The primary difference between organic chemistry and inorganic chemistry is that organic compounds mandatorily have a carbon atom, while most of the inorganic compounds do not contain a carbon atom.
Inorganic chemistry is mostly concerned with the properties and behavior of the inorganic compounds, which include minerals, metals and organometallic compounds.
Inorganic chemists are employed in fields ranging from mining to microchip making. The works are based on understanding the following:
The behavior and analogues for the said inorganic elements, and How these materials can be separated, modified and used.On the other hand, Organic chemistry is the study of the properties, structure, composition, preparation and reactions of carbon-containing compounds. Most organic compounds contain carbon and hydrogen together, but they may also include any number of other elements too (e.g., nitrogen, oxygen, halogens, phosphorus, silicon, sulfur).
Organic chemists spend most of their time developing noval/new compounds and finding better sustainable ways of synthesizing existing ones.

T/F All amino acid based hormones are lipid soluble and can cross the plasma membrane.
False All the amino acid based hormones are not lipid soluble and can not cross the plasma membrane.
Amino acid-derived as well as polypeptide hormones are water-soluble and insoluble in lipids. These hormones cannot pass through the plasma membranes of the cells; therefore, their receptors are found on the surface of the target cells.
Amino acids are those molecules which will combine to form proteins. When the proteins are digested or broken down, amino acids will be left. The human body uses amino acids to make proteins to help out the body: Repair body tissue, Grow, and Perform many other body functions.
Amino acids are also be used as a source of energy by the body.

Is bf3 polar or non polar?.
The B-F bond is polar. In order to understand why BF3 is polar, it is important to first understand its molecular geometry. BF3 has a trigonal planar shape, which means that it has three atoms bonded to a central atom in a flat, triangular arrangement.
In this case, the central atom is boron (B) and the three bonded atoms are fluorine (F).
The B-F bond is polar because Boron has a lower electronegativity than Fluorine. This means that the electrons in the bond will be more attracted to the Fluorine atom, giving it a partial negative charge and the Boron atom a partial positive charge.
This creates a dipole moment in each B-F bond.
Since the three B-F bond dipoles are arranged in a plane with an angle of 120 degrees between them, the dipoles cancel each other out, resulting in a net zero dipole moment and making BF3 a polar molecule.
However, it is important to note that the polarity of a molecule doesn't always depend on the dipole moment, but also on the symmetry of the molecule.
BF3, although has a net zero dipole moment, symmetry is not perfect. The three bond dipoles are arranged in a plane, but they are not equal in magnitude and direction. This creates an overall molecular dipole moment, making BF3 polar.

If metal X is lower then metal Y in the activity series, then what would happen?
Metal X replaces Metal Y ions in a solution because it is lower in the activity series than Metal Y. It is a single displacement reaction.
Metal X is above Metal Y in the reactivity series when replacing Metal Y from its respective salts.This replacement is guaranteed since X has a greater reactivity power than Y. If it were less than Y, it wouldn't cause a reaction since it wouldn't move Y.
A single replacement reaction, also known as a single displacement reaction, occurs when one element in a molecule is swapped out for another. Starting ingredients are always pure elements combined with an aqueous compound, such as pure hydrogen gas or zinc metal. A new aqueous compound and a different pure element will be produced as products when a replacement reaction takes place. Below is a general representation of a single replacement reaction.

Is chcl3 polar or nonpolar?.
Chloroform ([tex]CHCl_{3}[/tex]) is a polar molecule due to its asymmetrical shape.
The asymmetrical shape of the molecule [tex]CHCl_{3}[/tex] arises from the presence of the chlorine atom, which has a higher electronegativity than the hydrogen atoms.
This results in the chlorine atom having a partial negative charge and the hydrogen atoms having a partial positive charge.
This unequal distribution of charge gives the molecule a permanent dipole moment, making it a polar molecule and hence chloroform is not a nonpolar molecule.
Additionally, due to the large difference in electronegativity between the chlorine and hydrogen atoms, the molecule exhibits significant dipole-dipole intermolecular forces, which further reinforces its polarity.

what is the purpose of adding alum to water during the water treatment process?
The benign liquid alum (aluminium sulphate) is frequently used in water treatment facilities to clear drinking water.
It has been utilised in lakes since the early 1970s to lessen the phosphorus content of the water.
Alum dissolves in water and makes the pollutants in suspension heavier, causing them to settle down more quickly. So, loading refers to the addition of alum.
The most frequent use of alum in water treatment is as coagulants. Impurities were made larger by coagulants so they would settle in the sedimentation tanks. Pathogens found in the water can be killed by alum as well.
It facilitates sludge settlement in the secondary clarifiers, which improves the efficiency of the recycled water treatment process by allowing for the passage of cleaner, less turbid water. Additionally, struvite does not accumulate inside the digesters as a result of the alum in the effluent.

compare the size of ions to the size of atoms from which they form
Cations are always smaller than the atoms from which they form. Anions are always larger than the atoms from which they form. Ions are usually bigger than the atoms from which they are formed.
When an atom receives or loses electrons, the atom's electron configuration changes, resulting in a net positive or negative charge.
This net charge expands the electron cloud surrounding the nucleus, making the ion bigger in size than the neutral atoms from which it arose. When a metal atom loses one or more electrons to create a cation, it shrinks in size because the positive charge of the nucleus pulls the remaining electrons more strongly.
When a nonmetal atom obtains one or more electrons to create an anion, it normally expands in size.Because of the increasing amount of electrons, the electron cloud surrounding the nucleus grows. It should be noted that this comparison is not absolute and is dependent on the individual factors involved. Some ions are smaller than their neutral atom counterparts, while others are similar in size.

Place each noble gas symbol in front of the appropriate partial electron configuration to create an accurate electron configuration.
An electron configuration that is complete up to a certain partial electron configuration must exist in the noble gas that comes before it.
When fully written out exactly before the partial electron configuration, the electron configuration of the noble gas should provide us with a reliable electron configuration for some element.
Our noble gas should at least be in the third period as the highest principal energy level in the first series bears the number 4. (numerically, the energy level is the same as the period number). Argon would be that noble gas. Note: All noble gases have an electron configuration that contains Np6, where N is the greatest main energy level. The partial electron configuration provided is not that of a noble gas.
Therefore, [Ar] serves as the noble gas that suitably comes before our first partial electron configuration.
The electron configuration of argon is1s²2s²2p⁶3s²3p⁶.. By applying the Aufbau Principle, 4s2 would naturally come after 3p6. Writing out t 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p²; is identical to writing [Ar]4s23d104p2, which also happens to be the electron configuration of germanium.
