Name the following compound:
Mg(ClO)2
magnesium chlorate
What is the law of conservation of mass?
In a chemical reaction, the mass of the reactants must equal the mass of the products.
True or false: the reactivity series is used to determine whether single displacement and double displacement reactions will occur.
FALSE!
Reactivity series is ONLY used for SINGLE DISPLACEMENT!

Write the chemical equation for the following:
Propane (C3H8) burns with a gas in the air to produce water, carbon dioxide, carbon monoxide, and leftover carbon
C3H8 + O2 --> H2O + CO2 + CO + C
What are the two types of double displacement reactions?
Precipitate reaction, acid base neutralization
Predict the product(s):

No reaction!
What is the difference between and strong acid and a weak acid?
Strong acids fully dissociate all of its hydrogen ions - weak acids only partially dissociate
Name the following compound:
AuPO4

Most ionic compounds dissolve in water, but some are insoluble in water and form a precipitate.
Silver chloride is one such product. Imagine that you wanted to create silver chloride and you have a solution of silver nitrate. Choose another reactant to react with silver nitrate in order to produce a silver chloride precipitate.
Any ionic compound with chlorine! (ex. NaCl, MgCl2, etc..)
(Think of double displacement reactions!)

Copper (II) roofing would suffer from corrosion over time if it weren't for a chemical reaction that it goes through when exposed to oxygen in the air. When exposed to oxygen, it reacts to form a very hard substance that protects the remaining copper underneath from experiencing corrosion.
Name the type of reaction. Predict the product(s).
Synthesis reaction
CuO
Complete the following neutralization reaction, and BALANCE:
HCl + Mg(OH)2 -->
2HCl + Mg(OH)2 --> 2H2O + MgCl2
