Explanation:
it is an element
4. The name of the molecular compound, PC15, is a. potassium chloride b. potassium pentachloride c. phosphorus hexachloride d. phosphorus pentachloride
The name of the molecular compound, PCl₅ is d. Phosphorus pentachloride
Further explanationThe naming of chemical compounds is giving a special name to a compound that aims to facilitate the classification of compounds and facilitate the identification of a compound. The rules for naming chemical compounds have been determined by the IUPAC (International Union of Pure and Applied Chemistry)
This nomenclature includes the names of ion compounds, covalent compounds, and polyatomics
For ionic compounds consisting of cations (ions +) and anions (ions -)
The naming is preceded by the cation then the anion with the -ide suffix added
Generally for this ion compound consists of metal elements as cations and non-metals as anions
1. For metal and non-metal compoundsMetal: cation, positively charged.
Nonmetal: negative anion.
The anion cation's charge is crossed
Example:
Fe₂S₃
Fe charge = +3
S charge = -2
The name: metal + non-metal + -ide
Example: BaCl₂ -> Barium chloride
For transition metals, which have several oxidation charges / numbers, write the oxidation number in roman numbers
Example:
SnO: lead (II) oxide
SnO₂: lead (IV) oxide
2. For non-metal and non-metal compoundsThe naming: non-metal + non-metal + suffix -ide name
In the elements given the prefix mono, di, tri, tetra, penta if more than one element is formed
Example:
SO₂: Sulfur dioxide
SO₃: Sulfur trioxide
PCl₅ is a compound with a bond between nonmetals and nonmetals and is included in a nonpolar covalent bond
PCl₅ is formed from the phosphorus element which binds 5 chlorine elements so that the naming follows the rules:
non-metal + non-metal + suffix -ide
so the naming becomes
Phosphorus pentachloride

5. what correct formula of potassium chloride?
I know that Potassium anion is [tex]K^+[/tex] because it is an alkali metal; It belongs to Group 1A. Chloride ion, on the other hand, is [tex]Cl^-[/tex]. Combing these two ions and crossing over the charges, I believe that the chemical formula for Potassium chloride is [tex]KCl[/tex].

6. what is the mass of 4.0×10^23 formula units of potassium chloride?
Answer:
mass KCl = 50 g
Explanation:
Calculating the molar mass of KCl
molar mass = 39.10 g + 35.45 g
molar mass = 74.55 g
Calculating the mass of KCl
mass KCl = 4.0 × 10²³ formula units × (1 mol / 6.022 × 10²³ formula units) × (74.55 g / 1 mol)
mass KCl = 50 g

13. Type of chemical bonds of potassium chloride
Potassium Chloride - Ionic bond
14. Types of chemical bonds of potassium chloride
KCL---------->Ionic Bond
K loses an electron to become K+ (Positive) potassium ion and Cl gains an electron to become Cl-(-negative) Chloride ion. These two then electrostatically bind together to form KCl.
CS2--------------> Covalent Bond. Carbon never forms an ionic bond. Here carbon forms double-covalent bond with the two sulphur atoms.
15. What type of chemical bond is potassium chloride?
Potassium Chloride - Ionic bond

19. How many grams of Potassium hydroxide are needed to neutralize 18.25 g of hydrogen chloride?
Let's make a balance equation for this
Potassium hydroxide = KOH
hydrogen chloride = HCl
HCl + KOH → KCl + H2O
In this equation, the ratio of the number of mole of HCl to the number of mole of KOH is 1:1.
The molar mass of HCl is 36.46.
The molar mass of KOH is 56.11.
Let's start to solve
[tex]18.25g HCl [ \frac{1 mol HCl}{36.46g HCl}][ \frac{1 mol KOH}{1 mol HCl}][ \frac{56.11g KOH}{1 mol KOH}] = 28.09 g KOH[/tex]
Therefore, there are 28.09 g of Potassium hydroxide needed to neutralize 18.25 g of hydrogen chloride.
