EXPLANATION:

• Periodic CLASSIFICATION of ELEMENTS is the method by which elements are GROUPED on the basis of their characteristics i.e. we KEEP the elements that are alike in one group and the rest of the elements in the other group.

The PERIODIC table, also known as the periodic table of ELEMENTS, is a tabular DISPLAY of the chemical elements, which are ARRANGED by atomic number, electron configuration, and recurring chemical properties. The structure of the table SHOWS periodic trends.

Answer:

NONE of these

Explanation:

because to FIND ELECTRONIC configuration and VALENCY all these were uses

In the FIELD of organic chemistry, a HOMOLOGOUS series is a sequence of compounds with the same functional group and similar CHEMICAL properties in which the members of the series can be branched or unbranched.[1] This can be the length of a carbon CHAIN,[1] for example in the straight-chained alkanes (paraffins), or it could be the number of MONOMERS in a homopolymer such as amylose

The condition produced by aerial OXIDATION of fats and OILS in food marked by unpleasant smell and taste is called Rancidity. For Example, Potato Chips when kept in air for a long time gives unpleasant smell and bad taste.

1.Rancidity can be prevented by ADDING anti-oxidants to foods containing fats and oils.

2. Rancidity can be prevented by packaging FAT and oil containing foods in Nitrogen gas.

3. Rancidity can be retarded by keeping food in Refrigerator.

4. Rancidity can be retarded by storing food in air-tight containers.

5. Rancidity can be retarded by storing foods away from light.

Answer:

Sulfuric acid (American English) or sulphuric acid (HISTORICAL spelling), also known as oil of vitriol, is a mineral acid COMPOSED of the elements sulfur, oxygen and hydrogen, with molecular formula H2SO4. It is a colorless, ODORLESS, and VISCOUS liquid that is SOLUBLE in water and is synthesized in reactions that are highly exothermic.[5]

CHEMICAL COMPOUND, any substance composed of identical molecules consisting of atoms of two or more chemical elements.

The Arrhenius definition of acid and base is limited to aqueous (that is, water) solutions. Although this is useful because water is a common solvent, it is limited to the relationship between the H+ ion and the OH− ion. What would be useful is a more general definition that would be more applicable to other chemical reactions and, importantly, independent of H2O.

In 1923, Danish chemist Johannes Brønsted and English chemist Thomas Lowry independently proposed NEW definitions for acids and bases, ONES that focus on proton transfer. A Brønsted-Lowry acid is any species that can donate a proton (H+) to ANOTHER molecule. A Brønsted-Lowry base is any species that can ACCEPT a proton from another molecule. In short, a Brønsted-Lowry acid is a proton donor (PD), while a Brønsted-Lowry base is a proton acceptor (PA).

It is easy to see that the Brønsted-Lowry definition covers the Arrhenius definition of acids and bases. CONSIDER the prototypical Arrhenius acid-base reaction:

H+(aq) + OH−(aq) → H2O(ℓ)

Answer:

The free energy RELEASED by ATP hydrolysis that may be coupled to an endergonic process via the FORMATION of a phosphorylated intermediate. As ATP begins to build up in a cell, metabolism slows down.

Explanation:

ATP is often called a high energy COMPOUND and its phosphoanhydride bonds are referred to as high-energy bonds. There is nothing SPECIAL about the bonds themselves. They are high-energy bonds in the sense that free energy is released when they are hydrolyzed, for the reasons given above.

The electron transport chain of the cellular RESPIRATION process produces maximum ATP.

Answer:

Olfactory indicator is a substance whose SMELL varies DEPENDING on whether it is mixed with an ACIDIC or basic solution. Olfactory INDICATORS can be used in the laboratory to TEST whether a solution is a base or an acid, a process called olfactory titration.

Explanation:

it may help you

Explanation:

Acids have long been recognized as a distinctive class of COMPOUNDS whose AQUEOUS SOLUTIONS exhibit the following properties:

A characteristic sour taste.

Changes the color of litmus from blue to red.

Reacts with certain metals to produce gaseous H2.

Reacts with bases to form a salt and water.

Acidic solutions have a pH less than 7, with lower pH values corresponding to increasing acidity. Common examples of acids include acetic acid (in VINEGAR), sulfuric acid (used in car batteries), and TARTARIC acid (used in baking).

There are three common definitions for acids

EXPLANATION:

This is the process to OBTAIN separate substances from this mixture.

1. Decant the mixture by removing the water FIRST. To the water, do distillation to obtain both SALT and water. (As the salt has dissolved in the water, this is necessary.)
2. The CAMPHOR can be handpicked. (As it has a volume and mass that is visible.)
3. Thus, you have salt, sand, camphor, water separately.

Answer:

O is exhausted and 3.20% P left over

Explanation:

4 P + 3 O2 → 2 P2O3

4 P + 5 O2 → 2 P2O5

Since you are told that the RESULT is equal moles of P2O3 and P2O5, these two equations can be ADDED together to form the overall reaction:

8 P + 8 O2 → 2 P2O3 + 2 P2O5

Then simplifying:

4 P + 4 O2 → P2O3 + P2O5

Take hypothetical samples of 100 grams each of P and O2:

(100 g P) / (30.97376 g P/mol) = 3.2285 mol P

(100 g O2) / (31.99886 g O2/mol) = 3.1251 mol O2

3.1251 moles of O2 would react completely with 3.1251 x (4/4) = 3.1251 moles of P, but there is more P present than that, so P is in excess and O2 is the LIMITING REACTANT (component), meaning that O2 is exhausted and P is left over.

(3.2285 mol P initially) - (3.1251 mol P reacted) = 0.1034 mol P left over

(0.1034 mol P) / (3.2285 mol P initially) = 0.0320 = 3.20% P left over

VARIATION of trend in non metals in groups:- Metallic CHARACTER decreases down the group since electronegativity decreases down the group as because the atomic size increases and Ionisation potential decreases. That's why electronegative character decreases so non metallic character decreases.

Variation of trend in non metals in periods:- Non metallic character increases ALONG the period because there is DECREASE in electronegativity along the period. This is the REASON why ionisation potential decreases so electropositive character increases.

⭐ DIELECTRIC constant can be defined as :-

• The ratio of the permittivity of a substance to the ratio of the permittivity of the free space.

It EXPRESSES the extent to which a material can hold electric flux in it.

⭐ Dielectric constant formula:-

K = E/E° where k = dielectric constant

E= permittivity of substance

And, E° = permittivity of free space.

⭐ Since, it is the ratio of TWO QUANTITIES so dielectric constant is a DIMENSION less quantity.
