Because Celcius is a larger amount than Fahrenheit. The units are farther apart.
In living things, the source of the carbon-14 that is used in radiocarbon dating is carbon dioxide in the atmosphere.
Living things inhale oxygen, and exhale carbon dioxide into the atmosphere, which is why the air and atmosphere are so full of it.
Answer
Using the law of reflection—the angle of reflection equals the angle of incidence—we can see that the image and object are the same distance from the mirror. This is a virtual image, since it cannot be projected—the rays only appear to originate from a common point behind the mirror.

D:
When electrons are gained, the charge of the atom decreases.
When you are given an atom with a charge, the oxidation of that atom is the charge. So by going from a Cr^3+ (Oxidation Number = 3) to a Cr^2+ (Oxidation Number = 2), the Oxidation Number thus decreases.
<span>Since the oil slick consists of a single layer, then the thickness of the oil slick is 0.488 nm. When we multiply the thickness of the oil slick by the area A, then we should get the volume of the oil slick 0.708 m^3.
We can set up an equation to find the area A.
(A)(0.488 nm) = 0.708 m^3
A = 0.708 m^3 / 0.488 nm
A = 0.708 m^3 / 0.488 X 10^{-9} m
A = (0.708 / 0.488) X 10^9 m^2
A = 1.45 X 10^9 m^2
The area of the oil slick is 1.45 X 10^9 m^2</span>
