The chemical name for MnS₂ is manganese sulfide.
Ionic compounds are formed when ions with opposing negative and positive charges form ionic bonds and form compounds, which are compounds made of ions.
Ionic compounds are named by stating the cation first, followed by the anion. When a neutral atom loses one or more electrons, it acquires a positive charge and is called a cation and when an atom gains one or more electrons, it becomes an anion and acquires a negative charge.

Answer:
Manganese(II) sulfide
Explanation:
is a chemical compound of manganese and sulfur. It occurs in nature as the mineral alabandite (isometric), rambergite (hexagonal), and recently found browneite (isometric, with sphalerite-type structure, extremely rare, known only from a meteorite).
An element's chemical properties are determined by the number ofelectrons .
The number of electrons determine chemical properties of an atom as they are present in equal number outside the nucleus as that of protons .Protons contribute to the mass of an atom and give an identity to an atom .
As protons are positively charged there is a need to balance this positive charge and it is balanced by an equal number of electrons .As the valence electrons are the electrons which take part in chemicalreactions the element's chemical properties are determined by the number of electrons.
The number of neutrons has a negligible effect on the chemical nature of elements as they are neutral and have no charge.Indirectly, it's the electronic configuration of an element which determines the chemical properties of any element.

b)1.00 mol L KOH (aq)
c)1.00 mol L NaCL (aq)
d)1.00 mol L solution of CaCL2 (aq)
At equal concentrations, which of the following solutions is the most conductive?
a) C6H12O6 (aq)
b) CH3COOH (aq)
c) HClO4 (aq)
d) CH3OH (aq)
The solution with the highest pH is KOH, because it's a strong base. The most conductive solution would be HClO4, because it's a strong acid and dissociates into ions which are responsible for conducting electricity.
The solution that has the highest pH is b) 1.00 mol L KOH (aq). In the pH scale, lower values (0-6) represent acids, and higher values (8-14) represent bases. As KOH is a strong base, it dissociates completely in water to form K+ and OH- ions, thereby increasing the pH of the solution.
On the other hand, HNO3 is a strong acid and would have a low pH. NaCL and CaCL2 are salts and make neutral solutions, resulting in a pH of around 7.
The most conductive solution at equal concentrations would be c) HClO4(aq). Ionic compounds are good conductors of electricity in a solution since they dissociate into ions. HClO4 is a strong acid and would conduct electricity better than the others. The conductivity is due to the presence of ions which carry the current.

A 1.00 M solution of KOH (aq) would have the highest pH because it is a strong base. A 1.00 M solution of HClO4 (aq) would be the most conductive as it is a strong, fully ionizing acid that produces a high number of ions.
In terms of pH, a solution of 1.00 M KOH (aq) would have the highest pH. The reason is that KOH is a strong base and it completely dissociates in water to form K+ and OH- ions, the latter of which increase the pH of the solution. HNO3, on the other hand, is a strong acid and would result in a low pH. NaCl and CaCl2 are salts and would result in neutral or slightly acidic or basic solutions, depending on the corresponding acidity or basicity of their constituent ions.
Regarding the conductivity, a 1.00 M solution of HClO4 (aq) would be the most conductive. Conductivity relies on the number of ions present in the solution that are capable of carrying current. HClO4 is a strong, fully ionizing acid producing a high number of ions in the solution. The other solutions either are weak acids like CH3COOH, which ionize only partially, or contain compounds like C6H12O6 and CH3OH that don't ionize at all.

The pH of a 0.020 M aqueous solution of propionic acid is 1.70.
Aqueous solution is defined as a chemical mixture in which water serves as the solvent. Aqueous solutions are made up of water and one or more dissolved materials. Solids, gases, or other liquids can all dissolve in an aqueous solution. A mixture needs to be stable in order to be considered a true solution.
pH is defined as a scale that is used to describe an aqueous solution's acidity or basicity. A high pH in the body can happen for a number of reasons, such as faulty kidney/liver function, digestive issues, drug side effects, and lung issues. When the body's levels of carbon dioxide, an acid, are too low, respiratory alkalosis occurs.
pH = -log[H+]
pH = -log [ aqueous solution ]
pH = - log [ 0.020 ]
pH = 1.70
Thus, the pH of a 0.020 M aqueous solution of propionic acid is 1.70.

Answer:
Explanation:
Assume 100% ionization:
1) 0.100 M solution K₂SO₄
This means, that you have to find which of the choices is a solution that contains the same 0.300 M ion concentration.
2) 0.0800 M Na₂CO₃
This is not equal to 0.300 M, so this solution would not contain the same total concentration as a 0.100 M solution of K₂SO₄, and is not the right answer.
3) 0.100 M NaCl
This is not equal to 0.300 M ion, so not a correct option.
4) 0.0750 M Na₃PO₄
Hence, this ion concentration is equal to the ion concentration of a 0.100 M solution of K₂SO₄, and is the correct choice.
5) 0.0500 M NaOH
Not equal to 0.300 M, so wrong choice.

Answer:
The correct answer is the c = negative one
Explanation:
Hello! Let's solve this!
The electron is a particle that is part of the atom. The atom is also made up of neutrons and protons. Protons have a positive charge and are located in the nucleus. Neutrons have a neutral charge and are also located in the nucleus.
The electron has a negative charge and travels its orbitals around the nucleus.
The correct answer is the c = negative one
