Relative dating is the process of determining whether an object or event is older or younger than other objects or events. Absolute dating is d<span>etermining the age of an event or object in years. From absolute dating, the real age of the object is obtained which is not present for relative dating. Hope this helps.</span>
The oxidation numbers for Nitrogen are respectively -3, +5, +4
Explanation:
The given data is as follows.
Air is at
and 14.6 psia.
= 0.00015 ft, Flow rate, (Q) = 48000 
(a) Formula to calculate hydraulic radius
is as follows.

= 
=
ft
Formula for equivalent diameter is as follows.

=
=
ft
(b) Formula for velocity floe is as follows.
Q = VA
V = 
=
ft/min
= 24000 ft/min
(c) Formula to calculate Reynold's number is as follows.
= 
=
(as
and
= 0.0443 lb/ft. hr)
= 53742.66 hr/min
As 1 hr = 10 min. So, 
= 3224559.6
(d) Formula to calculate pressure drop
is as follows.

Putting the given values into the above formula as follows.

= 
= 6.238 
After a good long amount of research, I found that the scientific answer to this question would be a big ol’ dink
Answer:
The correct option here is the first option
Explanation:
Covalent bond is the bond that involves the sharing of electrons between the participating atoms. The electrons (in the outermost shells of the atoms) that are involved this sharing are called the "shared pair" while those electrons (in the outermost shells of the atoms) that are not involved in this sharing are called the "lone pair". Bonding eventually leads to each of the participating atoms achieving it's octet configuration.
Carbon will bind covalently with fluorine (to form carbon tetrafluoride) with each of the electrons on the outermost shell of the carbon been shared covalently with fluorine atoms (that also requires just one electron to achieve it's octet configuration). Thus, at the end, we would have one carbon atom being covalently linked to four flourine atoms.
