This statement is false. Everything expands when heated
The correct answer is option B. Where are the regions of electron density?
In the quantum mechanical model of the atom the exact location of an electron is unknown. But there is a probability of finding an electron in a given space. So in quantum mechanics instead of an electron we always refer to electron density, which is simply the probability of finding an electron in space.
Answer:
.500
Explanation:
Use the ideal gas law equation: PV = nRT
Plug in the initial values given:
P = 1.2 atm
V = .500 L
n = number of moles
R = Gas Constant 8.314
T = 25.0 C
(1.2)(.5) = n(8.314)(25)
solving for n we get .00289
Now use the same equation with the new values solving for V
(3.6)V = (.00289)(8.314)(75.0)
V = .4999999 ROund to .500
A measure of how much work we can get from each unit of energy. It's also important because we don't want to kill plants.
The answer I’m pretty sure is c) the upper mantle
