Atomicity atomicity is no of atoms EXAMPLE in S8. atomicity of sulpher is 8 in P4. atomicity is 8 atomic no atomic no is prolsed by mosely . misely was tge scientist whichmproposed periodic table by doing his x ray expeiment. atomic no. is. no of protons in ELEMENT it is not EQUAL to no of electrons in some species like charged species exame O2-. no of protons same but no of elecrrons dufferent from parent atom . but you know atomic no is not changed so we define atomic no as no of protons becayse protons arw inside the nucleus. charged on species is defined by deficiency or excess of protons if no of protons more than electrons then specie is positively charged PLEASE MARK me as brainliest

From sodium peroxide (Merck’s METHOD)Calculated amount of sodium peroxide (Na2O2) is gradually added to an ice-cold solution of 20% H2SO4 in small lots with constant stiring.Na2O2 + H2SO4 → Na2SO4 + H2O2Upon cooling, crystals of Na2SO4.10H2O separate out and the resulting solution contains about 30% H2O2. The solution also contains some dissolved Na2SO4, but it does not interfere with the reactions of H2O2. A pure sample of H2O2 may, however, be prepared by VACUUM distillation.2. From barium peroxide-Laboratory method of preparation.Hydrogen peroxide is prepared from barium peroxide by the following METHODS:(a) By the action of dilute sulphuric acid. Apaste of HYDRATED barium peroxide (BaO2.8H2O) is prepared in ice – cold water and then added slowly to an ice-cold solution of 20% H2SO4.BaO2.8H2O + H2SO4 → BaSO4 + H2O2 + 8H2O The white precipitate of BaSO4 is REMOVED by filtration leaving behind a dilute solution (5%) of H2O2. In this method, anhydrous barium peroxide can not used since the precipitated BaSO4 forms a protective layer around unreacted barium peroxide thereby preventing the further reaction

Because heavy water is a FORM of water that contains a LARGER than NORMAL amount of the hydrogen isotope deuterium rather than the common hydrogen-1 isotope that MAKES up most of the hydrogen is normal water.

Molar heat capacity is the AMOUNT of heat required to raise the TEMPERATURE of 1 MOLE of a substance by 1 unit & is calculated by dividing heat capacity by the total NUMBER of moles.Explanation:

because they can easily react with water and DISSOCIATES to form HYDROGEN GAS and hydronium IONS.

hii mate... No, marine water fishes can not LIVE in DISTILLED water because distilled water has no SALT, and that all sea creatures can only live in salt water. Distilling REMOVES all the impurities by filtering it, and it would TAKE out all the salt. And fishes require salt to live.... hope it helps you

here is answerExplanation:The elemental HYDROGEN reacts with “other SUBSTANCES” at slow rate in the “ROOM TEMPERATURE”. It is because the H-H “bond dissociation enthalpy” is highest for breaking one “single bond” between “two atoms” of any element. ... Apart from this, the bond enthalpy is ALSO high in hydrogen.

The most important property of an indicator is its PH range, which is dependent on the indicator's acid strength. An indicator's pH range is the range of pH values over which the indicator changes colors from its acid FORM to its base form.carbonic acid is the BUFFER present in blood..........

The pK's of the conjugate acid and base are related to each other by the EQUATION : Derivation of above equation : Let us TAKE an example of a weak acid which IONISES in aqueous : Now dissociation of weak base written as :Multiply ( i )  and  ( ii ) we get : TAKING negative log both side : Hence derived.

The product of CONCENTRATIONS of H+ and OH- ions in WATER at a particular temperature is known as IONIC product of water. The value of Kw increases with the increase of temperature, i.e., the concentration of H+ and OH- ions increases with increase in temperature.....EQUILIBRIUM constant K=[4H2]/4[H2O]....THANKU

1. Bronsted ACIDS can donate H⁺ easily but they may not be ABLE to donate electron like H₂SO₄ , HNO₃.Therefore , All Bronsted acids are not Lewis acids.Know more : Bronsted - Lowry Concept : According to this concept an acid is substance which can donate a proton H+ while base is substance which accepts proton.For example : HCl is acid as it loses proton.H₂O is base as it adds proton.Conjugates acid - base : The base which developed from an acid is called conjugates base. Like wise acid which is formed from base is called conjugates acid.2. CH₃⁻ is strongest conjugates base.Read more : In a gaseous REACTION A + B ⇄ C + 2 D, 3 mol of INERT gas is introduced into the vessel at constant PRESSURE. What  will be its effect on equilibrium? brainly.in/question/15893438​

There are many examples of chemical equilibrium all around you. ONE example is a bottle of fizzy cooldrink. In the bottle there is carbon dioxide (CO2) dissolved in the LIQUID. There is also CO2 gas in the space between the liquid and the cap.2. According to Lewis concept neutralization reaction is DONATION and acceptance of an electron pair to form a coordinate covalent bond in adduct. ... For example, formation of ammonium ION is a neutralization reaction between H+ (Lewis acid) and NH3 (Lewis base).Explanation:

a). Two APPLICATION of Buffer solution are as : 1. Buffer solution is used in medicines.2. BLOOD BUFFERS maintain the pH of blood.b). Equation of NH₃ to show Arrhenius base is follow : NH₃  +  H₂O  ⇒  NH₄⁺  +  OH⁻( Base )Know more : Buffer solution : It is defined as the solution which resists the change in hydrogen ion concentration on the ADDITION of small amount of acid or base.Read more : What is the effect of temperature on degree of dissociation ? In qualitative analysis, on what BASIS cations are grouped ? What is the effect of temperature on solubility product (K_sp) ?​brainly.in/question/15893251

,ark as brainliest and follow me plzExplanation: According to Bronsted-Lowry concept, acid is a substance which donates hydrogen ion and base is a substance which ACCEPTS hydrogen ion. ... Lewis BASES have lone pair of ELECTRONS. HENCE we can very easily identify the Lewis ACIDS and bases

1. The effect of temperature on degree of dissociation as degree of dissociation increases with increase in temperature.2. In QUALITATIVE analysis , CATIONS are grouped on the BASIS of their SOLUBILITY product ( K_sp ) .3. K_sp increases with increase in temperature because solubility increases.Know more : Solubility : It is defined as concentration of the SOLUTE in its saturated solution in solvent at given temperature.Solubility of solute in moles / litres = ( Solubility of solute in gram / litre ) / ( Mol. wt. of solute.

tion:For a weak electrolyte, the degree of dissociation is affected by temperature, concentration and the TYPE of solvent. For example, the degree of IONIZATION is HIGH at high temperature, low concentration and in polar solvent.

Explanation:CHILLED cold drinks bottles will have high extent of dissolved carbon dioxide. This is because the CO2 can dissolve more READILY in cold drinks bottles than the hot bottles. CO is dissolved at the high PRESSURE. In case of the hot bottles, there will be more expansion of the GAS and hence less dissolved CO.

n : What is meant by the statement 'Equilibrium is dynamic in  nature'?Answer:The statement 'Equilibrium is dynamic in  nature' mean at equilibrium the reaction doesn't stop rather it goes on. THEREFORE it is dynamic in nature. It SEEMS to stop because rate of FORWARD reaction is equal to rate of backward reaction.Read more : What is the effect of temperature on solubility of gases in  liquids?
