Answer:
4 grams
Explanation:
A = A₀e^⁻kt
A₀ = 125.0 grams
k= 0.693/t(1/2) = (0.693/68.8) yrs⁻¹ = 0.01 yrs⁻¹
t = 344.0 years
A = 125.0g·[e^-(0.01yrs⁻¹)(344.0yrs)] = 125(0.032)grams = 4.000g (4 sog. figs. based on A₀ = 125.0 grams)
The closer the orbitals are to the nucleus, the lower they are in energy.
Atomic orbitals are filled with electrons the energy goes from lowest to highest
When multiple orbitals of equal energy have only one electron, the electrons in each must all have the same spin. However, the orbital diagram violates Hunds Rule.
Pauli's exclusion principle states that in an atom or molecule, no two electrons can have the same four quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
Hund's rule of maximum multiplicity states that every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
Under the augmented dry spell over the revive zone condition would a bringing down of the water table in all probability happen.
The most serious result of unreasonable groundwater pumping is that the water table, beneath which the ground is immersed with water, can be brought down. For water to be pulled back starting from the earliest stage, must be pumped from a well that spans underneath the water table.
Answer:
2.5 M NaOH
Explanation:
The solution with the highest molarity is the most concentrated one.
Molarity is the number of moles per unit volume of a solution.
- Molarity =
2.5M implies there are 2 mole of NaOH per solution of this given substance.
This is the highest from the list as other ones falls below it.
The lowest concentration is 0.2M because just 0.2 mole of NaOH is contained per unit volume.
Nonmetal Atom is the answer.
