Why must chemical equations be balanced? They must obey the Law of Conservation of Mass that states that matter cannot be created or destroyed, it is conserved.
Atoms are never lost or gained in chemical reactions, they are rearranged. The mass of the reactants must equal the mass of the products. A chemical reaction represents a change in the distribution of atoms, but not in the number of atoms. If the numbers of each type of atom are different on the two sides of a chemical equation, then the equation is unbalanced, and it cannot correctly describe what happens during the reaction.
The last step is to determine the coefficient of the oxygen gas on the LHS. The final balanced chemical equation is. This is a perfect example of a combustion reaction because we have a carbon based compound reaction with oxygen gas to produce carbon dioxide and water.
Noah G. Mar 7, What is the balanced equation for C3H8? What is produced during the combustion of propane C3H8? What is the combustion of propane? What is the balanced equation for propane? What type of reaction is C3H8 5O2? What is the product of CO2 and H2O? What type of reaction is CO2 H2O? What happens when CO2 is mixed with H2O? Is H2CO3 acidic or basic? Is co2 acidic or basic? Which is the strongest acid? Is Na2CO3 an acid or base? Is Na2SO4 acid or base? The coefficient 2 in front of the H2O l makes this clear.
The balance of oxygen and carbondioxide is maintained in the atmosphere by the oxygen released by plants during photosynthesis and carbondioxide released by human,animals etc.
The balance of oxygen and carbondioxide is made due to respreration and photosinthesis. It allows plants, bacteria, and algae to take carbon dioxide and, with the help of a little sunlight, turn it into the oxygen we all breathe.
But now scientists have taken photosynthesis out of the equation and have managed to make oxygen O2 by zapping carbon dioxide CO2 with a laser.
