In the Lewis THEORY of acid-base reactions, bases DONATE pairs of electrons and acids accept pairs of electrons. A Lewis acid is therefore any substance, such as the H+ ION, that can accept a pair of non-bonding electrons. In other WORDS, a Lewis acid is an electron-pair acceptor.

It is because non- METALLIC character increases from left to right ALONG a PERIOD.

The VALUE of R in SI UNITS is 8.314JK−1mol−1.

s=  2 1 ​ gt  2  s is DIRECTLY proportional to t  2  So the distances are in the ratio of SQUARES of INTEGRAL NUMBERS Explanation:

In the presence of light silver nitrate DECOMPOSE to form silver. hence to prevent the DECOMPOSITION it is kept in DARK coloured BOTTLES

ahajiwExplanation:white solid is heated, gas 'P' and Q are evolved LEAVING behind a solid residue R. P is an acidic gas which turns lime water milky. Q is a NEUTRAL gas which condenses into a liquid and turns anhydrous CUSO4 BLUE in colour. R is used for softening of hard water after recrystallisation of it. Gases P and Q respectively are -

A SOLUTION is a HOMOGENEOUS MIXTURE of one or more SOLUTES dissolved in a solvent.. Solute: the substance that dissolves in a solvent to produce a homogeneous mixture.

this is TAMIL or TELUGU I THINK so

Normally, oxygen solubility is STRONGLY dependent on (1) the AMOUNT of dissolved electrolyte salt(s) (DECREASES at higher concentration of electrolyte), (2) temperature (decreases at higher temperatures), and (3) pressure (INCREASES at higher pressure).

AnswerThree applications of coordination compounds:1. Zinc-complex enzymes LIKE carbonic ANHYDRASE important to buffering REACTIONS in blood. 2. Copper-complex enzymes important to iron STORAGE and producing pigments in HAIR, skin, and eyes. 3. Nickel-complex enzymes as part of the enzymes urease and hydrogenase.

Normality (N) is defined as the number of mole equivalents per liter of solution:normality = number of mole equivalents/1 L of solution. Like MOLARITY, normality relates the amount of SOLUTE to the TOTAL volume of solution; however, normality is specifically used for acids and BASES.

Phenol is an aromatic organic COMPOUND with the molecular FORMULA C₆H₅OH. It is a white crystalline solid that is volatile. The molecule CONSISTS of a phenyl group bonded to a hydroxy group. MILDLY acidic, it requires careful handling because it can cause chemical burns.Explanation:Hope it will helpful for you thanks.. ❤

A molecule consists of two or more atoms of the same element, or different ELEMENTS, that are chemically bound together. Note that the two nitrogen atoms which COMPRISE a nitrogen molecule MOVE as a unit. Microscopic VIEW of the molecules of the compound WATER (gas phase).

Alkenes are relatively stable COMPOUNDS, but are more reactive than ALKANES because of the REACTIVITY of the carbon–carbon π-bond. ... Because the carbon-carbon π bond is relatively weak, it is quite reactive and can be EASILY broken and reagents can be ADDED to carbon.

Condensation is the CHANGE from a vapor to a CONDENSED STATE (solid or liquid). Evaporation is the change of a liquid to a gas.Explanation:i hope it will help you

Vapour DENSITY is the density of gas with respect to the density of hydrogen at same temperature and pressure. You MEASURE density of the gas at, say p and at temperature T and divide it by the density of Hydrogen at the same temperature and pressure. The FORMULA you USED was only valid for an ideal gas.

Anisotropy, in PHYSICS, the quality of exhibiting PROPERTIES with different values when measured ALONG AXES in different directions. Anisotropy is most easily observed in single crystals of solid elements or compounds, in which atoms, ions, or MOLECULES are arranged in regular lattices.

Molarity of NACL = no of MOLES of NaCl / volume of SOLUTION in LITRES. Given mass of NaCl = 60G. Molar mass = 23+35.5=58.5g. No of moles = 60/ 58.5 = 1.026 moles.

After electrolysis:∵20.09g of anodic solution CONTAINED 0.06227 g of AgNO 3 ∴ Mass of water in solution =20.09−0.06227=20.02773gThus, 20.02773gH 2 O has 0.06277 g AgNO 3 = 1700.06227 equivalentAgNO 3 =0.0003663equivalentAgNO 3 or Ag + Before Electrolysis:∵10.0g of solution contained 0.01788 g AgNO 3 ∴ Mass of water in solution =10−0.01788=9.98212gThus, 9.98212 g water has =0.01788 gAgNO 3 = 1700.01788 eq.

Molality is independent of temperature and PRESSURE. Molarity and Normality DEPENDS on the volume, which is dependent on the Pressure and Temperature. But, Molality is expressed in TERMS of MASS of solute, which is independent of temperature and pressure. Wherever the volume TERM appears in the expression of concentration, it will depend on Pressure and Temperature.

The sulfate or SULPHATE ION is a polyatomic anion with the EMPIRICAL formula SO²⁻ ₄. Salts, acid derivatives, and peroxides of sulfate are widely USED in industry. Sulfates occur widely in everyday life. Sulfates are salts of sulfuric acid and MANY are prepared from that acid.
