Question 1
1.

CHOOSE ALL THAT APPLY.
Which ions are soluble when in a solution with carbonate [CO3-2]?

Question 2
2.

Which of the following is the most reactive cation?

Question 3
3.

Which of the following is the least reactive anion?

Question 4
4.

If you want to indicate that a gas forms in a reaction, which symbol do you use?

Question 5
5.

Choose all that apply.
What gas is formed when the solubility table says 'FIZZ'?

Question 6
6.

If you want to indicate that a precipitate forms in a reaction, which symbol do you use?

When writing formulas, pay particular attention to the following:

  • proper capitalization for symbols
  • parentheses around polyatomic ions that have a subscript of 2 or greater
  • subscripts (see instruction guide below)
Question 7
7.

Type the formula for one precipitate that is slightly soluble.

Question 8
8.

What is the color of the precipitate Mg(OH)2?

Question 9
9.

What is the color of the precipitate CuCO3?

Question 10
10.

Would a precipitate (↓) form when the reagent HCl is added to a solution of KOH?
If yes, give the FORMULA and COLOR of the precipitate. If no precipitate forms, write NOR. You are not writing the full equation here, so use scratch paper to write out the equation if that is helpful to you.

Question 11
11.

Which compound would form a precipitate with K2SO4? (Choose all that would work)

Question 12
12.

Would a precipitate (↓) form when the reagent CuSO4 is added to a solution of KOH?
If yes, give the FORMULA and COLOR of the precipitate. If no precipitate forms, write NOR. You are not writing the full equation here, so use scratch paper to write out the equation if that is helpful to you.

Question 13
13.

Would a precipitate (↓) form when the reagent NaOH is added to a solution of KOH?
If yes, give the FORMULA and COLOR of the precipitate. If no precipitate forms, write NOR. You are not writing the full equation here, so use scratch paper to write out the equation if that is helpful to you.

Question 14
14.

Would a precipitate (↓) form when the reagent BaCl2 is added to a solution of MgSO4?
If yes, give the FORMULA and COLOR of the precipitate. If no precipitate forms, write NOR. You are not writing the full equation here, so use scratch paper to write out the equation if that is helpful to you.

Question 15
15.

CHOOSE ALL THAT APPLY.
Which compounds would form a precipitate with CaI2?

Question 16
16.

What determines if a single replacement reaction occurs?

Question 17
17.

Which element would easily replace zinc in a reaction?

Question 18
18.

Will lead replace copper in a single replacement reaction?

Question 19
19.

CHOOSE ALL THAT APPLY.
Which of the following reactions will take place according to what you have learned about single replacement reactions?

Question 20
20.

If you had to confirm the presence of hydroxide ions (OH-), which would be the best ion to use?

Question 21
21.

Identify each equation as one of the 5 types.

  • Na + HCl → NaCl + H2↑
  • 2C15H30 + 45O2 → 30CO2 + 30 H2O
  • 3HNO3 + Al(OH)3 → Al(NO3)3 + 3H2O
  • O2 + 4Ag → 2Ag2O
  • 2H2O → O2 + 2H2
  • 13O2 + 4C2H5 → 10H2O + 8CO2
  • 4K2CrO4 + 2Cr2O3 + 3O2 → 4K2CrO7
  • BeCrO4 + Ca(C2H3O2)2 → CaCrO4 + Be(C2H3O2)2
  • 4H3PO4 → 2P2O5 + 6H2O
  • 2GaF3 + 3Mg → 3MgF2 + 2Ga
  • combustion reaction
  • decomposition reaction
  • double replacement reaction
  • single replacement reaction
  • synthesis reaction
