Transcript

  • 1. Balancing Equations
    By Taylor Reeves & Chris Trotzuk
  • 2. Step One
    NaOH + H2 SO4-> Na2SO4+ H2O
    Have an unbalanced equation.
  • 3. Step Two
    NaOH + H2 SO4-> Na2SO4+ H2O
    It helps to draw boxes around each separate chemical formula so nothing gets mixed up. However, this step is not necessary.
  • 4. Step Three
    NaOH + H2 SO4-> Na2SO4+ H2O
    Next you should make what is called an ‘element inventory’. List all the elements, the number of atoms on the left side of the equation, as well as the number of atoms on the right side.
  • 5. Step Four
    2NaOH + H2 SO4-> Na2SO4+ H2O
    In this example, you start by putting a 2 in front of ‘NaOH’. This changes ‘Na’ to 2, ‘O’ to 6, ‘H’ to 4, and ‘S’ stays at 1.
  • 6. Step Five
    2NaOH + H2 SO4-> Na2SO4+2H2O
    Now to balance the equation, place a 2 in front of ‘H2O’. This makes the right side of the equation the same as the left side.
  • 7. Congratulations!
    2NaOH + H2 SO4-> Na2SO4+2H2O
    Now you have a balanced equation!
