The best answer is, “Two clear liquids combine and turn cloudy.”
When water freezes form a liquid to a solid. That’s a physical change.
When water boils, it forms bubbles. That’s a physical change.
When you mix ethanol and water, they form a clear solution. That’s a physical change.
A loss of negatively-charged electrons corresponds to an increase in oxidation number, while a gain of electrons corresponds to a decrease in oxidation number. Therefore, the element or ion that is oxidized undergoes an increase in oxidation number.
Hope this helped
The sum of the heights of all 3 isotopes would be 62+2+8 = 74
<span>The fractional abundance of 20-Ne 2ould be 62/74 = 0.861. </span>
<span>You can just divide the height of each of the other isotopes by the total height to get their relative abundances.
I hope my answer has come to your help. God bless and have a nice day ahead!
