Is matter continuous and therefore has no finer structure or is it discontinuous and thus made or tiny particles

Marta_Voda [28]

Matter is discontinuous, and it is made of tiny particles called atoms

Explanation:

Matter is not a continuous structure, but it consists of tiny particles called atoms.

An atom consists of three types of particles:

Proton: the proton is in the nucleus of the atom. it has a positive electric charge of $+1.6\cdot 10^{-19}C$ (also called fundamental charge). Its mass is $1.67\cdot 10^{-27}kg$ .

Neutron: the neutron is also in the nucleus of the atom, but it has no electric charge. Its mass is similar to the mass of the proton (slightly heavier). Neutrons and protons are held together in the nucleus through the strong nuclear force.

Electron: electrons are found in a "cloud" outside the nucleus. Electron has negative electric charge equal to $-1.6\cdot 10^{-19}C$ . Its mass is much approximately 1800 times smaller than that of the proton, so it is considered as negligible.

For molecules with more than one ionizable groups, such as glycine, which of the following statements is true? For molecules wit

tester [92]

Answer: Option (a) is the correct answer.

Explanation:

The isoelectric point (pI) is actually the pH where a particular amino acid exists as a neutral molecule. This means that if pH equals pI then there will be no electric charge on the molecule.

Therefore, the statement at pH near the pI, nearly all the molecules carry no net charge, is true.

A buffer is composed of a solution of weak acid or base and salt of weak acid/base.So, when pH equals pI then there occurs no net charge. Hence, there will be no existence of conjugate acid-base pair.

Therefore, the statement when the pH is near the pI, the solution is near its maximum buffering ability, is false.

It is known that when pH is less than pI then there will be a net positive charge on the amino acid.

Hence, the statement at a pH near the pI, nearly all the molecules carry a net positive charge, is false.

When pH is greater than pI then amino acid will have a net negative charge. Hence, the statement at a pH near the pI, nearly all the molecules carry a net negative charge, is false.

Thus, we can conclude that out of the given options the statement at pH near the pI, nearly all the molecules carry no net charge, is true.
