The distance from the nucleus is close to the electron orbital of the earth
Answer:
Occurs in substances that have at least one non-metal
Explanation:
The overlapping sets which is denoted by the region B is best attributed to connote with the choice "occurs in substance that have at least one non-metal".
To form an ionic bond, a metal and a non-metal must exchange electrons in order to an electrostatic attraction to occur.
In the case of covalent bonds, non-metals shares their valence electrons to form a bond by attaining an octet configuration.
So, we see that a pre-requisite for both bonds to form is a minimum of the presence of a non-metal.

In the vapour phase, sulphur trioxide dissociates according to the follow
Write , expression for this dissociation reaction.
producing a pressure of 10 atm. Calculate the value of Kp
At a particular temperature, 75% of sulphur trioxide is dissociate
1 x 10 - 15 / 4.2 x 10 - 7
Due to order of operations you have to do do the multiplication and division first, from left to right.
So start with 1.0 x 10. This = 10.
Then you have to skip over the subtraction for now. Multiply 15 by 4.2. This equals 63. Then multiply this by 10, so 630.
Then rewrite the equation. It's 10 - 630 - 7. Then just subtract. 10 - 630 = -620.
-620 - 7 = -627. (Two subtracts make an add)
-627 is your answer
