The relationship between an hydrogen atom's energy levels, sublevels and atomic orbitals lies in the fact that hydrogen atom has a shell with energy level of 1 and the energy sublevels are similar as there's only one and have the same energy, and lastly, only one atomic orbital exists in a hydrogen atom
Generally, an atoms energy level, sublevels and atomic orbitals are described by the four quantum numbers if it's Valence electrons.Among laws of atomic theory is the fact that no two electrons can have the same value for all four quantum numbers in an atom.Ultimately, the hydrogen atom has only one electron In the energy level 1, sublevels with equal energy as there are no sublevels in the energy level 1 and only the 1s atomic orbital.

what is the change in atomic mass when an atom emits a beta particle
Answer:
A neutron in the nucleus converts to a proton and a beta particle. The nucleus ejects the beta particle and some gamma radiation. The new atom retains the same mass number, but the number of protons increases to 44.

Answer:
For homogeneous:
Filteration, vaporization, and a reverse chemical reaction
Explanation:
1) precipitation/crystallization reactions - if one of the components can form a solid salt when the solution undergoes several factors (concentration change, temperature change, etc); separation can be done either by filtration, centrifugation, or simple decantation.
(2) chromatography - separation can be based on the mobility of the phases (liquid chromatography, gas chromatography, ion-exchange, etc.)
(3) solvent extraction - if the components are both liquid, separation based on their relative solubilities
(4) distillation - separation based on different boiling points.
(5) magnetic separation - if one of the components have magnetic properties.
(6) electrophoresis - separation of organic molecules based on the type of gel used
heterogeneous:
Main methods of separation of heterogeneous mixtures
- Magnetic separation
- Sublimation
- Decantation

list 5 chemical properties of water??
Answer:
In the presence of a strong electron donor (strong reducing agent), water serves as an oxidizing agent. In the presence of a strong electron acceptor (strong oxidizing agent), water serves as a reducing agent. On-water reactions are a group of organic reactions that take place as an emulsion in water and have an unusual reaction rate acceleration compared with (i) the same reaction in an organic solvent, or (ii) the corresponding dry media reaction.Amphoteric nature : Water can act as both acid and base, which means that it is amphoteric in nature.Hydrolysis reaction : Water has a very strong hydrating tendency due to its dielectric constant. It dissolves many ionic compounds. Some covalent and ionic compounds can be hydrolyzed in water.Redox reactions : Electropositive elements reduce water to hydrogen molecule. Thus, water is a great source of hydrogen.when a solution is diluted, what happens to the number of moles of solute in the diluted solution.

What is the molarity of 930 mL of LiCl solution that contains 139.9 g of LiCl?
O A. 3.5 mol/L
O B. 150 mol/L
hipotle and like
O C. 3.3 mol/L
O D. 3.5 x 10-3 mol/L
Answer:
3.5 mol/L
Explanation:
First convert the 139.9g of LiCl into moles of LiCl. Don't do the sig fig rule until the very end.
Second, take 930mL of LiCl and divide it by 1000 to convert it to liters.
Third use the molarity formula which is M=mol/L and divide 0.930L by 3.300773877mol and you will get 3.549219223. This is where the sig fig rule will come into play. 3.5mol/L is a reasonable answer for this problem.

In the chemical formula for ammonia, NH3 , what does the subscript 3 represent?
the number of ammonia molecules that will bond together
the number of nitrogen atoms in each molecule of ammonia
the number of hydrogen atoms in each molecule of ammonia
the number of nitrogen and hydrogen atoms in each molecule of ammonia
To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. The correct option is option C.
What is atom?Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.
In the given molecule NH₃, the subscript 3 that is written on the foot of element represents the number of hydrogen atoms in each molecule of ammonia.
Therefore, the correct option is option C.
