There seems to be a typo in your question. In the balanced chemical formula for the combustion of propane:
C3H8 + 5 O2 --> 3 CO2 + 4 H2O + energy
the products are on the right side of the arrow: CO2, H2O, and energy
Study island answer: C3H8 + 5O2 3CO2 + 4H2O
heat
C3H8 + O2 ---------> CO2 + H2O UNBALANCED C3H8 + 5O2 ---------> 3CO2 + 4H2O BALANCED
3CO2+8N2+4H2O+heat
it is a chemical change. this is because when you burn anything it is going to be a chemical change
Propane is burned to provide the heat in many cooking grills. The chemical reaction for this process is shown in the equation below. C3H8 + 5O2 ? 3 CO2 + 4H2O + energy What are the products in this chemical reaction? 3CO2 + 4H2O + energy
it would be combustion 3NaHCO3 + C6H8O7 ---> C6H5Na3O7 + 3CO2 + 3H2O When a chemical reaction has CO2 and H2O in it, its then stated as a combustion.
Propane burning reacts with the oxygen in the air. C3H8 + 5O2 → 3CO2 + 4H2O
C3h5(no3)3 → 3co2 + 2.5h2o + 1.5n2 + 0.25o2
C3H8 + 5O2 --> 3CO2 + 4H2OThis is a combustion reaction with propane. Always carbon dioxide and water as products.
Study island answer: C3H8 + 5O2 3CO2 + 4H2O
Nope, combustion
C3H8 + 5O2 -> 3CO2 + 4H2O With combustion reaction such as this always balance oxygen last.
Coefficients :)
heat
reaction: CO2(g) bubbling off during the formation of Trisodium citrate: C6H8O7 + 3NaHCO3 = 3CO2(g) + 3H2O + Na3C6H5O7
C3H8 + O2 ---------> CO2 + H2O UNBALANCED C3H8 + 5O2 ---------> 3CO2 + 4H2O BALANCED
