The following balanced equation shows the combustion of propane (c3h8).
c3h8 + 5o2 3co2 + 4h2o
according to this equation, how many oxygen atoms are in the final products?
4
6
10
8

              10 Oxygen Atoms

                        The balance chemical equation is as follow is as follow,

                         C₃H₈  +  5 O₂    →    3 CO₂  +  4 H₂O

According to this equation, three molecules of Propane when reacted with 5 molecules of Oxygen (Combustion reaction) produces 3 molecules of Carbon dioxide and four molecules of Water.

Hence, as one molecule of CO₂ contains two oxygen atoms then 3 CO₂ will contain six oxygen atoms. Also, as one molecule of H₂O contains one atom of oxygen then 4 molecules will contain 4 atoms of oxygen. Therefore,

         6 O atoms (CO₂) + 4  Oatoms (H₂O)  = 10 Oxygen atoms in total

mention the spill to the teacher clean the area and throw the broken pieces away

explanation:

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
