The amount of protons in the atoms' nucleus, of this substance, is 33. Since there are 33 electrons in a neutral atom, arsenic-neutral atoms, which have an equal amount of protons and electrons, are neutral.

When an atom is free of all charges, it is considered to be neutral. Ions are named when an atom has a charge on it. As a result, an atom is said to be neutral if it is in its initial state, which is one in which an electron has neither lost nor gained.

Any other atom may contain the same subatomic species that a neutral atom does. Electrons, protons, and neutrons make up the subatomic species. The distinction is that neutral atom have the same number of positive species as negative species, which cancels out all charges. A neutral atom thus has the same number of protons and electrons as a charged atom.

The compounds listed above's bonds angles are;

CH4 has a 109.5° bond angle.

NH3 has a 107° bond angle.

H2O has a 104.5° bond angle.

According to the Valence Shell Electron Pair Repulsion Theory (VSEPR Theory), as the bond angle lowers as a result of the presence of lone pairs, it causes increased repulsion on the bond pairs and, as a result, causes the bond pairs to get closer.

The less repulsion there is, and vice versa, the higher the binding angle.

As a result, H2O repels NH3 and CH4 more strongly than other substances.

The zinc that is added produce the insoluble ZnCO₃ with Ksp = 1.46x10⁻¹⁰:

1.46x10⁻¹⁰ = [Zn²⁺] [CO₃²⁻]

Let's find the moles of ZnBr₂ added = Moles of Zn²⁺ and moles of K₂CO₃ = Moles of CO₃²⁻ we can find the moles of CO₃²⁻ that remains in solution, as follows:

Moles of ZnB₂ (Molar mass: 225.2g/mol) = Moles Zn²⁺:

6.63g ZnBr₂ × (1mol / 225.2g) = 0.02944 moles of Zn²⁺

Moles of K₂CO₃ = Moles of CO₃²⁻:

0.100L × (0.60mol/L) = 0.060 moles CO₃²⁻

Moles CO₃²⁻ in excess: 0.0600moles CO₃²⁻ - 0.02944moles =

0.03056moles CO₃²⁻ / 0.100L = 0.3056M = [CO₃²⁻]

Substituting in Ksp expression:

1.46x10⁻¹⁰ = [Zn²⁺] [0.3056M]

[Zn²⁺] = 4.78x10⁻¹⁰M

Specific heat capacity of a substance is the amount of heat required to raise the temperature by one degree Celsius of one gram of a substance. Therefore,  12.401KJ of heat is required to condense  22.5 g of CH₃OH.

Enthalpy term is basically used in thermodynamics to show the overall energy that a matter have. Mathematically, Enthalpy is directly proportional to specific heat capacity of a substances.

Mathematically,

q = n ×ΔH

where

q = amount of heat= ?

n = no of moles

number of moles of CH₃OH = 22.5 g ÷32.04 g/mol

number of moles of CH₃OH = 0.70 moles

ΔH = enthalpy =38.0 kJ/mol
