100% Homognious mixture.... When something is uniform in appearance it means it's THE SAME.... Homo means "Alike" and "different ingrediantes" means MIXTURE.... not puresubstance...
HOPE THIS HELPS
It’s going to be C solids, liquids, and gases
Answer:
Electrons in the outermost energy level
Explanation:
Electrons fill up levels or rings around the nucleus of the atom. The valance electrons are the electrons on the outermost energy ring or level that is the farthest from the nucleus. Also, all electrons repel each other because they have similar charges and are both negative.
Hope this helps! :)
PH = -log([H+])
[H+] = 10^(-pH)
[H+] = 10^(-8.78) = 1.65*10^-9
[H+][OH-] = Kw
Kw = 1.0*10^-14 at 25 degrees celsius.
[OH-] = Kw/[H+] = (1.0*10^-14)/(1.65*10^-9) = 6.06*10^-6
The concentration of OH- ions is 6.1*10^-6 M.
Answer:
i.e belongs to same group because of valence electrons are same
Explanation:
so it has same chemical behaviour. and q has more energy than r ionisation energy decreases from top to bottom
