Oxidation number is charge of element in compound. Can be neutral, positive or negative.
Oxygen in dichromate has oxidation number -2, becauce there are seven oxygens, net oxidation number of oxygen is -14.
2·x(oxidation number of Cr) + 7· (-2) = -2 2x= +12
x= +6, oxidation number of one chromium is +6.
Particles in a gas are far apart compared to a solid or liquid, allowing it not to have a definitive shape or volume. This also means that gases can fill any container and be easily compressed.
Answer:
Explanation:
The strong bases have following properties:
1. In solution, strong bases ionize fully.
2. On dissolving the strong bases in water they produce all hydroxide ion which they have.
3. For strong bases the value of equilibrium constant (Kb ) is large.
4. In general the strong base ionizes completely means concentration of ions are greater means conductivity also greater.
5. For strong bases the value of equilibrium constant (Kb) is large, thus the value of dG0 is very large negative number.
