∆ m ~ 1.056 The mass defect is the discrepancy between the nucleus of an atom's anticipated mass and its actual mass. This discrepancy is due to the binding energy of a system, which might manifest as excess mass.

Iodine 117 contains 64 neutrons and 53 protons altogether.

because of this, its theoretical mass

Water loses a proton and is acting as an acid is true of water in a base ionization reaction

Water will self-ionize to a very small extent under normal conditions. The reaction in which a water molecule donates one of its protons to a neighbouring water molecule, either in pure water or in an aqueous solution, is called the self-ionization of water.

In an autoionization process, one water molecule can react with another to form an OH– ion and an H3O+ ion:

2H2O(l) ⇆ H3O+(aq) + OH–(aq)

and, In aqueous solutions, H3O+ is the strongest acid and OH− is the strongest base that can exist in equilibrium with H2O.

What is Ionization?

Ionisation is defined as the process by which an atom or molecule gains or loses a positive or negative charge as a result of chemical changes. An ion is an electrically charged atom or molecule that results. If the ion has a negative charge, it is called an anion; if it has a positive charge, it is called a cation.

2.2834 atm of pressure is initially present before the volume of the gas was reduced.

Assuming the condition to be an ideal behavior, the gas sample should satisfy the Boyle's law, which states that

PV = constant when temperature is held constant.

It can be said that, the pressure the gas exerts is inversely related to the volume of the airtight container. Therefore,

P₁V₁ = P₂V₂

On rearranging,

P₁ = (P₂V₂)/V₁

We know that V₁ is 12.35L and V₂ is 5.64L P₂ is 5 atm. On substituting we get,

P₁ = (5x5.64)/12.35

P1₁ = 28.2/12.35

P₁ = 2.2834 atm

Therefore the initial pressure would be 2.2834 atm when the volume of the gas is reduced from 12.34L to 5.64L.

Gaseous air is the sample of matter whose molecules are moving fast, compressible, and can change their shape.

Matter exists in three different states: solid, liquid, and gas. Solids have a distinct volume and shape. Although they have a specific volume, liquids adopt the shape of the container. Gases lack a distinct volume or shape. The particles of gases are fast moving, compressible and can occupy the container in which they are put.

According to the kinetic molecular theory of gases, this state of matter is made up of microscopic particles that are constantly moving apart from one another and squabbling against the container's walls and one another. These collisions are elastic, meaning that there is no overall energy loss as a result of them.

The outerm0st electron shell of an atom is where lone pairs are discovered. With the use of a Lewis structure, they can be located. As a result, when two electrons are coupled but aren't utilized in chemical bonding, they are referred to as lone pairs.

The half-life of a radioisotope is the time it needs for the mass of the radioisotope to halve with respect to its original value.

In this problem, the initial mass of the radioisotope at t=0 is

m0 = 50.0 mg

We see that after t = 1 min, the mass of the isotope is

m(1 min) = 25.0 mg

so, exactly half the initial mass: this means that 1 minute is exactly the half-life of this radioisotope.

So, the amount of mass left after each minute is the following:

m (1 min ) = 25.0 mg (1 half-life)

m (2 min) = 12.5 mg (2 half-lives)

m (3 min) = 6.25 mg (3 half-lives)

To shed energy and become stable, two atoms can come together fundamentally in three different ways. They can give or receive electrons to complete their octet structure.

A link of this kind is created when one atom gains electrons from its outermost level or orbit while the other atom is depleting electrons.
