Answer:

We should wear COTTON clothes in SUMMER because during summers we tend to sweat a lot and cotton fabric absorbs this sweat and helps the BODY to cool down. Cotton clothes provide better air circulation LEADING to more absorption of sweat and thus gives a cooling effect to us

KC = [D][C] / [A][B]

Kc is the ratio of MOLAR CONCENTRATION of PRODUCTS to the molar concentration of the reactants where, each term is raised to the stoichiometric coefficient as it's power

ELECTRONS are NEGATIVELY CHARGED IONS

Answer:

right

Explanation:

as per electron CAPACITY of shell K , L , M

first contain 2 elements

second contain 8 elements

third shell should contain 18 element but contain only 8 element DUE law of electron of octet

(none) Bananas are another FRUIT that contains natural digestive enzymes.

They contain amylases and glucosidases, two groups of enzymes that break down complex carbs like starch into smaller and more easily absorbed sugars (17Trusted Source).

Like mangoes, these enzymes break down starch into sugars as bananas start to ripen. That’s why ripe yellow bananas are much sweeter than unripe green bananas (18, 19).

On top of their ENZYME content, bananas are a great source of dietary fiber, which may aid digestive health. A medium banana (118 GRAMS) provides 3.1 grams of fiber (20).

Answer:

The cause of periodicity in properties is the repetition of SIMILAR outer electronic configuration after certain REGULAR intervals. Forexample, all the ELEMENTS of GROUP LA i.e., ALKALI metals, have similar outer electronic configuration as ns1.

Answer:

Solids are broadly CLASSIFIED into two types crystalline solids and amorphous solids. A crystalline solid is a substance whose CONSTITUENT PARTICLES possess regular orderly ARRANGEMENT e.g. Sodium chloride, sucrose, diamond etc.

ANSWER:

PHENOL is the FINAL PRODUCT.

Answer:Oxalic acid has the FORMULA C2H2O4 (HOOC-COOH) so it is diprotic . Therefore, the equivalent weight of crystalline oxalic acid = 63. If you prepare 1.0 N solution of oxalic acid, you need to dissolve 6.30 g of it in ENOUGH distilled water to have a solution with total volume of 100 mL. Place the oxalic acid solution in a flask with few drops of an indicator (ph.ph can be used).

Pour the volume you select for 0.1 N solution (it is the same as 0.1 M solution) of NaOH in the buret but since it is still not standardized, the concentration will be considered as unknown.

Add NaOH solution titrant to the analyte until the end point is reached.

Apply the equation N x V (oxalic acid) = N' x V' (NaOH), where N,V, and V' are known. Find out N' which will not be far from 0.1 (probably 0.13 to 0.97 ).

Use the NaOH normality you get for CITRIC acid estimation by titration.

Explanation:

Answer:

HCL- MOLE WEIGHT 36.5

basicity-1.

equation weight-36.5

1mole=1000ml

to find molal.

molality=mole of HCL/mass of solvent×1000

ans in mol kg^-1 (or m)

The moisture present in the atmosphere is CALLED HUMIDITY. A DRY atmosphere can hold more water molecules than a humid atmosphere. Hence, the rate of EVAPORATION of aqueous solution decreases with the increase of humidity and vice VERSA.

ANSWER:

It GENERALLY DEFINES the ability to completely dissolve one LIQUID to the other, with formation of distinct layers. And, the process of separation of miscible liquids is called as distillation. The liquids which completely dissolves in other ones are known as miscible liquids 

Explanation:

PLZZ MARK AS BRAINLIST.

ANSWER:

The colour obtained by D-Block i.e Transition elements is due to the presence of unpaired electrons which can let d-d transition OCCUR.

However If there are no electrons or if the d-orbital is completely filled then d-d transition cannot occur and hence no colour can be obtained.

In this CASE, The electronic CONFIGURATION of Scandium in ground state is [Ar] 3d1 4s2

When it's losing 3 electrons from its valence shell to form +3 cation, it's electronic configuration becomes

[Ar] 3d0 4s0 which implies that it has no electrons in d-orbital to let d-d transition occur.

and hence, SC3+ is colourless..

The electronic configuration of  ELEMENTS A IS  2,8,3

means ATOMIC no is = 13 which is AL (Aluminium )

element B has electronic configuration 2,8,7  

means atomic no is  = 17 , which is of chlorine  .

The COMPOUND formed is Al Cl₃

nature of the compound will be covalent    .

Answer:

The production of IRON USING hydrogen as a reducing agent is an alternative to CONVENTIONAL iron-and steel-making processes, with an associated decrease in CO 2 emissions. Hydrogen PLASMA smelting reduction (HPSR) of iron ore is the process of using hydrogen in a plasma STATE to reduce iron oxides
