propane

A. Combustion Ex. C3 H8 + O2  à CO2 + H2O (already has charges because they are covalent and they use diatomic) Ex. C3H8 + O2  à CO2 + H2O 3 C 1 8 H 2 2 O 3 **not balanced** C3H8 + 5O2  à 3CO2 + 4H2O 3 C 3 8 H 8 10 O 10 **balanced**
 * B.  ** A hydrocarbon reacts with oxygen to form CO2 + H2O
 * C.  **  A + O2  à  CO2 + H2O
 * D.  ** The burning of propane C3 H8, results in the production of carbon dioxide and water vapor
 * E.  ** 1st thing you need to do is write all the symbols for all the elements. 2nd thing you need to do is find the charges of each element. 3rd thing you need to do is do the switchero method which is when you switch the charges between elements. 4th thing you need to do is reduce so that your charges are whole numbers.
 * F.  ** The point of balancing an equation is that each side of the equation is equal. 1st thing you do is make sure that you change your sentence into a formula. 2nd thing you do is make a chart that shows all your elements. On the left and right hand side of each of those elements you’re going to write how much of one element is before and after the arrow. If your equation is not balanced you’re going to start plugging in coefficients or numbers before your elements until their balanced.
