Balanced Chemical Equation – Solution
Mg + 2H2O → Mg(OH)2 + H2
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
Magnesium + Water = Brucite + Tritium
This is an oxidation-reduction (redox) reaction. H2O is an oxidizing agent, Mg is a reducing agent.
- 2 HI + 2 e– → 2 H0 (reduction)
- Mg0 – 2 e– → MgII (oxidation)
Reaction Type
Single Displacement (Substitution)
Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.
