Fluorine has C seven valence electrons.
Valence electrons are the electrons that are found on the outer shell of an atom that are capable of participating in chemical reactions. The easiest way to figure out how many valance electrons Fluorine has would be to look it up in a periodic table and notice that it a group 7 element and therefore has 7 valence electrons.
The other way to tell that Fluorine has 7 valence electrons is to notice that an element with an atomic number of 9 has 9 electrons. The electronic configuration of elements has the first 2 electrons go on the first shell or energy level 
, the leaving the next 7 to go to the second shell 
which can take up to 8 electrons.
This means that Fluorine has 7 seven valence electrons.
Answer:
Volume = 75 inch³
Explanation:
Given data:
Area = 12.5 inch
Height = 6 inch
Volume =?
Solution:
Volume = height × length × width
Volume = Area × height
Now we will put the values in formula;
Volume = 12.5 inch² × 6 inch
Volume = 75 inch³
Answer is: branched alkene.
Carbon atoms can be
arranged s<span>traight chain, branched chain and ring.
Hydrocarbon is an organic compound consisting of hydrogen and carbon.
In straight chain carbon atoms are
bonded with only two other carbon atoms in elongate chain.
In branched chain at least one carbon is bonded
with more than two other carbon atoms. In this example </span><span>2-methylpentene</span><span> second carbon atom is bonded with three carbon atoms.
Ring chain hydrocarbons are cyclic hydrocarbons.</span>
Solute s has a distribution constant of 5. 0 between water (phase 1) and hexane (phase 2), then the concentration of solute s in hexane if [s]water is 0. 011 m is 0.055m.
<h3>What is partition Coefficent?
</h3>
It is defined as the ratio of the concentration of solute in two immiscible ( or slightly miscible liquid) in two solids, when they are in equilibrium across the interface between them.
<h3>What is concentration?</h3>
It is defined as the ratio of number of moles of compound to the volume of compound.
Solute S has a partition coefficient of 5 between water and hexane
Partition coefficient Kd = 5.0
Now we calculate the concentration of S in hexane
[hexane]/[water] = Kd
[Hexane]= 5.0 × (water)
[Hexane] = 5 × (0. 011)
[Hexane] = 0.055 m
Thus, we found that the concentration of solute of hexane if water is 0.011m is 0.055m.
