(9 of anything) plus (8 of the same thing) = 17 of them
In an aqueous solution, the concentration of H3O+ is the same as the concentration of H+. If you know the pH of the solution, then that's equal to 10^(-pH).
A dozen is equal to 12, so 2/3 of a dozen is the same as 12x2/3 = 8
When you flame test the two solutions, any Na solution burns yellow, while any K solution burns violet/purple. So both the KCl and the KBr will burn purple, while both NaBr and NaCl will burn yellow.
If you start out with a solution and you put the same amount of solution in different types of glassware, it will always be the same no matter what.
Homogeneous. The prefix homo means "the same". A solution is the same throughout.
isotonic or isoosmotic
Yes, a solution is a solution by the reflexive property, that states that for all x, x = x
Yes. I assume you mean (x2 + y2) / (a2 + b2) = 1. Set all the variables to the same value - for example, all equal to one - and you have a valid solution.
They are not the same at all! :-P
Yes, the solution is called the Lugol's Iodine Solution. It tests for the polysaccharide of starch.
