Balanced Chemical Equation – Solution
Ba + Na2 → BaNa2
Equation is already balanced.
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
This is an oxidation-reduction (redox) reaction. Na2 is an oxidizing agent, Ba is a reducing agent.
- 2 Na0 + 2 e– → 2 Na-I (reduction)
- Ba0 – 2 e– → BaII (oxidation)
Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.
- Names: Barium.
- Appearance: Yellowish-to-white lustrous solid in various forms.
|Ba + Na2 = Ba2Na|
|Ba + Na2 = Ba2Na2|
|Ba + Na2 = Ba3Na2|
|Ba + Na2 = BaNa|
|Ba + Na2 = Ba2Na10|
