Stoichiometry and Classification of Reactions

For each of the following problems:

1) Predict the states and products (if none are given) using the solubility table and activity series table.

2) Write the oxidation state number (with + or – sign) above each element in each compound. Iron(III) would be +3.

3) Identify the type of reaction.

4) Write a balanced equation.

5) Write a balanced net ionic equation.

6) You have 125.00 g of the 1^st reactant listed. How much of the 2^nd reactant is needed for a complete reaction? How much of each product, in grams, is produced in a complete reaction (100% Yield)?

1^st reactant + 2^nd reactant

a) K₂CO_3(?) + H₃PO_4(aq) ---------------> ?

b) Li_{(s) +} Pb(NO₃)_2(?) -----------------> ?

c) LiOH_(?) + HI_(aq) -----------------> ?

d) Na₂S_(aq) + NiCl_2(?) -----------------> ?

e) CuO_{(s) +} HCl_(aq) -----------------> CuCl_{2 (aq)} + H₂O_(l)

f) Cu_(?) + HNO_{3 (aq)} -----------------> Cu(NO₃)_{2 (aq)} + NO_2(g) + H₂O_(l)
