Examples of chemistry word equations , chemical symbols , state symbols and balanced equations

Example 1

Chemistry word equation:                Aluminium + Hydrochloric acid > Aluminium chloride + Hydrogen

Equation of chemical symbols:         Al  + HCl  >  AlCl3  +  H2

Equation containing state symbols:   Al(s)  +  HCl(aq)  >  AlCl3(s) +  H2(g)

A balanced equation:                      2Al(s)  +  6HCl(aq)  >  2AlCl3(s) +  3H2(g)

Example 2

Chemistry word equation:               Ethane + Oxygen -> Carbon dioxide + Water

  Equation of chemical symbols:      C2H6 + O2  > CO2   +  H2O

Equation containing state symbols:  C2H6 (g) + O2(g)  > CO2(g)   +  H2O(l)

A balanced equation:                      2C2H6 + 7O2  = 4CO2   +  6H2O

State symbols:   (g) = gas   ,   (s) = solid   ,  (l) = liquid   ,  (aq) = aqua

Note: Chemistry software CHEMIX School  uses '>' (greater then) instead of the normal arrow '-->' for separating left and right side of the equation.
