Another fossil-fuel gas used in cooking appliances is "propane", used commonly
in backyard grills and RV/camping stoves. Propane is a bigger hydrocarbon: 3
carbons single-bonded in a chain, and the remaining bonds are taken by
hydrogen. Its formula is C3H8 and its structure is shown below. KEY POINT: the
products are the same as the combustion of methane, but more is produced.
The graphic below shows that one propane molecule reacts with 5 oxygen
molecules to form
molecules of carbon dioxide.

- Using collision theory, indicate which of the following statements regarding physical nature of the reactants is true: a) physical nature of reactants The physical nature of reactants does not influence the rate of reaction because reactions happen only on the molecular level. Solids, liquids or gases all influence the rate of reaction the same because they are all in the physical state. Solid state reactants react faster if the particle sizes are larger because reactions occur at the boundary surface with direct contact. Gaseous-state reactions are faster than liquid-state or solid-state reactions because collisions between reactants are more frequent.arrow_forwardDescribe a variety of organic compounds present in living organisms, and explain their importance to those organisms by showing the reaction mechanism (e.g., proteins, carbohydrates, fats, nucleic acids)arrow_forwardConsider iron (Fe), hydrogen gas (H2), and ammonia (NH3).Which of them is or are atoms?
