Answer and Explanation:
Isotopes are same in atomic number and different in atomic mass. Isotopes have same number of electron and proton but different number of neutron and due to same proton their atomic numbers are same and due to different number of neutron their atomic mass are different because neutron also take part in atomic mass
On oxidation of aldehydes produces carboxylic acid functional group.
The product of oxidation of aldehydes depends upon whether the reaction occur in acidic medium or alkaline condition.
If oxidation of aldehydes occurs under acidic condition the product is carboxylic acid but if oxidation of aldehydes occurs under alkaline condition then reduce as well as oxidized product obtained which is known as disproportional product.
The oxidation of aldehydes occur through potassium dichromate, potassium permanganate or many more. The oxidation of aldehydes in the presence of base is known as cannizzaro's reaction.

14 protons, a non-metal, a neutral carbon would have 4 valence electrons (don’t add things to do with its mass or charge, as it’s not finite)
Answer:
We need to add 900 mL of water.
Explanation:
To know the amount of water to add first we need to calculate the concentration of KOH when the pH is 12 and when is 11:
When pH = 12 (initial):
When pH = 11 (final):
Now, by using the following equation we can find the volume of the solution to achieve a pH = 11:
Finally, to bring 100 mL of the initial solution to 1000 mL we need to add the following amount of water:
Therefore, we need to add 900 mL of water.
I hope it helps you!
Using the formula Density = Mass / Volume,
Mass = Density x Volume
Mass = 2.75 x 8 = 22g
