Balancing Chemical Equations
When balancing equations, it is useful to begin with the equation skeleton.
Then select the coefficients for the elements that appear only once on
each side of the equation. Try to balance carbon and hydrogen atoms
last. The complete equation includes the the physical state shown
in parentheses after the chemical formula for each reactant and product.
The "s" stands for "solid", "g" for "gas" , "l" for "liquid" and "aq" for
aqueous (when a compound is dissolved in water). Here are some unbalanced
equations to practice your balancing skills on:
CuS(s) + O2(g) + C(s)
-----> SO2 + Cu(s)
C6H12O6(aq) + O2
----> CO2 + H2O(l)
C8H18(l) + O2 (g) ----> CO2(g) + H2O(l)
