Balancing Chemical Equations:
1) Know the name of each reactant that
is used and each product formed.
2) Find the correct formulas for each
reactant and each product, and use them to write the "unbalanced"
equation.
3) Preserve the law of conservation of
matter by conserving atoms.
Example A:
1) Hydrogen and iodine react to form
hydrogen iodide
2) H2 + I2
--> HI
3) H2 + I2
--> 2 HI (balanced) [Add another HI to conserve
atoms]
Example B:
1) Hydrogen bromide and oxygen react to
form water and bromine
2) HBr + O2
--> H2O + Br2
3) HBr + O2
--> 2 H2O + Br2 [Add another H2O
to conserve O atoms]
4 HBr + O2
--> 2 H2O + Br2 [Add 3 more HBr
to conserve H atoms]
4 HBr + O2
--> 2 H2O + 2 Br2 [Add another
Br2 to conserve Br atoms]
