Balancing 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

3
Balancing 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?

4
Balancing Act Concepts600

• How do we balance equations?
• Using the smallest whole number ratio of
  coefficients in front of the formulas

5
Balancing 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

  balance charges of Ionics or Acids

16
Reaction Concepts1000

• What is an Activity Series use for?

27
Bag O Chemical Stuff200

• How are solids, liquids and gases denoted in a
  chemical equation?
• Subscripts (s), (l) and (g)

28
Bag O Chemical Stuff 400

• A solid formed during a chemical reaction is
  called a
• Precipitate

29
Bag 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

30
Bag 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

31
Bag 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
