A dichromate ion has 56 valence electrons. Valence electrons are the electrons that are present in an atom which are responsible or allows the formation of a chemical bond. When you draw the lewis structure of a dichromate ions, you will have to calculate the valence electrons by (6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 ) – (-2) = 56.

39g
Explanation:
Details of the solution is shown below. From the information provided regarding the N2 produced, we could calculate the amount of N2 produced and use that to find the mass of sodium azide reacted.
Hello.
The answer is that these properties are brittle, solid at room temperature, and have a high melting point.
Answer: The formic acid is 3.5 times stronger than acetic acid.
Explanation:
The strength of an acid depends on its acid dissociation constant.
For a hypothetical monoprotic acid HA, the dissociation equilibrium is:
More is the value of , greater is the dissociation and stronger is the acid.
Thus formic acid is 3.5 times stronger than acetic acid.
