is  pH  =  7

 The  isoelectric point  is  pl =  9

From the data given we see that the  

        pH is  below  pl

So the protein will have a net positive charge

Which one of the following statements is not true?

Answer:

When magma reaches the surface, its dissolved gas content increases is true

<u>Explanation</u>:

The volcanic eruptions happen because of magma that is expelled on the earth’s surface. At the earth’s depth, all magma have gas dissolved in liquid. When the pressure has decreased the magma rises towards the earth’s surface creating a separate vapour phase.  

As pressure reduces the volume of gas will  expands and giving magma its 'explosive character'. Thus, as magma reaches the surface the dissolved gas content decreases and magma comes out of earth’s surface.

A 250 gram sample of water at the boiling point had 45.0 kj of heat added. how many grams of water were vaporized? heat of vapor
Julli [10]
You have 45 kJ of heat added and for every 40.6 kJ added, one mole is able to be vaporized. Find how many moles you can vaporize.

45 kJ / 40.6 kJ = 1.1 moles

Water is roughly 18 g per mole so 1.1 moles x 18 g per mol = 19.95 grams vaporized

Hope I helped!
