ting POINT of CUCL is LESS than NaCl because the difference between electronegativities of Na and Cl is greater than that of Cu and Cl. So the bond between Na and Cl will be more ionic and greater ENERGY will be required to break the bond. Thus, CuCl has a lesser mp than NaCl.Hope it helps :)

mal hot water can be used for many applications that require heat. Its CURRENT uses INCLUDE heating buildings (EITHER individually or whole towns), raising plants in GREENHOUSES, DRYING crops, heating water at fish farms, and several industrial processes, such as pasteurizing milk.

ter is a sample of ground WATER which freely lathers with SOAP solution meanwhile hard water is a sample of ground water which forms sticky SCUM with soap solution.temporary hardness is caused by hydrogen carbonates of magnesium and calcium. permanent hardness is caused by SULPHATES and chlorides of calcium and magnesium.temporary hardness can be removed by boiling it but permanent hardenss can be removed by TREATING the water with sodium carbonate.

A PHOTON can be defined as QUANTUM of energy. It is an elementary particle.Elementary particle is a particle that does not have a substructure.Elementary particles are the building blocks of the universe from which all other particles are made.The photon is the quantum of electromagnetic radiation (e.g. radio, light,x-rays, gamma rays) or the basic unit of light.Quantum :Quantum can be described as measure of quantity.Quantum is considered to be a discrete PACKET with energy stored in them.A quantum is a unit in which waves are absorbed or emitted. Quanta are the smallest units of something allowed.In short, its just a smallest, indivisible, discrete PIECE of anything.Difference :A photon has the properties of both wave like and particle like, but quantum does not.Quantum can be described as a measure of quantity, but a photon is not about a measure of quantity.WHY ??? Because…A photon can be defined as a quantum of energy / light.We think of light as being continuous, almost like a fluid, in our EVERYDAY experience, but on small enough scales, light can be thought of as particles.On those scales, there's no such thing as "less light" coming from something. It either gives off 1 photon, or it gives off no photons, but there is no in between.A photon is a quantum but not all quanta are photons.

e help of a diagram,explain cleansing ACTION of soap.Soap molecule form structures called micelles where one end is towards the oil droplet while the ionic end FACES outside. ... Thesoap SOLUTION thus helps in dissolving the DIRT in water and we can wash the clothes CLEAN. OR Explain the cleansing action of soapWhen soap is dissolved in water, its hydrophobic ends attach themselves to dirt and remove it from the cloth.First, the molecules of soap arrange themselves in micelle formation and trap the dirt at the centre of the cluster.These micelles remain suspended in water like particles in a colloidal solution.

e molecules are triatomic and there is electronegativity difference between C-O as well as O-H. But their polarity difference indicates that their structures are DIFFERENT. The difference in polarity is due to the symmetries of the molecules. Since CO2 is non POLAR and central atom has no lone PAIRS, it shows that both of the oxygen atoms are on opposite sides of carbon thereby cancelling the dipole moment and making the molecule linear. H2O being polar indicates that both the hydrogen atoms are on one side and the lone pair of electrons on the central atom is on the other side and due to BOND pair-lone pair repulsion , the GEOMETRY of the molecule is bent. The contribution in the polarity is the dipole moment from the lone pair.

te☺❤heres ua answerDue to the presence of a lone pair of electrons on carbon in CO, it acts as a Lewis base (or ligand) and thus forms a soluble complex with ammoniacal cuprous chloride solution.On the other hand,CARBONDIOXIDE does not act as a Lewis base since it does not have a lone pair of electrons on the carbon ATOM and hence, does not DISSOLVE in ammoniacal cuprous chloride solution.hope it helped uh.....
