Balanced Chemical Equation – Solution
C2H5OH + 3O2 → 2CO2 + 3H2O
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
Ethanol + Dioxygen = Carbon Dioxide + Water
This is an oxidation-reduction (redox) reaction. C2H5OH is a reducing agent, O2 is an oxidizing agent.
- 2 C-II – 12 e– → 2 CIV (oxidation)
- 6 O0 + 12 e– → 6 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.
