Ar is a colorless, odorless, and inert gas at room temperature. The name of the gas has been derived from the Greek word ‘argos’ which means idle or lazy. Argon was discovered in 1894 by Lord Rayleigh and Sir William Ramsay. The discovery was late despite the abundance of the gas due to its inert behavior. We are often under a misconception that O2, N2, and CO2 are the three most abundant gases, but Ar is the 3rd most prevalent gas in the atmosphere, accounting for ~1 % of the Earth’s atmosphere....

Is H2S Ionic or Covalent? H2S is a covalent compound because, according to Fajan’s Rules, the large size and greater charge on the sulfide anion (S2-) favor the formation of a covalent bond. The small electronegativity difference between the sulfur and hydrogen atoms also contributes to the formation of a covalent bond. H2S consists of two elements, Hydrogen, and Sulfur. Hence, it is a binary compound. Industrially, pure H2S is obtained by separating it from other constituent gases of natural gas....

Also, the application of air or H2O2 leads to oxidation of hydrazine ( N2H4, a colorless flammable liquid ) which results in the formation of N2H2. Below is the chemical equation of preparation of Dinitrogen Dihydride/Diazene/Diimide (NCOOH)2 ——> (NH)2 + 2 CO2 It melts at 193K and has a molar mass of 30.03 g/mol. It has a density of around 1.2 g/cc. Azo and diazo groups are substituents from diazene....

A radical is known to consist of an unpaired valence electron and therefore tends to be highly chemically reactive. This property makes this radical short-lived (unless treated with certain organic molecules). It has a molar mass of around 16.0226 g/mol and is the neutral form of amide ions or azanide ions. Here, in this article, we will focus on the azanide anion (NH2-). NH2- is the conjugate acid of hydridonitrate (H-N2-) and conjugate base of ammonia (NH3)....

It occurs as a diatomic gas and is also the third most abundant element in the universe. It is a colorless and odorless gas with oxidizing properties. Oxygen is required for several processes such as combustion, cellular respiration, etc. It also forms a part of many important organic molecules such as proteins, carbohydrates, nucleic acids, etc. Plants breathe out oxygen in the environment thus, replenishing it. Hey guys!!! Our topic for today is the Bohr model of oxygen....

A Phosphorus Pentachloride molecule consists of 1 atom of phosphorus for 5 atoms of chlorine. If we talk about the physical appearance of the compound, it is sensitive to water and moisture in its solid form, along with being colorless. While it being colorless, there have come to exist commercial specimen green and yellow in color upon being contaminated by Hydrogen Chloride (HCl). It is also found in its liquid and gaseous state wherein it depicts neutral properties....

It is a poisonous liquid that is known to act as a selective fluorinating agent especially in organic synthesis reactions. Valence Electrons The valence electrons are the electrons that are farthest from the nucleus of an atom i.e. the electrons that are present in the valence shell of an atom. These electrons actively participate in the chemical bonds that an atom forms with other atoms and are also given away (or taken up) from one atom to another in the case of ionic bonding....

It offers conduct, strength, affordability, toughness, and adaptability. Therefore, its usability lies in the construction of a wide range of structures. Does Concrete Absorb Water? Yes, Concrete does absorb water because it is actually a porous material made up of cement, sand, gravel with water. Concrete absorbs rainwater and water from the air during high humidity in the environment. Even after the mixture hardens, it remains porous in nature. Concrete goes through the process of mixing different varieties of sand, cement, gravel with water....

It is interesting to realize that the covalent bonds are stronger than the hydrogen bonds, that is the reason why water readily reacts with the majority of the chemical elements from the periodic table. The Lewis structure, or also called an electron dot structure, is a diagrammatic representation of determining the total number of valence electrons present in an atom, which are ready to undergo bond formation to form a molecule and ultimately a compound....

Formic acid was isolated from the distillation of ant bodies in earlier times and it is also produced from methanol industrially. The molar mass of formic acid is 46.03 g/mol and its boiling point is nearly equal to the water molecule i.e., 100.8 °. Formic acid is a colorless liquid with a pungent and penetrating odor. It is highly soluble in water and polar solvents. It exists as a hydrogen-bonded dimer in the vapor phase as well as in hydrocarbons....

So, is HCl polar or Nonpolar? HCl (hydrochloric acid) is a polar molecule because the chlorine is more electronegative than hydrogen due to which it attracts the bonded electron pair slightly nearer to it and gains a partial negative charge and hydrogen gains a partial positive charge. The dipole moment of HCl turns out to be 1.03 D. Hydrochloric acid is colorless in color and has a pungent odor. In the form of an aqueous solution, it is widely used in chemistry laboratories in high schools and universities....

So, is Steel magnetic? Some grades of steels are magnetic and some are non-magnetic. Martensitic steel consists of ferritic microstructure due to which it shows magnetic behavior whereas austenitic grades have nickel present in it and they do not show magnetic behavior. Therefore, different steels have different answers regarding magnetic properties. Let us read more about this variation of magnetic properties with different grades of steel in more detail! There cannot be a straightforward answer to this question....

So, is Titanium magnetic? Titanium is weakly attracted to magnets as it is a paramagnetic material. The main reason for its paramagnetic nature is its electronic configuration with 4 unpaired electrons, as paramagnetism depends on unpaired electrons. The second reason is its magnetic moment ie; 1.73 BM. Titanium is paramagnetic in its -1, +2 and +3 oxidation states. But it’s good to note that Titanium’s magnetic susceptibility is very small and positive making its magnetic property very weak compared to ferromagnetic materials....

In this article, we will study the basic concepts of prediction of Lewis structure, geometry, hybridization, and polarity. Lewis Structure It is the 2D representation of a molecule. According to this concept, only valence shell electrons participate in bonding, and hence only they are represented while drawing the lewis structure of an atom. Lewis structures are one of the primitive attempts for the explanation of bonding. Some compounds can have more than one Lewis structure....

It was first produced by Jean Baptiste Dumas in 1847. It is also a potent air pollutant found in automobile and industrial exhausts. In this article, we will study the lewis structure of CH3CN along with its geometry, hybridization, and polarity. Read till last. CH3CN Lewis Structure Lewis dot symbol or lewis structures are the diagrams that demonstrate the bonding between different atoms of a compound, specifying the number of bonds as well as the lone pairs of electrons....

The standards upheld by authorities require the brake fluid to be able to withstand the high temperatures generated in the system. Which means it should not evaporate rapidly. On the other hand, the fluid pulls moisture and has alcohol and esters in it. In theory, these two qualities make evaporation a possibility. If the thought has been bothering you, give the following discussion a try to clear things up. Brake fluid is an important part of driving safety....

Even in a technical point of view, white gold is more flexible and elastic which makes it easy to work with and turn them into beautiful and exquisite ornaments. However, when regularly used, white gold tend to turn yellow as time passes. Let’s take a few moments to understand the science behind these changes and how it can be prevented. So, does white gold tarnish? No, White gold neither gets tarnished nor gets oxidized....

Some people call these clouds fog. But not all dense white air is fog. It can also be mist. Like many people, you may also not know the difference between fog vs. mist. Although both fog and mist are formed by water condensation because of a sudden drop in temperature, there are some differences between these two. They do not have the same density, and the locations they form in also vary....
