Predicting Products Race: Answers
Predict the products, balance the equation, determine state of matter and determine type of
reaction.
Finish one at a time, come up and get a checkmark and go on to the next equation. The team to
finish all ten first wins.
1. Sodium fluoride solution and
hydrochloric acid solutions are
mixed
2. Silver nitrate solution is mixed
with lithium bromide solution.
AgNO3(aq) + LiBr(aq) AgBr(s) +LiNO3(aq)
NaF(aq) +HCl(aq)NaCl(aq) + HF(l)s

3. Concentrated sodium hydroxide
solution is mixed with
concentrated sulfuric acid.
2NaOH(aq) +H2SO4(aq) Na2SO4(aq) + 2H2O(l)
4. Zinc metal is placed in
hydrochloric acid.
Zn(s) + 2HCl(aq)  H2(g) + ZnCl2(aq)

5. Ethanol (C2H5OH) is burned in
oxygen.
6. Magnesium is dropped in a copper
nitrate solution.
Mg(s) + 2Cu(NO3)(aq) 2Cu(s) + Mg(NO3)2(aq)
C2H5OH(l) + 3O2(g) 2CO2(g) + 3H2O(g)

7. Hydrogen gas is heated at high
temperatures with oxygen gas.
2H2(g) + O2(g)  2H2O(g)
8. Magnesium is burned in nitrogen
gas.
3Mg(s) + N2(g)  Mg3N2(s)

9. Sodium chloride is separated.
2 NaCl(s) 2 Na(s) + Cl2(g)
10. Sodium sulfide solution is mixed
with zinc nitrate.
