Final answer:
The reactants in the combustion of heptane are heptane (C7H16) and oxygen (O2), while the products are carbon dioxide (CO2) and water vapor (H2O).
Step-by-step explanation:
In the given chemical equation for the combustion of heptane: C7H16(l) + 11O2(g) → 7CO2(g) + 8H2O(g), the reactants are heptane (C7H16) and oxygen (O2). Reactants are the substances that undergo a chemical reaction to form products. In this combustion reaction, heptane (a hydrocarbon) reacts with oxygen to produce carbon dioxide and water vapor. The coefficients in front of each molecule represent the stoichiometric ratio or the balanced quantities of reactants and products.Overall, the reactants in this reaction are heptane (C7H16) and oxygen (O2), while the products are carbon dioxide (CO2) and water vapor (H2O).
The reactants in the combustion reaction of heptane can be identified from the chemical equation C₇H₁₆(l) + 11O₂(g) → 7 CO₂(g) + 8H₂O(g). In this equation, the reactants are heptane (C₇H₁₆) in its liquid form and oxygen gas (O₂). During combustion, heptane reacts with oxygen to produce carbon dioxide (CO₂) and water (H₂O), both in their gaseous states. It is important to balance the equation to ensure that the number of atoms of each element is equal on both sides of the equation, which reflects the conservation of mass.
