SNC 2D Chemistry Unit Test Review
While doing this review please use your periodic table and table of polyatomic ions that
was provided for the first quiz.
Review from the beginning; periodic table and forming compounds.
1. What information can you get about an element by looking at the periodic table?
Use Nickel as your example.
2. What is an ionic compound? A molecular compound?
3. What are the rules for naming each ionic compounds and molecular compounds/
4. What do subscript numbers mean in a chemical formula?
5. What are the five major chemical families on the periodic table? List example
elements for each family
Review from the middle; balancing equations and acids and bases.
1. In a chemical equation what do the large numbers in front of chemical formulas
2. What are the three states of matter and how are they represented in a chemical
3. Please write the balanced chemical equation for the following reaction:
Aqueous sodium chloride reacts with bromine gas to produce solid sodium
bromide and chlorine gas.
4. Balance this equation and write a description of the reaction.
KNO3(s) → KNO2(s) + O2(g)
5. Please create a table listing common characteristics of acids and bases
6. What is used to measure the acidity or basicity of a substance? What are the
strongest acids and bases?
7. What does pH stand for
8. What are the rules for naming acids? Write the formula for nitric acid and the
name of HF.
9. What are the reactants and products of a neutralization reaction?
10. Please write the balanced neutralization reaction that takes place between
sulphuric acid and sodium hydroxide.
11. If the salt (ionic compound) produced from a neutralization is not soluble in water
what will you see?
12. What compounds contribute to acid rain?
13. What is a natural stone that can neutralize acidic lakes?
14. Write the balanced chemical equation for the following neutralization:
hydrochloric acid reacts with aqueous sodium hydroxide to produce aqueous
sodium chloride and water.
15. Balance the following neutralization and write it as a word equation
H2SO4(aq) + KOH(aq) → K2SO4(aq) + H2O
Review from the end: Reaction types
16. What are the five types of chemical reactions and the general formulas to
represent each.
17. Please balance each of the following chemical equations and state what type of
reaction has occurred.
Fe2(SO4)3 + Ba → BaSO4 + Fe
HgO(s) → Hg(l) + O2(g)
Na3PO4(aq) + CuSO4(aq) → Na2SO4(aq) + Cu3(PO4)2(aq)
C3H8 + O2 → CO2 + H2O
Mg(s) + F2(g) → Mg2F(s)
18. What would the balanced chemical equation and word equations be for the
reaction between calcium chloride and sodium carbonate?
Good Luck!!
