ANSWER:

एक भौतिक परिवर्तन किसी पदार्थ के रूप में कोई भी परिवर्तन है जो उसके रासायनिक श्रृंगार को नहीं बदलता है। भौतिक परिवर्तनों के उदाहरण हैं एक छड़ी को तोड़ना या बर्फ को पिघलाना। एक रासायनिक परिवर्तन, या रासायनिक प्रतिक्रिया तब होती है जब किसी पदार्थ के परमाणुओं को पुनर्व्यवस्थित किया जाता है, और परमाणुओं के बीच के बंधन टूट जाते हैं या बनते हैं।

Answer:

Carbonic acid and carbonate SALTS

Carbonic acid (H2CO3) is formed in small amounts when its anhydride, carbon dioxide (CO2), dissolves in water.

CO2 + H2O ⇌ H2CO3

The predominant species are simply loosely HYDRATED CO2 molecules. Carbonic acid can be considered to be a diprotic acid from which two series of salts can be formed—namely, HYDROGEN carbonates, containing HCO3−, and carbonates, containing CO32−.

H2CO3 + H2O ⇌ H3O+ + HCO3−

HCO3− + H2O ⇌ H3O+ + CO32−

However, the acid-base behaviour of carbonic acid DEPENDS on the different rates of some of the reactions involved, as well as their dependence on the pH of the system. For example, at a pH of less than 8, the principal reactions and their relative speed are as follows:

CO2 + H2O ⇌ H2CO3 (slow)

H2CO3 + OH− ⇌ HCO3− + H2O (fast)

Above pH 10 the following reactions are important:

CO2 + OH− ⇌ HCO3− (slow)

HCO3− + OH− ⇌ CO32− + H2O (fast)

Between pH values of 8 and 10, all the above equilibrium reactions are significant.

Answer:

CA(OH)2

Explanation:

Ca(OH)2 i.e. Calcium HYDROXIDE is a base (ALKALI). All other (Sodium bicarbonate, Potassium Nitrate and Sodium Chloride) are Salts. NaHCO3 is a basic salt while KNO3 and NaCl are neutral salts.

a). We observed the CHANGE of STATE, change of temperature, chance of COLOUR and evolution of GAS.

ONE end of soap molecules LOVE water - they are hydrophilic. The other end of soap molecues hate water - they are hydrophobic. These DROPS of oil are suspended in the water. This is how soap cleans your HANDS - it CAUSES drops of grease and dirt to be pulled off your hands and suspended in water.

Answer:

When dilute hydrochloric acid is added to granulated zinc placed in a test tube, zinc metal is converted to zinc chloride and hydrogen gas is evolved in the REACTION. In the reaction we can SEE that a zinc chloride salt is FORMED and hydrogen gas is evolved. The evolved hydrogen gas is COLOURLESS and odourless.

OKKKKK PLZ MARK me as a BRAINLIEST

ANSWER:

Heat of formation, also called standard heat of formation, enthalpy of formation, or standard enthalpy of formation, the amount of heat absorbed or evolved when one mole of a compound is formed from its constituent elements, each substance being in its normal PHYSICAL state (gas, liquid, or solid). Usually the conditions at which the compound is formed are taken to be at a temperature of 25 °C (77 °F) and a pressure of 1 atmosphere, in which case the heat of formation can be called the standard heat of formation. The heat of formation of an element is arbitrarily assigned a value of zero. By using Hess’s law of heat summation, one can calculate the heat absorbed or evolved in any CHEMICAL reaction by summing the known heats of formation or combustion for the steps in that reaction.

Explanation:

Explanation: Answer: Here, non-metal is hydrogen which is evolved as GAS. It is displaced by the metal zinc. In the given equation - ZN(s) + 2Hcl(aq)-----> Zncl2(aq) + H2(g), Zinc (Zn) is a REDUCTANT metal that displaces hydrogen (H2) from aqueous solution of Hydrochloric acid (HCl).

Answer:

c and d are correct

Explanation:

(c) the COVALENT compounds are formed by sharing of electrons in the atom hence they have SIMILAR ELECTRONEGATIVITY which results in weak BONDING so they are present in all states.

(d) since covalent compounds of formed by combination of metal and non metal they have only molecules but no ions they are incapable of conducting electricity .

ANSWER:

the PROCESS in which green plants and some other ORGANISMS use sunlight to synthesize nutrients from carbon dioxide and WATER

Answer:

i) :- he can use it as an indicator.

ii) :- as lemon juice is an acid, then it will turn dark MAGENTA COLOUR because it reacts with the indicator.

iii) soap water is a base so when it is MIXED with china rose water, it changes to green colour as it reacts with it.

iv) indicators are used to see whether a SUBSTANCE is acid or liquid. it has different COLOURS when mixing with acid and base. there are different indicators which also change their colour once they come in reaction with each other.

Answer:

if the ELECTRONEGATIVITY difference b/w TWO bounded ATOM is greater than 1.7 than IONIC bond formed but if its is less than 1.7 than covelant bond from as H20 has Electronegativity difference less than 1.7 so it has covalent bond and Mgo has ionic bond.

Answer:

After IDENTIFICATION of KETONE, to identify benzophenone you need to FIND the range of melting point using melting point APPARATUS which you should get in range of 48.3 ∘C48.3 ∘C to 50.6 ∘C50.6 ∘C.

Then you can find IR of unknown(benzophenone).
