Moreover, the polymer carbon diselenide is a good semiconductor with 50 S/cm electrical conductivity at room temperature.Carbon diselenide has a distinct odor, somewhat similar to carbon disulfide when comes in contact with air.As this compound is toxic to the human respiratory tract, it becomes essential to read about the mechanism behind its bond formation that can be studied only through its atomic structure. Lewis Structure of Carbon diselenide (CSe2) The Lewis dot structure is the starting point to understand the behavior of a compound at the molecule level....

So, does blood conduct electricity? Yes, Blood conducts electricity because it contains salt and water as its constituents and salt is an electrolyte. Salts present in blood ionize to conduct electricity through the blood.Blood is an essential part of a living body including humans, animals, and other organisms also. It is present in the form of a fluid that is essential for survival. The main function of blood is to provide oxygen to cells and tissues....

So, does saltwater evaporate? Yes, saltwater evaporates, leaving behind salt crystals. And the addition of salt in pure water decreases the rate of evaporation of the salt solution. This is because of the decrease in the saturation vapour pressure of the salt solution. Evaporation is directly proportional to the difference in vapour pressure of air in contact with the salt solution and the air at some altitude.Natural water bodies contain varieties of salts (sodium chloride, magnesium chloride, potassium chloride) in it....

So, Is Brass a Magnetic Compound? No, brass is not a magnetic compound. Dominant constituents of brass are copper and zinc, which are both non-magnetic. None of these compounds react with moving magnets, and hence their resultant alloy is also not a magnetic compound. It is considered a diamagnetic element. Magnetism and Magnetic Materials An object that can produce its own magnetic field is called a magnetic material. Magnetism depends on the motion of electrons and their interaction with each other....

So, is CF4 polar or non-polar? CF4 is a nonpolar molecule. Although all C-F bonds are polar because carbon and fluorine differ in their electronegativity, the overall CF4 molecule is non-polar. This is because of the symmetrical arrangement of all fluorine atoms around the central carbon atom. Therefore each individual C-F bond dipole cancels out each other resulting in the net-zero dipole moment of the entire molecule making it nonpolar....

So, is Copper magnetic? Yes, it is weakly magnetic in the presence of a large external magnetic field as it is diamagnetic in nature. Otherwise, copper is non-magnetic in nature. Being a diamagnet, copper repels an external magnetic field.The magnetic properties of any metal usually depend on the presence of unpaired electrons in the outermost shell.The more a merrier, as they help the atom with responding to a nearby magnetic field, either by attracting to it or getting repelled by it....

Many compounds with four substituents on silicon, including an organosilicon compound, are referred to as “silanes.”Most of the students wonder if silane is polar or non-polar. In this blog, I will give you clear answers to this question and discuss some concepts about polarity and the factors affecting it.So, is silane a polar or non-polar covalent compound? Let’s find out in the next section.The SiH4 is nonpolar in nature because of its symmetrical shape having four identical Si-H bonds canceling out their dipole moments resulting in net dipole moment zero....
