You need a density less than water enough strength not to bend or break
Answer:
Measure 20mL of the stock
Explanation:
All we need to do is to find the volume of the stock solution needed. This is illustrated below:
C1 = 2M
V1 =?
C2 = 0.400 M
V2 = 100mL
C1V1 = C2V2
2 x V1 = 0.4 x 100
Divide both side by 2
V1 = ( 0.4 x 100) /2
V1 = 20mL
Therefore, to prepare the solution, we will measure 20mL of the stock solution and make it up to the 100mL mark.
Convection currents are caused by the movement of the magma in the mantle.

Good Luck Studying :)
Diatomic molecules are the molecules that you can find them in natural bonded to itself. example: O₂, N₂ or Br₂.
the answer is hydrogen ---> H₂
I have attached a little trick to remember these.
I heard that most of the time water found in watersheds aren’t usually clean nor safe for drinking, but i know that there are very few that are somewhat safe for drinking. It’s just not usually common to find clean and healthy watersheds though.
