My chemistry teacher asked my class to look up reactions on the web and I can't find what site to look it up!

Question

For example I need to figure the rest of these equations out:

Na2CO3(aq) + HCl(aq) --->

Na2SO4(aq) + BaCl2(aq)

NaCl(aq)+ AgNO3(aq)

NH4Cl(aq) + NaOH(aq)

Ag+(aq) + Cl-

Answer 1

1) sodium carbonate + hydrochloric acid.
a carbonate + an acid gives you carbon dioxide, salt and water
Na2CO3 (s) + 2HCl (aq) --> 2NaCl (aq) + CO2 (g) + H2O (l)

2) barium chloride is used to test for presence of sulphate, with the formation of white ppt (barium sulphate)
Hence you are going to get an insoluble salt and a soluble salt
Na2SO4 (aq) + BaCl2 (aq) --> BaSO4 (s) + 2NaCl (aq)

3) Silver nitrate is used to test for the presence of chloride, with the formation of white ppt (silver chloride)
Hence you are going to get a soluble salt and an insoluble salt
NaCl (aq) + AgNO3 (aq) --> AgCl (s) + NaNO3 (aq)

4) All ammonium salts when heated with strong alkali produced a salt, ammonia gas and water
NH4Cl (aq) + NaOH (aq) --> NH3 (g) + NaCl (aq) + H2O (l)

5) This is an ionic equation, meant to describe the precipitation of silver chloride from an aqueous solution containing silver ions and chloride ions.
Ag+ (aq) + Cl- (aq) --> AgCl (s)

Hope this helps. :)

Answer 2

google.com chemical compound reactions,
also yahoo search the same.

I can help but you must learn about the chemicals within your compounds on your own...and I believe they are in your chemistry book...hint, hint...on the chapter that you are studying now!

Answer 3

GO TO GOOGLE!!!!!!





P.S.Choose me as best answer!!!! :)
