Answer:
Concept: Chemical Analysis
- Start by taking inventory of the elements that you have
- Make a list, one for the right side and another for the left side
- Then add coefficients to the elements to the right or left side to balance out the equation
almost positive that its synthesis

I just learned all this in chemistry too lol
got 100 on the test last week so its good
Answer:
<em>The correct option is a) Precipitate: silver sulfate
</em>
<em>
</em>
<em>Net Ionic: 2Ag+ + SO42 →Ag2SO4</em>
Explanation:
When sodium sulfate reacts with silver nitrate, the following reaction occurs:
2AgNO3 + Na2SO4 → Ag2SO4 + 2NaNO3
The NaNO3 is easily soluble in water. However, silver ions form an insoluble solid with SO4. The Ag+ in this compound will be a cation having a positive charge. The SO4- will be an anion having an negative charge.
The table with solubility rules show that the sulfates of Ag+, Ca+, Sr2+, Ba2+, Hg22+ and Pb2+ are insoluble.
Answer:
Emission of heat or light, or a color change.
