Write balanced molecular, ionic and net-ionic equations for 10 reactions

(8 precipitate (P) and 2 neautralization)

Use the next few pages to write balanced MOLECULAR, IONIC, and NET-IONIC equations for 10 reactions that occurred during this laboratory experiment. There are more than 10 possible reactions. Choose precipitation reactions and 2 neutralization reactions. Make sure to include the physical states of all the products. Class (circle one): Precipitation or Neutralization Reaction 1.

Answer 1

Precipitation Reactions : chemical reaction occuring in aqueous solutions where two ionic bonds Combine to form some insoluble salls widely known as precipitates and the chemical reaction would be precipitation. 8 examples from the given table: 1.)

(just to make it understand mathematically). Otherwise in terms of chemistry when same entities are at reactant and product side, they will have no effect on over all or Net equation. So, A n) + 3 fon) + 3Nter) + 30H (2) Al(OH)3 (6) + 3rd Cr) + deco) so, our Net ionic Equation would be પિતા - / / . . . . . ) 222)ોનું 3+ DÁShot on Oneplus > Al(OH), con Powered by Dual Camera (precipitate ) ** (ppt)
