Combustion reactions are ones that always include elemental oxygen as a reactant. When a hydrocarbon (substance made up of carbon and hydrogen) reacts with oxygen, the products of the combustion reaction are carbon dioxide and water.

Drag and drop the products to the correct reactants for these combustion reactions. The reactants have the correct coefficients for making balanced reactions.

Respuesta :

1. CH4 + 2O2 = CO2 + 2H20                 B.

2. 2CH2H6 + 7O2 = 4CO2 + 6H20      A  

3. C3H8 + 502 = 3CO2 + 4H20            C


How to determine the appropriate products of reaction

To find the appropriate end products, use the following rules

  • The hydrogen ratio should be the same on both the product and reactant sides
  • The oxygen ratio should be the same on both the product and reactant sides
  • The carbon ratio should be the same on both sides.

Thus for equation;

1. CH4 + 2O2 = CO2 + 2H20                 B.

2. 2CH2H6 + 2O2 = 4CO2 + 6H20      A  

3. C2H8 + 502 = 2CO2 + 4H20            C
