Analyzing+equations



When you analyze you MUST understand everything.

When drawing the reactants and products you need to understand what the equation tells you and all of its parts. Example:

Ca(OH)2 + 2Na ---> 2 NaOH + 2Ca 1 molecule of calcium hydroxide and 2 atoms of sodium react to produce 2 molecules of sodium hydroxide and 2 atoms calcium

REACTANTS

Calcium hydroxide Ca(OH)2 has 5 atoms ionic 1 molecule Sodium Na 1 atom element 2 atoms

There are 3 molecules because of the coefficients The total number of atoms is 2ca 2o 2 h 2 na =8total atoms

PRODUCTS

Soidium hydroxide NaOH 3 atoms ionic 2 molecules Calcium Ca 1 atoms element 2 atom

There are 4 molecules because of the coeffcients The total number of atoms is 2na 2o 2h 2Ca= 8 total atoms

The total number of atoms of reactants and products should ALWAYS EQUAL because of the law of conservation! Matter is not created or destroyed it is only rearranged!
