Fluorine belongs to group 17. How many covalent bonds are formed between two fluorine atoms?

2 answers:

7 0

Answer: 1

Fluorine is in group 7, meaning that it has 7 valence shell electrons and to fulfill the octet rule it can only obtain 1 more electron.

When bonding the last lone pair for each of the two fluorine atoms together you create a total of two electrons shared between each.

Therefore you get a total of 8 valence shell electrons.

Remember: when you have 8 valence shell electrons you have obtained an octet

In other words...

8 valence shell electrons = satisfied octet rule

If 4.12 l of a 0.850 m-h3po4 solution is be diluted to a volume of 10.00 l, what is the concentration of the resulting solution?

statuscvo [17]

The process in which the concentration of the solution is lessened by the addition of water is said to be dilution and equation of dilution relates the initial concentration and volume of stock solution with the final concentration and volume of the solution.

Formula is given by:

$C_{1}V_{1}=C_{2}V_{2}$ (1)

where,

$C_{1}$ is the initial concentration

$V_{1}$ is the initial volume

$C_{2}$ is the final concentration

$V_{2}$ is the final volume

Now,

$C_{1}$ = 0.850 M

$V_{1}$ = 4.12 L

$C_{2}$ =?

$V_{2}$ = 10.00 L

Substitute the give values in formula (1),

$0.850 M\times 4.12L=C_{2}\times 10.00 L$

$C_{2} =\frac{0.850 M\times 4.12L}{10.00 L}$

= $0.3502 M$

Thus, the final concentration of the $H_{3}PO_{4}$ solution = $0.3502 M$

If a solution has virtually virtually no hydrogen ions, what type of pH does it have?

GrogVix [38]

Answer:

13: if thats one of the options

Explanation:

B/c for pH to be that high you have to have alot of OH ions and almost non H+. pH won't be 0 or 2 cuz that implies ALOT of H ions. pH wont be 7 cuz that implies we have 1*10^-7 H ions.
