Transannular strain predominantly responsible for causing cyclooctane to be higher in energy than linear octane.

Linear octane is a chain like structure in which 8 carbon atom are present and cyclooctane is a cycle like structure in which 8 carbon atom are present. cycloalkanes tend to give off a very high and non-favorable energy, and the spatial orientation of the atoms is called the ring strain in that linear octane there is no ring strain because this is like a chain and in cyclooctane transannular strain  is seen because it is cycle like structure the unfavorable interactions of ring substituents on non-adjacent carbons called transannular strain in cyclooctane transannular strain is more that's why  energy is higher than linear octane.

Hydrogen deficiency index (HDI) for a compound with the molecular formula C9H10O.

What is Hydrogen Deficiency Index(HDI)?

A "deficit" of H atoms would exist if any of the bonds were replaced with double or triple bonds or if rings were involved. We may determine whether and how many multiple bonds and rings are present from the molecular formula by computing the index of hydrogen deficit (IHD). IHD is also known as Unsaturation Degree.

The correct option is (e) none of these ,Valency is the ability of an element to combine.

Valency is the ability of an element to combine. Elements in the same group of the periodic table have the same valency. An element's valency is determined by how many electrons make up its outer shell.

A property of an element called "valency" defines how effectively it can meld with other elements. It is a way to count how many electrons are in an atom's outermost shell.

An atom's stability is determined by its valence electrons. Additionally, valence electrons are in charge of an atom's stability. The Octet Rule states that atoms often gain or lose electrons to reach the octet state, which is defined as having eight electrons in their valence shell. They stabilise at this stage.

It is necessary to keep the temperature constant, but not the concentration of the reactants when determining the rate law expression.

What is the rate law expression?

A chemical reaction's rate and the concentrations of the reactants involved are correlated by an expression known as the rate law, commonly referred to as the rate equation or rate law equation.

A frequent way for determining rate laws is the concept of beginning rates. The method includes determining the starting rate of a reaction, as the name initial rate method would imply. To observe how the reaction rate varies, the measurement is repeated for several sets of beginning concentration conditions.

In the first 85.0 s of this reaction, the concentration of no dropped from 1.12 m to 0.520 m .

What is rate of a reaction?

The speed at which a chemical reaction takes place is the rate of the reaction. It is the concentration change per unit time of a reactant in a reaction.

Since the concentration of NO reduces to half its initial concentration in 85 seconds that is from 1.12m to 0.520m, it can be said that 85 seconds is the half life interval for the reaction, Hence on average, half reaction is completed in the time interval of 85 seconds.

A lead ball added to a graduated cylinder containing 30.8 ml of water, causing the level of the water to increase to 89.9 ml, has a volume of 59.1 ml.

Volume is defined as the amount of space that matter occupies. There are three different ways to find the volume:

1) Volume by Space - by measuring its physical dimensions

2) Volume by Density and Mass - by dividing its weight by its density

3) Volume by Displacement - by measuring the volume displaced when immersed in a liquid or gas

To solve for the volume of the lead ball, we can use the displacement method by subtracting the initial volume from the final volume.

If the level of the water increased from 30.8 ml to 89.9 ml upon adding the lead ball, the displaced volume is:

volume = final volume - initial volume

volume = 89.9 - 30.8

volume = 59.1 ml
