While the flame is believed to help drive away evil FORCES and NEGATIVE energies, camphor has many other benefits. Here's how you can USE it to purify your home. Camphor helps KILL germs, and it can be EXCELLENT to purify the air in the atmosphere.Explanation:Plz mark brainlist

The stability of HYDRIDES decreases down the group from NH3 to BIH3 due to decrease in their bond DISSOCIATION enthalpy which result in the increases of reducing character. Reducing character is directly related to the ease of losing hydrogen. ... Hence lose of hydrogen is easy and reducing nature increases down the group.

elements are of various TYPES and are vastly used for HUMAN welfare.Examples are-Gold- used as an ornamental elementAluminium- used in different INDUSTRIES like AIRCRAFT,electric,utensils,and so on.Iron- used to make various THINGS like rods and equipmentsHydrogenOxygen- life gasan so on.....

n difference is fractional distillation is USED to separate liquids with closer boiling POINT while simple distillation is used to separate liquids with boiling point GAPS of at LEAST 50 degrees. While simple distillation used a flask and condenser ...

Sc & zn belongs to 3rd group pf periodic table. The extent of metallic bonding an element undergoes DECIDES the ENTHALPY of atomization. The more extensive the metallic bonding of an element, the more will be its enthalpy of atomization. In all transition metals (except Zn, electronic configuration: 3d10 4s2), there are some UNPAIRED ELECTRONS that ACCOUNT for their stronger metallic bonding. Due to the absence of these unpaired electrons, the inter-atomic electronic bonding is the weakest in Zn and as a result, it has the least enthalpy of atomization.

The correct answer is OXYGEN... Hope it HELPS u....

ment which has both GASEOUS and sedimentary CYCLE cycle in NITROGEN OXYGEN and Carbon

Take some water(solvent) and keep it at a boil. Add tea leaves and a solute{sugar} and LET it boil. When small bubbles APPEAR add milk. Let the milk mix and let the tea COME up then cut the heat supply. USE a tea strainer(filter) to separate tea from resideu. Your yea is ready

ron METAL is exposed in moist air and the rusting of iron take PLACE seach such that if FE plus O2 Plus H2O GIVES the fe2o3 xh20

5.5 is the PH VALUE when the TOOTH DECAY

the ATOMIC MASS of an element is also called RELATIVE atomic mass because the DOUBLE of atomic mass is EQUAL to relative atomic mass

the SOLUBILITY of solute INCREASES on heating. Hence sugar dissolves FASTER in warm water than COLD water

So that it BURNS PROPERLY.

tion:in his structure he can't give EXPLANATION of the expand of octat . example PF5,H2SO4 some have ODD electron molecules . example N=Osome element EXHIBIT with incomplete octat

due to hydrogen bondingExplanation:the phenols and alcohol undergo extensive hydrogen bonding. This MAKES them more condensed to each other, HENCE the molecules are not ABLE to evaporate EASILY, as their bulk mass increases.

organic CHEMISTRY is related to carbon and atoms protons etc... while inorganic is related to chemicals PERIODIC TABLES physical matter in solid LIQUID and gasExplanation:organic as the NAME suggests is not living nature and similarly inorganic is non living

Hope it HELPS you EXPLANATION:Please MARK as BRAINLIEST

tion:For the acid and base just check the no. Of H+ or OH- ions in the reaction. For example.. HCl +NAOH gives H20 + Nacl In the above example one H+ change or you can say 1 OH- is change Hence the VALENCE FACTOR of HCl is 1 and the valence factor of NaOH is ALSO 1.

because body heats up and works fast there is a huge quantity of ENERGY produced as also the rate of BREATHING because oxygen plays an important ROLE in it plzz follow MARK as brainliest

r,Surface area of an object affects the rate of heat being transferred,emitted or absorbed.In freezing ,thermal energy is being lost. »» 'Larger the surface area of a substance,more is the TIME taken for it to freeze'.«« »» 'SMALLER the surface area of a substance,less time it takes to freeze.'««If u pour some water in a GLASS and put it in a freezer and at the same time pour some water in a larger bowl and also put that in a freezer,u will notice after sometime that in this PERIOD of time the water in the glass has frozen whereas the water in the bowl is still a bit in liquid form.This is bcuz of the difference in surface areas. Bowl water,having a greater surface area freezes slowly and opposite is the case with the glass water which freezes quickly or ghastly than the bowl water DUE to a lesser or smaller surface area.HOPE IT HELPS UH!HAVE A GREAT DAY AHEAD«««

NoExplanation:EQUILIBRIUM CONSTANT is only DEPEND on the TEMPERATURE

The electrons in d subshell have in SIGNIFICANT SCREENING effect. thus leading to a SUBSTANTIAL increase in effective nuclear charge . hence despite having more number of shells GALLIUM has a LESS atomic radius than aluminium.

illed and half filled orbitals are exceptionally STABLE than any other configurations for an atom. In some cases like COPPER and chromium the electrons even leave the usual filling pattern for having an half or fully filled orbitals.The famous quote of de BROGLIE goes likeNature loves symmetry.In half and fully filled configurations for an orbitals there more possibility  for an electron to exchange its position with another degenerate electron. More possibility means more exchanges happening in that atom releasing more energy, PARTICULARLY called exchange energy, hence ACCOUNTING for that extra  stability.

the particles OS solid are very CLOSE and TIGHTLY PACKED...... Plz mark my answer brainlist..

Their E values GET progressively more positive. Copper forms its ions LESS readily than hydrogen does. ... A major change is that copper is the more positive (less NEGATIVE) electrode. The voltmeter shows the hydrogen electrode as the negative ONE and the copper electrode as positive.

tion:ELECTRODES. For precision measurements of conductance platinized-platinum electrodes are used to REDUCE the POLARIZING effect of the PASSAGE of the CURRENT between the electrodes.

tion:when curd and sour substances kept in copper and brass vessels curd REACTS with copper it FORMS toxic compounds which MAY be unfit for human CONSUMPTION , and may CAUSE food poisoning.

d,LOOKS LIKE u FORGOT u to list down the options.Apna question retype kro and this time include the options plz

EvaporationExplanation: when we evaporate the SOLUTION of sodium CHLORIDE with WATER , the water will evaporate and sodium chloride will remain in the CONTAINER.

the second LAW of CHEMICAL combination is followed in BALANCED chemical EQUATION

tion:The chemical formula of washing soda is Na2CO3, and its chemical name is sodium CARBONATE. It is also known as soda ASH or soda crystals.In the following three STEPS, washing soda is prepared from sodium chloride or common salt. FIRSTLY, a cold and concentrated sodium chloride solution is reacted with ammonia and carbon dioxide to obtain sodium hydrogen carbonate. ... On heating sodium hydrogen carbonate decomposes to form sodium carbonate hope its clear to u...plz mrk me as BRAINLIST...

e their is your ANSWER....Electrolytic decomposition may result when electric current is passed through an aqueous solution of a COMPOUND. A good example is the ELECTROLYSIS of WATER. ...
