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
  • I wrote the formulas incorrectly and did not
    balance charges of Ionics or Acids

7

11

  • Balance the equation C4H10
    O2 ? CO2 H2O
  • 2C4H10 13O2 ? 8CO2 10H2O

12
Reaction Concepts200
  • What type of reaction follows the pattern AB ?
    A B
  • decomposition

13
Reaction Concepts400
  • What type of reaction follows the pattern AB
    C ? AC B
  • Single replacement

14
Reaction Concepts600
  • Name the types of reactions that follow the
    patterns
    A B ? AB
    AB CD ? AD CB
  • Direct combination (synthesis)
  • Double replacement

15
Reaction Concepts800
  • Combustion reactions always produce two products,
    what are they? What must be present as a
    reactant for a combustion reaction?
  • ?CO2 H2O
  • O2

16
Reaction 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?

17
Reactionary200
  • What type of reaction is MgNH4PO4?Mg2P2O7 NH3
    H2O Double points if you can balance it.
  • Decomposition
  • 2MgNH4PO4?Mg2P2O7 2NH3 H2O

18
Reactionary 400
  • What type of reaction is Na
    H2O ? NaOH H2
  • Double points if you can balance it
  • Single replacement
  • 2Na H2O ? 2NaOH H2

19
Reactionary 600
  • What type of reaction is Fe
    O2 ? Fe2O3 Double points
    if you can balance it and name the product
  • Direct Combination
  • 4Fe 3O2 ? 2Fe2O3 Iron III oxide

20
Reactonary 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
  • What type of reaction is
  • C7H16 O2 ? CO2 H2O
  • Double points if you can balance it
  • Combustion
  • C7H16 11O2 ? 7CO2 8H2O

22
Predicting Ill stay single200
  • Predict the products given the reactants Zn
    CuSO4?
  • ? ZnSO4 Cu

23
Predicting Ill stay single 400
  • Predict the products given Mg
    HCl ?
  • ?MgCl2 H2

24
Predicting Ill stay single 600
  • Predict the products given
  • AgNO3 Cu ?
  • ? CuNO3 Ag

25
Predicting Ill stay single 800
  • Predict the products given Pb(NO3)2 Mg ?
  • ?Mg(NO3)2 Pb

26
Predicting Ill stay single 1000
  • Predict the products and balance the equation
    given
  • Al Fe2O3 ?
  • 2Al Fe2O3 ? Al2O3 2Fe

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

32
Chapter 78200
  • In a circle, what physics concept is thought of
    as linear speed?
  • tangential speed

33
Chapter 78400
  • What is confused with centrifugal force in
    rotational motion?
  • inertia

34
Chapter 78600
  • Work in a circle is called?
  • torque

35
Chapter 78800
  • The constant of Newtons Universal Law of
    Gravitation is?
  • 6.67 x 10-11 Nm2/kg2

36
Chapter 781000
  • Dan has a mass of 83.2 kg and Nate has a mass of
    57.3 kg. What is the gravitational force between
    them if they are sitting .800 m apart?
  • 5.00 x 10-7 N

37
Final Jeopardy
  • State Newtons Third Law
  • For every action, there is an equal and opposite
    reaction.
