The values of z , n ,a for a pair of atoms can often be compared as follows: Atomic mass, the principal quantum number (n), and the atomic number (z) (a).

The values of z, n, and a are crucial quantities that characterise an atom's characteristics. The number of protons in the nucleus, or the atomic number (z), specifies the element to which the atom belongs. The energy level and spatial distribution of electrons are determined by the principal quantum number (n), with larger values signifying greater distance from the nucleus and higher energy. The total number of protons and neutrons in the atom's nucleus, or atomic mass (a), defines the atom's overall mass. Comparing and contrasting various atoms, such as those that belong to various elements, isotopes, or ionisation states, is possible using the values of z, n, and a.

Shielding is a term used to describe the ability of inner electrons to shield or reduce the effective nuclear charge (Zeff) experienced by the valence electrons in an atom.

The number of valence electrons and the outermost energy level (also known as the primary quantum number or n value) are the same for all elements in a periodic table group (or column). This indicates that the valence electrons in all of the group's atoms have comparable energy levels and shielding effects from the inner electrons. As a result, the number of energy levels, or the primary quantum number (n), and the shielding effect of the inner electrons dictate the trend in atomic radius within a group.

Plate tectonic processes are responsible for various crustal features, such as mountains at convergent boundaries, mid-ocean ridges at divergent boundaries, earthquakes and volcanic activity at transform boundaries, and visible features like rift valleys and subduction zones.

The three types of plate boundaries are convergent, divergent, and transform boundaries.

Many crustal features can be seen as having resulted from plate tectonics. Where two plates come together at a convergent boundary, they collide and form such features as mountains. When two plates move away from each other the result is a divergent boundary, and they form such features as mid-ocean ridges. A transform boundary forms when two plates slide past each other. If the pressure between two plates builds high enough, the plates may move rapidly causing earthquakes and the occurrence of volcanic activity. Features such as ridges and trenches can be seen from space and lend support to the plate tectonics theory.

Molar mass is the mass of one mole of a substance. The molar mass of CO, which stands for carbon monoxide, is 28.01 g/mol.

Molar mass is the mass of one mole of a substance, which is the amount of the substance that contains the same number of particles (atoms, molecules, ions, or formula units) as there are in 12 grams of pure carbon-12. The molar mass of a substance is expressed in grams per mole (g/mol).

In the case of CO, it is a molecule consisting of one carbon atom and one oxygen atom. The atomic mass of carbon is 12.01 g/mol and the atomic mass of oxygen is 16.00 g/mol, as determined by the average weight of their naturally occurring isotopes. So, to calculate the molar mass of CO, we simply add the atomic masses of one carbon atom and one oxygen atom:

Molar mass of CO = (1 x atomic mass of carbon) + (1 x atomic mass of oxygen)

= (1 x 12.01 g/mol) + (1 x 16.00 g/mol)

= 28.01 g/mol

Therefore, the molar mass of CO is 28.01 g/mol. This means that one mole of CO has a mass of 28.01 grams, and that the molar mass of CO can be used in various calculations involving the substance, such as determining the number of moles or the mass of a given amount of CO.

The acid associated with each conjugate base is: conjugate acid of SO₄²⁻ is H₂SO₄⁻, conjugate acid of I- is HI , conjugate acid of OH⁻ is H₂O, conjugate acid of F⁻ is HF, and the conjugate acid of Cl⁻ is HCl (hydrochloric acid).

A conjugate base are those species which remains after an acid has donated a proton (H⁺ ion). In other words, a conjugate base is formed when an acid loses a proton. For example, in the reaction:

HCl + H₂O → H₃O⁺ + Cl⁻

HCl is an acid that donates a proton to water to form the hydronium ion (H₃O⁺). The chloride ion (Cl⁻) is the species that remains after HCl loses its proton and is therefore the conjugate base of the acid HCl. Similarly, water is the conjugate base of the hydronium ion in this reaction.

The conjugate base of H₂SO₄ is SO₄²⁻, which can accept a proton to reform H₂SO₄. Therefore, the associated acid is H₂SO₄.

The conjugate base of HI is I⁻, which can accept a proton to reform HI. Therefore, the associated acid is HI.

The conjugate base of H₂O is OH⁻, which can accept a proton to reform H₂O. Therefore, the associated acid is H₂O.

The conjugate base of HF is F⁻, which can accept a proton to reform HF. Therefore, the associated acid is HF.

Polar molecules are hydrophilic and dissolve in water, while hydrophobic molecules are non-polar and repel water.

Polar particles are hydrophilic, meaning they have serious areas of strength for a for water and will generally break up in it. This is on the grounds that polar particles have a net dipole second, where the circulation of electric charge is unevenly disseminated, bringing about incomplete positive and negative charges. At the point when put in water, the polar particles fall in line with the polar water atoms, shaping hydrogen bonds and dissolving. Interestingly, hydrophobic particles are non-polar and don't have areas of strength for a for water. This is on the grounds that they miss the mark on net dipole second and don't frame hydrogen bonds with water.

Amino acids combine to form proteins through a process called protein synthesis, which involves two main steps: transcription and translation.

• Transcription: In the first step, the DNA sequence that codes for a particular protein is transcribed into a messenger RNA (mRNA) molecule. The mRNA carries the genetic information from the DNA in the nucleus of the cell to the ribosomes, which are located in the cytoplasm.

• Translation: In the second step, the mRNA sequence is read by the ribosomes and translated into a specific sequence of amino acids, which are linked together to form a protein. During translation, transfer RNA (tRNA) molecules bring the appropriate amino acids to the ribosome, where they are added to the growing protein chain in a specific order dictated by the mRNA sequence.

The sequence of amino acids in a protein is determined by the sequence of nucleotides in the DNA that codes for that protein. The specific sequence of amino acids in a protein determines its three-dimensional structure and its function in the body. Proteins are essential for many biological processes, including cell signaling, enzymatic reactions, and structural support.

Answer:

2580 years

Explanation:

Since isotope Z has a half-life of 645 years, that means after 645 years, half of the original amount of isotope Z will decay. So, if 1/16 of the original amount is present, that means there have been 4 half-lives (since 2^4 = 16).

Each half-life is 645 years, so 4 half-lives is 4 x 645 = 2580 years.

Therefore, the age of the sample is 2580 years.
