Write the correct electrically-neutral chemical formula for these compounds. Mercury(II) sulfite

Iron (III) phosphate

Bromous acid

The answer is c.  h+  and oh−  react to form water (h2o). i just took the test and i got it right. hope this !

#2- the hno3 has a h+ ion and the naoh has an oh- ion

Sink to the bottom. addition of potassium nitrate past it’s dissolution capacity at a particular temperature will cause the extra to just sink to the bottom of the glass.however, if you were to raise the temperature of the solution prior to dissolving it, and then slowly decrease the temperature after the dissolution, you would create a “supersaturated” solution - a solution that has more solute dissolved into it than should be allowed. if you add any extra solute past this, the entire solution would “crystallize,” and this is how you get those cool videos on youtube.
