Balanced Chemical Equation – Solution
2C8H18 + 25O2 → 16CO2 + 18H2O
The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.
Chemical Reaction Information
Octane + Dioxygen = Carbon Dioxide + Water
This is an oxidation-reduction (redox) reaction. C8H18 is a reducing agent, O2 is an oxidizing agent.
- 16 C-9/4 – 100 e– → 16 CIV (oxidation)
- 50 O0 + 100 e– → 50 O-II (reduction)
Reaction Type
Combustion
Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.
