-NEWLANDS law of Octaves does not hold well for the ELEMENTS which lie beyond calcium. After calcium EVERY eighth element does not POSSESS the properties similar to the FIRST element. -The elements that are discovered later do not obey Newlands law of Octaves.

Yes its OxidationExplanation:But the atoms don't STAY single LONG: They quickly bond with oxygen in the air in a process called oxidation. When carbon bonds with oxygen, it PRODUCES carbon dioxide — a colorless gas. When hydrogen bonds with oxygen, it produces water vapor — even as the wood burns.Please mark me as Brainliest and ALSO Thank my answer

I am not ANSWER and THANKS me

Atoms of the transition ELEMENT are smaller than those of the s-block elements due to contraction in SIZE in periods and also new elctrons are ADDED to the PENULTIMATE d-shell rather than to the outermost shell of the atom.Hope it helps you

On Kelvin scale the temperature is set at -273.15 when it is ABSOLUTE zero, beyond which the temperatures cannot go. Thus, the scale UNLIKE others STARTS at zero which is the lowest temperature on the scale. As lowest value on the Kelvin scale is zero, hence all FIGURES are in positive value.

2.00 g of some unknown compound reduces the freezing point of 75.00 g of benzene from 5.53 to 4.90 ∘C . What is the molar MASS of the compound? Solution First we must compute the molality of the benzene solution, which will allow us to find the number of moles of SOLUTE dissolved. m=ΔTf−Kf=(4.90−5.53)∘C−5.12∘C/m=0.123m Amount Solute=0.07500kgbenzene×0.123m1kgbenzene=0.00923msolute We can now find the molecular weight of the unknown compound: Molecular Weight=2.00gunknown0.00923mol=216.80g/mol The freezing point depression is especially vital to aquatic life. Since saltwater will FREEZE at colder temperatures, organisms can SURVIVE in these bodies of water

Dyes: It is dye which has negative charge so they bind to positively charged CELL structures like some proteins. ACIDIC dyes are not very often used in Microbiology lab. except to provide background STAINING like CAPSULE staining. EXAMPLES: Nigrosine, Picric acid, Eosin, Acid fuschin, India ink etc.

HYDROGEN BONDINGMelting point of phenol (42 deg C) is relatively HIGH for an aryl compound because of the hydrogen bonding. The H atom of −OH group of one MOLECULE of phenol is involved in hydrogen BOND FORMATION with O atom of −OH group of second molecule of phenol.Explanation:

a. Seperating Funnel DENSITY of one liquid is greater than another (lighter liquid FLOATS on denser liquid)B. Fractional distillationevaporation point of one solid is greater than anotherc. Evaporationinsoluble SOLIDS in liquid do not get EVAPORATED along with liquid

A solid can be converted into liquid and then to gas by decreasing the pressure and increasing the temperature. A gas can be liquefied by increasing the pressure and decreasing the pressure. Same is the method for converting a liquid into a solid. Every state of matter of any substance is stable at a corresponding pressure and temperature. Thus, temperature and pressure determines the state of a substance.The pressure and temperature determine the state of a substance. Matter can exist in a solid, liquid or gaseous state, and the state a substance is in can be largely determined by its temperature.Phase changes occurWhen temperature or pressure change of a system OCCURS, phase changes occur. When the temperature or pressure increases, the interaction between the molecules increases. Similarly, when the temperature decreases, it is easier for molecules and atoms to settle into a more rigid structure.Effects of Pressure and temperatureTemperature is a MEASUREMENT of the average kinetic energy of the molecules. Pressure is also a factor when examining the effects of temperature on the various states of matter.According to Boyle’s Law, temperature and pressure are directly related, meaning that an increase in temperature results in a corresponding increase in pressure. This is again caused by the increase in kinetic energy associated with increasing temperature.At sufficiently low pressures and temperatures, solid matter may bypass the liquid phase and be converted directly from a solid to a gas through a process called sublimation.Changes that occur when pressure and temperature is variedOn increasing pressure On decreasing pressureParticles of matter COME closer.If pressure is frequently applied on a gas, particles of the gas come more closer and a stage is reached when gas may change into liquid.If pressure is INCREASINGLY applied on a liquid, it will change into liquid.On reducing pressure, particles of matter expand.If reducing pressure is applied on a liquid, it will change into gas.If reducing pressure is applied on a solid, it will change into liquid.On increasing temperature On decreasing temperature The kinetic energy of the particles increases.Due to the increase in kinetic energy, the particles start vibrating with GREATER speed.As a result, the particles leave their fixed positions and start moving freely.If temperature is increasingly applied on solid, it will change into a liquid state.On decreasing the temperature of any state, the particles come closerIf we apply reducing temperature on gas, it will change into liquid.If we apply reducing temperature on liquid, it will change into solid.

Hey MATE I think you should use tgis formula to find your ANSWER: Q = vAExplanation:Here, Q means: Volumetric flow RATE v means: flow velocity AND A means: cross selection VECTOR area.Hope you find it helpful.If you liked it please mark me as the BRAINLIEST.

In body-centred cubic unit cell (BCC) has atoms at each CORNER of the cube and an atom at the centre of the structure. The packing efficiency of the BCC lattice is 68%.The packing efficiency is the fraction of the CRYSTAL (or unit cell) ACTUALLY occupied by the atoms. It must always be less than 100% because it is impossible to pack spheres (atoms are usually SPHERICAL) without having some empty space between them.

Dilute sulphuric ACID will react to PRODUCE hydrogen gas. Increasing the concentration will increase the rate of REACTION. Since the product is in another PHASE (hydrogen is a gas) too rapid a reaction brings a risk of overpressurization and explosion.It is important that the hydrogen PEROXIDE solution is acidic. The hydrogen ions take part in the reaction as a reactant.It is also important to use sulfuric acid and not hydrochloric acid because the permanganate is such a powerful oxidant, it would oxidize chloride ions to form chlorine.

The general CHARACTERISTICS of Organic Compounds are: Organic compounds include complex STRUCTURES and high molecular weights. These are soluble in organic solvents and mostly insoluble in water. Mostly DEPEND on only three ELEMENTS: Carbon, Hydrogen and NITROGEN. These compounds are combustible in nature.
