There are two buffer sol. 1) one is prepared from 50 ml of NH4OH sol.(c=0.1 mol/l) and 50ml of NH4Cl sol. (C =0.1mol/l)
2) second one is prepared from a 50 ml of NH4OH sol. (C=0.05 mol/l) and 50 ml of NH4Cl sol. (C=0.05mol/l).
Which solution is more resistant in respect with strong base addition?

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

i think is conclusions.i think so

the objects have the same charge is correct.
