Mass is an intensive physical property because it is dependent on the size of the sample.
anything with plus or minus on them are ions
so that is 4 of them
po4-3
hco3-
al+3
hg2+2
Answer:
Explanation:
HF ,Hydrofluoric acid happens to be a weak acid and as we know that a weak acid is partially dissociated in water.
So when we dissolve HF in water it would subsequently dissociate into H⁺ and F⁻ions . The solution now would contain hydronium ion that is H+ ion.
The solution would also contain dissociated F⁻ ion and solvent H20 molecules.
The following reaction would take place:
HF+H₂O⇆H₃O⁺+F⁻
so the reaction in forward direction is the dissociation of HF into H₃O⁺(that is H⁺) and F⁻ion.
The backward reaction would be the recombination of H₃O⁺(that is H⁺) and F⁻ion to give back HF and H₂O
