Scientists believes that the universe is made out of gas, hydrogen, and helium.
Some people think that the universe is made up of baryonic matter. Its the same kind of matter that makes up everything on earth and all the stars (protons, electrons and neutrons).

Hope this helped :)
Have a great day

<h3><u>Answer;</u></h3>

pH = 6.34

<h3><u>Explanation;</u></h3>

pH is given as -log{H+]

But;

pH + pOH = 14

However;

pOH = -log [OH-]

[OH-] =  2.20 × 10−8 M

Thus;

pOH = -log (2.20 × 10−8 M)

        = 7.66

But;

pH = 14 - pOH

     = 14 - 7.66

     <u>= 6.34 </u>

When water evaporates
vladimir1956 [14]

c) The motion of water molecules causes them to leave the liquid and become a gas

Explanation:

When water evaporates, the motion of water molecules causes them to leave the liquid and become a gas. Evaporation is merely a phase change in which liquids changes to solid.

  • During the process of evaporation, heat energy causes the motion of the particles or molecules to increase.
  • This will then break the intermolecular forces holding them together leading to more freedom of the molecules.
  • The molecules will then move from being liquids to solids.
