carbon dioxide, that is what I found
Answer:
A. To focus on only those ions that form the precipitate
Explanation:
Net ionic equations cancel out the ions that appear on both sides of the reaction because they essentially don't participate in the reaction. This is very useful when dealing with redox reactions because are complicated enough without spectator ions being in the way, so they help focus on those ions that actually form the precipitate.
Key Terms
- Spectator Ions: an ion that does not take part in the chemical reaction.
- Net ionic equations: a equation where ions that appear on both sides are canceled out.
- Redox reaction: an oxidation-reduction reaction.
Answer:
Explanation:
Al2(SO4)3 + 3BaCl2 ====> 2AlCl3 + 3BaSO4
Sorry forgot to say that it is a double replacement. The Ba goes where there Aluminum is and the Aluminum goes where the Barium is.
The internal balance numbers come from the fact that the ions and complex ions have different valance numbers.
