Question

Delore Deginhing this worksheet Predict the products for the following reactions, balance the reactions, and for each reaction indicate the kind of reaction (double displacement, acid/base, Redox or decomposition). For acid base reactions indicate whether the acid or the base is strong or weak) PART 1 1) 3-Na(s) +-1 NaOH(aq) + L-H,so, (aq) a 2S04 (aq)t 2H2011) 2) 2 4) NH, (g)+HO ) 5) --Ca(OH)2 (aq) + AgNO, (aq) (Heat) 6) PBr, (s)- 7) -HBr(aq) +--Fe (s) 8) _ NH, (aq) + HCl (aq) Mg (s) + HCl (aq) 10) -- H2O2 (aq)

Explanation / Answer

1 . 3Na + FeBr3-------------------> 3NaBr + Fe (displacement)

2. 2NaOH + H2SO4----------------> Na2SO4 + 2H2O (acid base reaction) both are strong.

3. 2C8H18(l) + 25O2-----------------------> 16CO2 + 18H2O(oxidation , redox reaction )

4. NH3 + H2O------------------> NH4OH + 2H2 (acid base reaction ) here ammonia is a weak base. it behaves as a lewis base and donates a electron pair but it does not mean H2O is strong acid .here H2O gains the electron pair

5. Ca(OH)2+ 2AgNO3--------------------------> Ca(NO3)2 + 2AgOH (double displacement reaction)

6. PBr5 ---------heat------------> PBr3 + Br2 (decomposition)

7. 2HBr + Fe ---------------------> H2 + FeBr2 (displacement )

8. NH3 + HCl ---------------------> NH4Cl (acid base ) here ammonia is donating a lone pair. NH3 is weak base . HCL is strong acid

9 Mg + 2HCl----------------> MgCl2 + H2(displacement)

10. 2H2O2---------> 2H2O + O2 (decomposition)
