The molar mass of iron (iii) oxide (Fe₂O₃) is 159.7 g/mol. the correct way to write the molar mass of iron oxide as a conversion factor is :

159.7 g Fe₂O₃/ 1 mol

The molar mass of Fe₂O₃ = 159.7 g/mol

molar mass of the substance is the mass in grams per mole of a substance.

the molar mass of Fe = 55.8 g/mol

the molar mass of O = 16 g/mol

the molar mass of Fe₂O₃ = 2 × 55.8 + 3 × 16

                                         = 159.7 g/mol

the molar mass of Fe₂O₃ = 159.7 g/mol

the correct way of write the molar mass of Fe₂O₃ = 159.7 g Fe₂O₃/ 1 mol.

When all of the copper has precipitated out of solution, the usual method is to conduct a visual check. Pure copper(II) sulfate is described as white. It is also known as anhydrous copper(II) sulfate because it does not contain any water. When water is present, a copper(II) sulfate sample turns blue. Free iron, which is typically transferred onto a part's surface during manufacture with steel components, is found using the copper sulfate test. Copper(II) ions in solution absorb red light from the spectrum. The light that emerges from the solution will contain all the colors except for red.

There are eight electrons needed for a full shell.

Atoms are most stable and least reactive when their outermost electron shells are full. Most of the elements important in biology require 8 electrons to be stable in the outermost shell, a rule of thumb known as the octet rule. Their outermost shells can only hold 8 electrons, so there are only 8 elements in both periods.

The full valence shell is the most stable electronic configuration. Other groups of elements have partially filled valence shells and gain or lose electrons to achieve stable electronic configurations.

Gibbs Free Energy, at any moment, is defined as the system's enthalpy less the product of the reaction's entropy and temperature, or:

ΔG° = ΔH° - T.ΔS°

Internal heat that exists in the system is referred to as enthalpy. It is determined by:

H° is equal to H°product - H°reagent.

Enthalpy Formation is used Table:

ΔH°= [3*(-299.9)+(-524.7)] - (-1277) (-1277)

Adding more substrate, more enzyme and adjusting the pH to the optimal level will increase the rate of the enzymatic reaction.

When we increase the enzyme concentration, more and more substrate are reacted and hence the rate of the reaction is increased.

Also, when the substrate is present in a large amount the enzyme works more efficiently because it has more allosteric sites to binds to.

As the enzymes are pH as well as temperature specific, the activity of the enzyme highly depends on the pH value, so, adjusting the pH to optimal level and freezing will decrease the activity of the enzyme.

This can be done by replacing the existing sentence with the new sentence, or simply adding it as an additional statement.

The photoelectric effect, first explained by Albert Einstein in 1905, is the phenomenon in which electrons are emitted from the surface of a metal when light of a certain frequency, or energy level, is shone upon it.

The photoelectric effect was first observed by William Hallwachs in 1887. Hallwachs observed that when light was shone on a metal, an electric current was produced. This current was proportional to the intensity of the light and independent of its frequency, leading him to conclude that the energy of the light was being transferred to the electrons in the metal.
