The average atomic mass of Neon would simply be the sum of the weighted average of each isotope. That is:

average atomic mass = 0.905 * 20 + 0.003 * 21 + 0.092 * 22

average atomic mass = 20.187 amu

What is the concentration of H+ ions at a pH = 11?
natta225 [31]

Answer:

\huge 1 × {10}^{-11} \: \: M

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ {H}^{+} ]

Since we are finding the H+ ions we find the antilog of the pH

So we have

11 =  -  log({H}^{+})  \\ {H}^{+} =  {10}^{ - 11}

We have the final answer as

1 × {10}^{-11} \: \: M

Hope this helps you

Salutations!

In which state of matter is there no particle movement

Solid is the state of matter that has no particle movement. Solid is tightly packed, rigid, and does not takes the shape of the container. The only movement that they have is the vibration movement, otherwise, it is still and has no particle movement.

Hope I helped (:

Consider a mixture of oil and water. What terms would you use to describe this mixture? Check all that apply. Heterogeneous homo
GenaCL600 [577]

A mixture of oil and water is:

Heterogeneous

immiscible

<h3>What type of mixture of oil and water is?</h3>

The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water. The mixture can be called as Emulsion. It is an immiscible liquid and the mixture is heterogeneous as oil floats on top of water surface but do not mix with it.

Thus, correct options are Heterogeneous and immiscible.
