Answer: The atomic number of an element is determined by the number of protons present in an atom.

Explanation:

There are 3 sub-atomic particles in an atom. They are: electrons, protons and neutrons.

Protons: They carry positive charger and are found in nucleus.
Electrons: They carry negative charge and are found around the nucleus.
Neutrons: They dos not carry any charge and are found in nucleus.

Atomic number is defined as the number of protons that are present in a neutral atom. It is represented as Z.

Z = Atomic number = Number of protons

Hence, the atomic number of an element is determined by the number of protons present in an atom.

c) the salt solubility decreases with temperature.

Salts usually dissolve in water at a given temperature. When water cannot dissolve anymore salt at that same temperature, it is known as a saturation point. With most substances the solubility increases with increase in temperature. Same is the case for a salt like potassium nitrate. With increase in temperature the ability of it to dissolve in water increases. And so with decrease in temperature, the solubility decreases.

Cl2 + 2OH− → Cl− + ClO− + H2O

Nataly_w [17]

Cl2(g) -------> Cl-(aq) + ClO-(aq)

2e- + Cl2(g) -------> 2Cl-(aq) [reduction]

4OH-(aq) + Cl2(g) -----------> 2ClO-(aq) + 2H2O(l) + 2e- [oxidation]
______________________________________...
2OH-(aq) + Cl2(g) --------> Cl-(aq) + ClO-(aq) + H2O(l)

If you can answer as many of these as possible that would be great, will give thanks, 5 stars, and brainliest :)

Answer:

The nucleus of the atom as suggested by "nuclear" chemistry.
Radioactive element are generally very large due to both their high number of protons, neutrons, and electrons.
An excessive amount of protons or neutrons.
Periodic table, table O, and table N.
Personal opinion question.
The atomic number.
It represents the number of protons, and can also represent the number of electrons in a neutral atom (an atom with no charge).
Protons ---- element.
Random, self-generated.
Gamma radiation is the only thing on table O that is mass less. Close to being the same is Beta particles which have almost no mass.
Neutrons and Gamma radiation.
Gamma radiation.
Electrons and Beta particles.
To turn one element into the isotope of another. Yes, I believe it is aptly named because you are changing the identity of the element.
The number of protons because they are what define the identity of an element.

Goodluck!

What is a feed back loop?

Agata [3.3K]

Answer:A feedback loop is a process in which the outputs of a system are circled back and used as inputs. In business, this refers to the process of using customer or employee feedback (the outputs of a service or product), to create a better product or workplace
