<u>Answer: </u>The correct answer is Option A.
<u>Explanation:</u>
Fluorine is the 9th element in the periodic table which belongs to group 17 and period 2. It is a non-metal because it requires an electron to gain its stable electronic configuration.
The electronic configuration of this elements is:
This element requires 1 electron to attain stable configuration. It is an insulator and is not lustrous.
This element easily gains an electron and hence, is considered as a highly reactive non-metal.
Hence, the correct answer is Option A.

Answer:
110ml
Explanation:
<em>Using the dilution equation, C1V1 = C2V2</em>
<em>Where C1 is the initial concentration of solution</em>
<em>C2 is final concentration of solution</em>
<em>V1 is intital volume of solution</em>
<em>V2 is final volume of solution.</em>
From the question , C1=6M, C2=0.5M, V1=10ml, V2=?
volume of water added = final volume -initial volume
= 120-10
=110ml
<h2>Hello!</h2>
The answer is:
Since there is not information about the solute but only its mass, we need to assume that we are calculating the molar concentration of a solution or molarity. So, need to use the following formula:
Now, we know that the mass of the solute is equal 3.5 moles and the volume is equal to 1500 mL or 1.5L
Then, substituting into the equation, we have:
Have a nice day!
