2Balancing Act Concepts200
- State the Law of Conservation of Matter.
- During a chemical reaction matter is neither
created or destroyed therefore the mass of the
reactants must equal the mass of the products
3Balancing Act Concepts400
- Why do we balance equations?
- So that we have the same number and types of
atoms on either side of the yield sign. If this
is done then the mass of the reactants will equal
the mass of the products and the Law of
Conservation of Matter will have been applied?
4Balancing Act Concepts600
- How do we balance equations?
- Using the smallest whole number ratio of
coefficients in front of the formulas
5Balancing Act Concepts800
- How are formulas balanced?
- Using subscripts to balance the charges of the
ions in Ionic Compounds and the correct number of
Hydrogen's to balance the anion in Acids.
6 Balancing Act Concepts1000
- What could be a possible reason that you cant
get an equation to balance - I wrote the formulas incorrectly and did not
balance charges of Ionics or Acids

15Reaction Concepts800
- Combustion reactions always produce two products,
what are they? What must be present as a
reactant for a combustion reaction? - ?CO2 H2O
- O2
16Reaction Concepts1000
- What is an Activity Series use for?
- To determine if the free element in a single
replacement reaction is strong enough to displace
the bonded elementin other words will a reaction
occur or not?
17Reactionary200

20Reactonary 800
- Name the reaction type H3PO4
Ca(OH)2 ? Ca3(PO4)2 H2O - Double points if you can name the specific
type of reaction - Double replacement
- Neutralization Reaction (Acid Base ? Salt and
Water)
21 Reactionary1000

- ? CuNO3 Ag
25Predicting Ill stay single 800
- Predict the products given Pb(NO3)2 Mg ?
- ?Mg(NO3)2 Pb
26Predicting Ill stay single 1000
- Predict the products and balance the equation
given - Al Fe2O3 ?
- 2Al Fe2O3 ? Al2O3 2Fe
27Bag O Chemical Stuff200
- How are solids, liquids and gases denoted in a
chemical equation? - Subscripts (s), (l) and (g)
28Bag O Chemical Stuff 400
- A solid formed during a chemical reaction is
called a - Precipitate
29Bag O Chemical Stuff 600
- During a combustion reaction is more energy taken
in by the reactants or release as products form? - More energy is release as the product bonds form
that is taken in by the reactants, therefor the
reaction is exothermic and products energy
30Bag O Chemical Stuff 800
- Predict what will happen
- Ag KCl??
- No reaction will occur, Ag is lower on the
Activity Series so it cannot displace K
31Bag O Chemical Stuff 1000
- Predict the products given
- MgBr2 F2 ?
- ?MgF2 Br2 Yes it is a single replacement
reaction, in this case F2 is a much more reactive
element so it can replace Br2
