Today s agenda
Today’s Agenda:

  • Catalyst

  • Quiz

  • Notes: Predicting products

  • HW: p. 339 #26


Predicting products
Predicting Products:

  • Combination:

    • Form the ionic compound that results from the two elements

    • Ex: Write the equation for the reaction of solid Be and oxygen gas


Predicting products1
Predicting Products:

  • Decomposition:

    • Separate the elements

    • Ex: Write the equation for the decomposition of HI


Predicting products2
Predicting Products:

  • Single-Replacement:

    • A metal will replace a less active metal in the ionic compound

    • Ex: Write the equation for the reaction of solid iron and aqueous lead (II) nitrate


Predicting products3
Predicting Products:

  • Double-Replacement:

    • Separate the ionic compounds and trade cations to write new ionic compounds

    • Ex: Write the equation for the reaction of NaOH and Fe(NO3)3
