(A) Erosion erosion breaks down and makes rocks or other things simular to rocks break down
The lowest energy peak for Gallium will be associated with one electron. This is because the configuration of Gallium is:
[Ar], 3d¹⁰, 4s², 4p¹
The one unpaired electron in the 4p orbital is at lower energy than the pair in the 4s orbital. Therefore, it will be released easily via the photoelectric effect.
Answer:
J.J. Thomson
Explanation:
According to my book and wiki, Historically, the mass of the electron was determined directly from combining two measurements. The mass-to-charge ratio of the electron was first estimated by Arthur Schuster in 1890 by measuring the deflection of "cathode rays" due to a known magnetic field in a cathode ray tube. It was seven years later that J. J.
Please correct me if I'm wrong.
Let's assume ideal gas behavior for simplicity. We could use the equation below:
PV=nRT
Solve for n or the number of moles.
n = PV/RT = (3×10⁻³ atm)(1 L)/(0.0821 L·atm/mol·K)(250 K)
n = 1.462×10⁻⁴ moles ozone
For every 1 mole of any substance, Avogadro stipulated that there is an equivalent of 6.022×10²³ molecules. Thus,
# of ozone molecules = 1.462×10⁻⁴ mol * 6.022×10²³ molecules/1 mol
<em># of ozone molecules = 8.8×10¹⁹</em>
To find net force, you simply add all of the forces together.
