What is the most specific classification of ca(no3)2
atom
compound
molecule
element

Option (b) is the correct answer.

Explanation:

A compound is defined as the substance in which different atoms chemically combine together in a fixed ratio by mass.

For example, is a compound as here both calcium ion and nitrate ion chemically combine together.

A compound can be broken down into its constituent particles.

Whereas an atom is the smallest particle present in a substance. It is indivisible in nature.

A molecule is a substance that contains either same or different atoms which are chemically combined together.

For example, , etc are molecules.

An element is a substance that consists of only same type of atoms.

For example, aluminium element will consists of only aluminium atoms.

Thus, we can conclude that compound is the most specific classification of .

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
