Answer:
D
Explanation:
My logic: Electricity produces heat, chemical reactions produce heat. And so on.
Answer : The pressure in torr and in atmospheres are, 745 torr and 0.980 atm respectively.
Explanation :
As we are given that the atmospheric pressure is, 745 mmHg.
Now we have to determine the pressure in torr and atm.
Conversions used:
1 atm = 760 mmHg
1 atm = 760 torr
1 mmHg = 1 torr
As, 760 mmHg = 1 atm
So, 745 mmHg =
and,
As, 1 mmHg = 1 torr
So, 745 mmHg = 745 torr
Therefore, the pressure in torr and in atmospheres are, 745 torr and 0.980 atm respectively.
62.3018 g/mol is the molar mass
Answer:
V = 172.28 mL
Explanation:
density is mass divided by volume
p = density
m = mass
V = volume
p = m/v
V = m/p
V = 392.8/2.28
V = 172.28 mL
Answer: the third option, each sub-level electron type has a unique path where it will likely be found.
Explanations:
1) Bhor's model of electrons orbiting the nucleus of the atom was shown to be wrong.
2) The actual model of the atom is the quantum atom model.
3) The quantum atom model depicts the electron in regions called orbitals.
4) The orbitals are the sublevels of energy (or subshells).
These sublevels (orbitals) are identified with the letters s, p, d, and f.
The orbitals s are spherical, the orbitals p are like a dumbbells, d and f orbitals have weirder shapes.
Those orbitasl are kind of electron clouds. The orbitals are defined as regions of the space around the atomic nucleus where the electrons are likely located.
