tion:To sum up, ether is a CHEMICAL with an oxygen atom bound to two alkyl GROUPS. Ethers are LIQUID at room temperature and are TYPICALLY colorless, with a SWEET smell. The most common type of ether is diethyl ether, which is extremely flammable and was one of the first anesthetics used in surgery.

tion:18000 cm3 H2S X 1 L/1000 cm3 x 1 mol/22.4 L = 0.804 moles of H2S 0.804 moles x 6.02x10^ 23 MOLECULES/mole = 4.8x10^23 molecules.

Solids which comprises or consists of a cation (a positive ion) and an ANION (a negative ion) can be termed as IONIC Solids. Those solids are held together by electrostatic forces. On dissolving, it dissociates into ions and MOVES freely in the solution. An EXAMPLE of an ionic solid is table salt, NaCl.

D block elements have a high number of unpaired electrons in their orbitals. This contributes to a greater number of electrons in the sea of electrons present in the crystal lattice THEREBY INCREASING the strength of the METALLIC bonds between the ATOMS.

I HOPE IT HELP YOU..Explanation:In chemistry, orbital HYBRIDISATION (or hybridization) is the concept of mixing ATOMIC orbitals into new hybrid orbitals (with different energies, SHAPES, etc., than the component atomic orbitals) suitable for the pairing of ELECTRONS to form chemical bonds in valence bond theory.

Chemical bonds are forces that hold atoms together to make COMPOUNDS or molecules. Chemical bonds include COVALENT, POLAR covalent, and ionic bonds. Atoms with relatively similar electronegativities SHARE electrons between them and are connected by covalent bonds.A chemical bond is a lasting attraction between atoms, ions or molecules that enables the ... These bonds exist between two particular IDENTIFIABLE atoms and have a direction in space, allowing them ... In this type of bond, the outer atomic orbital of one atom has a vacancy which allows the addition of one or more electronsKindly mark me as brainliest....plzzzhope u like my answer..

tion:Anomalous behaviour of WATER can be demonstrated with the HELP of HOPE's apparatus. ... (d) As temperature of water falls below 4∘C, water expands instead of contracting and its density decreases. So, water goes up from the centre portion. (E) As density increases, the cold water goes to the BOTTOM.

is an organic chemical compound with the molecular formula C₆H₆. The benzene molecule is composed of six carbon ATOMS joined in a PLANAR ring with ONE HYDROGEN atom attached to each. As it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon. In 1931, German chemist and physicist Erich Hückel proposed a theory to help determine if a planar ring molecule would have AROMATIC properties. His rule states that if a cyclic, planar molecule has 4n+2 π electrons, it is considered aromatic. This rule would come to be known as Hückel's Rule.

Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use MAY be drinking, INDUSTRIAL water supply, irrigation, river FLOW maintenance, water recreation or many other USES, including being safely RETURNED to the environment

solution prepare = 10% =10/100 =1/101/10= X/ 100 x = 1/10*100 =10 so amount of suger ADD is EQUAL to 10G

tion:Anodes needs to be REPLACED during the electrolysis of the ALUMINA because they gets oxidized. During the Electrolysis of the Alumina, Oxygen is deposited at the ANODE. Now, Anode is made up of the graphite (or Carbon), thus carbon REACTS with the Oxygen and forms its oxide.

The proton is located in the center (or nucleus) of an ATOM, each atom has at least ONE proton. PROTONS have a charge of +1, and a mass of APPROXIMATELY 1 atomic mass unit (amu).

tion:ATOMS are SINGLE neutral PARTICLES. MOLECULES are neutral particles made of two or more atoms BONDED together.

Not only does it make teeth stronger and prevent cavities, it can also help reverse EARLY TOOTH decay. When tooth enamel is weakened by acid, fluoride promotes a chemical reaction that REPLACES MINERALS, such as calcium and phosphate, to strengthen the enamel. This also makes it more resistant to FUTURE acid attacks.Explanation:HOPE IT HELPSPLEASE FOLLOW MEHAVE A GREAT DAY
