Answer:
C
Explanation:
Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.
Explanation:
It is known that molecular formula of potassium dichromate is 
. As potassium has an oxidation state of +1 and an oxygen atom has an oxidation state of -2.
Let the oxidation state of chromium is x. Therefore, calculate the oxidation state of chromium as follows.
= 0 (as the molecule is neutral)
= 0
2 + 2x - 14 = 0
x = +6
Thus, we can conclude that the oxidation state of the chromium in the potassium dichromate molecule is +6.

Answer:
Electron dot structure
Explanation:
This is because electron dot structure is the structure that shows or indicate valence electrons of an atom and dots
is use around the element symbols . The number of dots shows the total number of valence electrons that are present in the atom of the molecules.
