Two molecules of butane combine with 13 molecules of oxygen to yield eight molecules of carbon dioxide and ten molecules of water. The balancing process requires carefully adjusting the numbers of one reactant or product at a time.Know More
Begin by writing the unbalanced equation for butane's combustion, C4H10 plus O2 yields CO2 plus H2O. The left side has four carbon, two oxygen and ten hydrogen atoms, while the right side has just one hydrogen atom along with one carbon and two oxygen.
Start by multiplying the CO2 in the products by four to match the four carbons in butane on the reactant side. Next, multiply the H2O in the products by five, resulting in ten hydrogen atoms in both the reactants and products. At this point, there are 13 oxygen atoms in the products, eight in the carbon dioxide and five in the water. Since the oxygen gas in the reactants is a diatomic molecule, 6.5 units of oxygen gas balances out the 13 oxygen atoms in the products. For clarity, double everything in the reactants and products; 2 C4H10 plus 13 O2 reacts to give 8 CO2 plus 10 H2O.Learn more about Chemical Equations
In words, the equation for combustion, in most cases, is a hydrocarbon plus oxygen equals carbon dioxide plus water plus heat. Other cases involve burning hydrogen and oxygen without carbon and reactions that create carbon monoxide.Full Answer >
