Dissociation Equations Worksheet
Write balanced chemical equations to represent the slight dissociation or the
complete dissociation for 1 mole of the following compounds. In the case of slight
dissociation use a double arrow and for complete dissociation use a single arrow.
Include phase notation in the equations.
1) silver chloride
2) sodium acetate
3) ammonium sulfate
4) calcium carbonate
5) potassium carbonate
6) sodium hydroxide
7) silver chlorate
8) iron(II) sulfate
9) lead(II) phosphate
10) lead(II) chromate
11) iron(III) chloride
12) calcium nitrate
13) iron(III) oxide
14) copper(II) sulfate
15) mercury(II) sulfide
16) zinc chloride
17) lead(II) acetate
18) aluminum phosphate

Explanation:
Single replacement, one atom takes the place of another. There’s one element and one compound and they switch
element + compound —> (and then either the +ions switch with each other or the -ions)
A+BC—> AC + B
First off, what is nonpoint-source pollution?
It comes from many sources BUT this type of pollution doesn't come from factories discharging their waster, nor sewage pipes, nor smokestack emissions; but rather it comes from rainfall or snow-melt moving through and over the ground. Taking away natural and human-made pollutants.
This being said, the answer, is A. Polluted Rainwater.
