Balanced Chemical Equation – Solution
Cu + 4HNO3 → Cu(NO3)2 + 2NO2 + 2H2O
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
Copper + Nitric Acid = Copper(Ii) Nitrate + Nitrogen Dioxide + Water
This is an oxidation-reduction (redox) reaction. Cu is a reducing agent, HNO3 is an oxidizing agent.
- Cu0 – 2 e– → CuII (oxidation)
- 2 NV + 2 e– → 2 NIV (reduction)
