We assume you are converting between MOLES Boron and gram. You can view more DETAILS on each measurement unit: MOLECULAR weight of Boron or grams The molecular formula for Boron is B. The SI base unit for amount of SUBSTANCE is the mole. 1 mole is equal to 1 moles Boron, or 10.811 grams.

Ionic compounds conduct ELECTRICITY when molten (liquid) or in AQUEOUS solution (dissolved in water), because their ions are free to MOVE from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed POSITIONS and cannot move.Pls MARK as brillianest

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. Hybrid orbitals are very useful in the explanation of molecular GEOMETRY and atomic bonding properties and are symmetrically disposed in space. Although sometimes taught together with the valence SHELL electron-pair repulsion (VSEPR) theory, valence bond and hybridisation are in fact not related to the VSEPR modelExplanation:Mark me as BRAINLIST

The steady depletion of global energy resources due to increased consumption by mankind has contributed to the severe problem of exhausting all available non RENEWABLE energy resources such as natural GAS, oil and coal. As such, reversal of combustion reactions requires a considerable AMOUNT of energy.Thanks for the QUESTION. Hope it helps you.

1.a) metalloids are those elements which shows the the properties of both metal and nonmetal.TWO metalloids are boron and siliconb) COPPER aluminium Mercury and sodium are metalssulphur oxygen CHLORINE and nitrogen are non metalssilicon and GERMANIUM are metalloids2. When Sulphur dioxide is added to water the water becomes acidic in nature.HOTS1.a) Two METALS that can be behave like X are sodium and magnesiumb) the gas Y is hydrogen3. most reactive metal is zincmoderate reactive metal is ironleast reactive metal is copper

Explanation: :- Solution1) It is a homogenous MIXTURE. 2) It can be separated through evaporation.3) It is transparent. 4) For EXAMPLE- sugar+water Suspension1) It is heterogeneous mixture.2) It can be separated through filtration.3) It is opaque where PARTICLES are suspended.4) For example - soil+water. :- Collodies1) It appears to be homogenous but is actually heterogeneous mixture.2)It can be separated by centrifugation.3)It is translucent. 4) For example - Milk + water

Among the above given options, the correct option with HIGH GWP is C) CFC>N20>CH4>CO2.GWP is global warming potential of certain GASES. Global warming is the effect of green house gases, which traps heat and MAKES the earth's atmosphere warm with a relative rise in temperature. It is seen in approx 100 year time horizon that GWP Of CFC is 10900, N2O is 298, CH4 is 25 and CO2 is 1.All these green house gases are emitted due to the production in fossil fuel, deforestation, combustion, industrial process, refrigerator etc.

Explanation:OXIDATION number or oxidation STATE of an atom in a chemical compound is  the number of electrons lost or gained. It is also DEFINED as the degree of oxidation of the atom in the compound.This is a THEORETICAL number which can help to decipher the oxidation and reduction in a redox reaction.Carbon in methane, is in oxidation state of -4 and in carbon dioxide, , carbon is in oxidation state of +4. The chemical reaction is:

tion:The true SOLUTION is the homogenous MIXTURE, whileColloidal solution and SUSPENSION are the HETEROGENEOUS mixtures of two or more substances. Anotherdifference between these three TYPES of solution is that the True solution is transparent, while theColloidal solution is translucent and Suspension is opaque.

teCentrifugation is a technique which involves the application of centrifugal force to separate PARTICLES from a solution according to their SIZE, shape, density, VISCOSITY of the MEDIUM and rotor speed.

Three DOUBLE bonds in BENZENE are fully conjugated, therefore there is not any TRUE double bond at all. Because of this, there is also an alternative formula for benzene in which there are not double bonds. The circle represents its 6 delocalised π-electrons.Thanks for the question. HOPE it helps you.

ikov's RuleMarkovnikov's Rule STATES that whenever we add any protic ACID i.e. HX to any asymmetric alkene, then every time hydrogen i.e. H gets attached with the carbon and as a result there are more and more of hydrogen. Also, the halyde group i.e X group further gets attached to carbon and as a result there are many more alkyl form is resulted. To put this in simpler words, the total number of hydrogen atoms gets combined or added with carbon  and hydrogen atoms act in this and again when the X form is added, there are negligible AMOUNT of hydrogen atoms.

nails is placed in air TIGHT contaner the MOISTURE cannot ACT on iron nail so it prevent the rusting of iron. if we can put iron nale in outside weather there is OXYGEN and moisture which act on iron nail so there is pssiblety of rusting of iron.

Non-carbonate HARDNESS is the part of WATER TOTAL hardnessthat is not generated bycarbonates, but mainly by anions of sulfate. It is ALSO the MEASURE of magnesium and calcium salts apart frombicarbonate and carbonatesalts like magnesium chloride and calcium sulfate.

See in ncert BOOK lesson NUMBER 4 of carbon crystal STRUCTURE

n-carbonate HARDNESS is the part of water TOTAL hardness that is not generated by carbonates, but MAINLY by anions of SULFATE. It is also the measure of magnesium and calcium salts APART from bicarbonate and carbonate salts like magnesium chloride and calcium sulfate.hope it helps u mate#ammu

There are two broad TYPES of isomers: CONSTITUTIONAL and stereoisomers. Constitutional isomers differ in BONDING and CONNECTIVITY. Stereoisomers differ in 3D orientation. Enantiomers and DIASTEREOMERS are two sub-types of stereoisomers...thnq❣

Preparation of AlkanesAlkyl halides (except ALKYL fluorides) on reduction with zinc and dilute hydrochloric acid produce alkane. Haloalkanes (Alkyl halides) react with metallic sodium in dry ether to form SYMMETRICAL alkanes with DOUBLE the NUMBER of carbon atoms present in the alkyl halide. This reaction is known as Wurtz reaction.Thanks for the question. Hope it helps you.
