100+reactions

You task is described below but in addition, please could you find a you tube video or other suitable video showing the reaction.

Give fully balanced equations for the reactions which occur (if at all) in the following experiments. Use **ionic equations** where appropriate. In each case describe observations such as colour changes, precipitate formation (give the colour), or gas evolution (give the colour or describe as colourless) resulting from the chemical reaction.

Hydrochloric acid (Hydrogen Chloride) + Ammonia Gas

HCl + NH 3 --> NH 4 Cl

MochiiCake~ ;P (Joce:D)

GUESS WHAT?!!!! I'm doing number 2!!! hehehehe.. :P #100reactions 2. Zinc dust is added to a solution of gold III chloride 3Zn(s) + 2AuCl 3 (aq) ---> 3ZnCl 2 (aq) + 2Au (s) ionic equation: 3Zn + 2Au3+ > 3Zn2+ + 2Au Observation: Silver grey metal dissolves into clear solution. the gold solids will be formed.

 WATCH WATCH WATCH XDD

NEXT ONE!!! :D #100reactions 4. Dilute sulphuric acid is added to a copper II nitrate solution H 2 SO 4 (aq) + Cu(NO 3 ) 2 (aq) ---> CuSO 4 (aq) + 2HNO 3 (aq) ionic equation: HELP!! :( Observation: no visible reaction
