But it is not true as the presence of the left small percentage of other elements, alter the magnetic properties of hematite. The electronic configuration of the involved chemical plays an essential role in determining the magnetic properties of hematite. It is the atomic movement of hematite at different temperatures that leads to magnetic property in it. We need to discuss this in detail within this article. Is Hematite Magnetic?...

But first, let’s slow down and clarify a few things. KOH is the chemical formula for potassium hydroxide and the key to answering all our questions.But why is KOH so ever-present?And what does KOH do?Is KOH an electrolyte? Yes, KOH is a strong electrolyte as it completely dissociates into K+ and OH- ions in an aqueous solution or in the molten state. It easily conducts electricity through its aqueous solution due to the presence of free ions....

LiOH can be prepared by reaction of Li metal or LiH, lithium hydride with water. It exists in the monohydrate form at room temperature and loses the water of crystallization at 423 K (150oC).2Li + 2H2O → 2LiOH + H2 ↑Another method for the preparation of LiOH is by the reaction of lithium carbonate with lime.Li2CO3 + Ca(OH)2 → 2LiOH + CaCO3So now the question arises whether LiOH is a strong base....

So, is Tungsten Magnetic? Yes, Tungsten is partially magnetic or paramagnetic in nature because of the presence of unpaired electrons and realignment of those electron paths because of an external magnetic field. Therefore, it is weakly attracted by magnetic. What is Paramagnetism? Paramagnetism is a form of magnetism where some elements are weakly attracted by an external magnetic field and form its magnetic field in the same direction of the applied external magnetic field....

On the commercial level, magnesium fluoride is formed when magnesium oxide reacts with any hydrogen fluoride (like ammonium bifluoride).The reaction is mentioned belowMgO + (NH4)HF2 —–> MgF2 + NH3 + H2OBeing an important commercial compound, let’s study the Lewis structure and various chemical properties it shows because of valence electrons behavior. What is Lewis Structure? We can study the bonding between atoms of different molecules and the number of lone pairs of electrons within a molecule....

It is polar because of the presence of two chloro groups but is not miscible with water; however, it does show miscibility with various organic solvents such as chloroform, carbon tetrachloride, hexane, benzene, ethyl acetate, and alcohols.The preparation of CH2Cl2 involves a high-temperature treatment of methane or chloromethane with chlorine gas.CH2Cl2 is considered toxic; its overexposure via inhalation leads to dizziness, nausea, numbness, and weakness. It is also metabolized in the body to form carbon monoxide and can cause poisoning....

Motor oil does go bad after a certain period. It has a shelf life of around 5 years if it has not been opened. But it is preferable to utilize the oil within a year of opening the bottle. Otherwise, the oil might go bad even before the expiration date ends.Well, it is not as simple as only checking the expiration date to know if the motor oil has gone bad....

Does Sterling Silver Rust? No, sterling silver does not rust because there is no iron content in the sterling silver. But it gets tarnish forming a black layer of sulfide or oxide on its outer surface. Sterling silver is an alloy of 92.5% of silver and 7.5% of other metals mainly copper that gets tarnish over time if exposed to air.Rust is a reddish-brown iron oxide, which forms when iron, reacts with oxygen in the presence of air and moisture....

In pure form, it is known as glacial acetic acid and is known to be corrosive in nature.Many of us are confused if acetic acid is a weak or a strong acid. Today, in this article, I will make you familiar with the concepts regarding weak acids.So, let us start with the basics of Acetic acid.So, is acetic acid a strong acid? Acetic acid is a weak acid as it does not completely dissociate into its constituent ions in an aqueous solution and forms a miscible mixture with water....

The term alcohol is referred to the four types of alcohols, namely, ethyl alcohol, denatured alcohol, isopropyl alcohol, and rubbing alcohol.Out of these four alcohols, ethyl alcohol describes the term alcohol efficiently. It is also known as ethanol (common name) and grain alcohol as it is obtained from the fermentation of fruits, grains, or sugar. Ethanol is used in the synthesis of drugs and it is also present in various alcoholic drinks....

Biofuels have the potential to reduce greenhouse gas emissions while also being renewable energy sources.Biofuel is renewable. This is because you can renew them at the same rate as you use them. Hence, biofuels can be made from live feedstock and organic waste, and they are a good way to recycle waste and reuse it in a useful way. They consist of water resources, land, and food resources. Thus, switching to biofuel is definitely going in the right direction....

The finish looks amazing and not tacky at all, and plenty of people are using it to decorate their homes. But is contact paper waterproof?Yes, contact paper is waterproof. This is because it’s made of PVC Vynil. Not only that, but some of the better quality contact paper is also heat resistant. This is why they are so popular for kitchen countertops or even in the bathroom. They take water well and do not get damaged by it....

So, Is H2O polar on nonpolar? Yes, water (H2O) is polar. This is because of the bent shape of the water molecule due to which there is an unequal charge distribution over the atoms of hydrogen and oxygen involved in the molecule of water. Therefore, the water molecule possesses a net dipole moment. Being a tasteless and odorless liquid compound at room temperature, water has a special property to dissolve plenty of other substances as a versatile solvent essential to living beings in the world....

It is an inorganic ion usually formed as a waste product of the metabolic system of different animals. It is used in the production of fertilizers, explosives, etc. The excessive presence of ammonium ions in soil may cause acidification.In this article, we will learn more about NH4+ and its different properties.So let’s begin…Is NH4+ an acid?Yes, NH4+ is an acid.

In this article, I’ll explain the answer to this question in detail and we will try to learn about the chemical structure of the O3 molecule.So, is O3 polar or non-polar? O3 is a polar molecule and it is due to its bent molecular geometry. In O3, the electric dipole moments of the bonds don’t counterbalance one another which results in a net dipole moment. Due to this, O3 (Ozone) is polar in nature....

The melting point is different for different polymorphs. It is pretty common in the earth’s crust and is even found in the green leafy vegetables we eat. The regular Glass that is used in windows, crockery is majorly SiO2. It is white or colorless, odorless, and tasteless.In this article, we will look at the polarity of SiO2, discuss the factors affecting it.
