ANSWER:

hey!

The bond formed between two atoms by sharing a pair of electrons, provided entirely by one of the combining atoms but shared by both is called a coordinate bond. It is represented by an ARROW STARTING from the donor atoms and ending in the ACCEPTOR atom.

Corrosion: PROCESS by which the layers of undesirable COMPOUNDS are formed on the surface of a metal on its exposure to atmospheric conditions are called corrosion.

ELECTROCHEMICAL theory of corrosion:

It is widely accepted electrochemical reaction. A number of galvanic cells are formed in impure IRON.

Answer:

One of the most common iron oxides is iron (III) oxide, known as RUST. The chemical formula forrust is Fe2O3. Rust is formed when iron REACTS with oxygen in moist air. The following chemical equation REPRESENTS the reaction: 4Fe + 3O2 → 2Fe2O3.

ANSWER:

Explanation:

ALDOL CONDENSATION can be DEFINED as an organic reaction in which enolate ion reacts with a carbonyl compound to form β-hydroxy ketone or β-hydroxy aldehyde, followed by dehydration to give a conjugated enone. Aldol Condensation plays a vital ROLE in organic synthesis, creating a path to form carbon-carbon bonds.

Explanation:

Imagine that you are given two sets of wooden planks and asked to make something out of them - anything you want. You get out your glue, saw, NAILS, and hammer and start building. Eventually, you end with something like this:

While your final product MIGHT look unusual, the process you used to make it is similar to what happens in an addition reaction.

A addition reaction occurs when atoms are added to a compound containing a double or triple bond. Think of an addition reaction as two DIFFERENT REACTANTS combined in a large SINGLE product that contains all the elements present in the individual reactants.

Let's take a look at those wooden planks again and pretend that they're molecules. In an addition reaction, molecule A combines with molecule B to make a single product, just like your odd-shaped, yet beautiful, work of art. As a single product, it contains the exact same type, color, and style of wood originally used.

This is a very important point, as the product of addition reactions contains all the atoms and elements originally present in the reactants being combined. Now, let's go over some basic rules for performing addition reactions.

Answer: it is because in the FIRST CASE the sum of locants is 7 while in second place the sum of locants is 8 so LESS locant sum is preferred

ANSWER:

it is an colidal SOLUTION

We know that, ΔCp = ΣnCp PRODUCTS - ΣnCp REACTANTS = [(1x 75.312) - ( 1x 38.83 - 1/2 x 29.16 )] = 51.06 J/K/mol = 0.051 kJ/K

Further , we know from Kirchoff's law,

ΔH(at FINAL temperature) –ΔH(at INITIAL temperature) =[ (Cp(final) -Cp (initial) (T(final ) -T( initial)] = ΔCp (Tf -Ti )

Or, ΔH ( 373K) - ΔH (298K) = ΔCp (Tf -Ti )

Or, ΔH ( 373K)- (-285.76 kJ/K) = 0.051kJ/K x ( 373K-298K) = 3.825 kJ

or, ΔH ( 373K) = 3.825 - 285.76 = -281.93 kJ

Hence, ΔH ( at 373K) = -281.93 kJ

ANSWER:

Industrial production of ammonia gas is carried out by Habers process. In this method, dihydrogen and dinitrogen gases are mixed in 3:1 proportion by volume and then passed over iron CATALYST at 200-300 bars of pressure. A temperature of about 773 K is MAINTAINED during this reaction. Substances like Al_2O_3, K_2OAl

O are added to increase the efficiency of the catalyst. Hence, they are called propmoters. By cooling the reaction mixture at a temperature lower than 273 K, ammonia can be separated from the unreacted N_2N

Answer:

4 atoms

EXPLANATION:

In a FCC lattice there are 8 atoms at eight CORNERS and 6 at face centers,

Now each corner contributes to eight cells so per unit cell CONTRIBUTION is 1/8 times 8=1

1/8 ×8=1 atom.

Now similarly each face center contributes to two unit cells so contribution per unit cell by six face centers is equal to 1/2 times6=3

1/2 ×6=3 atoms.

Hence total no. of atoms per unit cell of FCC lattice is (1+3) =4 atoms.

Explanation:

A mole corresponds to the mass of a substance that contains 6.023 x 1023 particles of the substance. The mole is the SI UNIT for the amount of a substance. Its symbol is mol. By definition: 1 mol of carbon-12 has a mass of 12 grams and contains 6.022140857 x 1023 of carbon atoms (to 10 significant FIGURES).

Molar mass of urea = 60g

No.of moles = GIVEN mass/molar mass

= 5.6/60 = 0.09 moles.

No.of molecules = Avogadro no.of moles

= 6.022×10²³×0.09 = 0.56×10²³ molecules are present.

5%solution

SOLUTE - 5gram

solvent - 95 gram (H2O)

Use Formula

Pa° -Ps/Pa° = XB

Pa° - 760

PS - 745

Xb = MOLE fraction of Solute

15/760 = nB/nA + nB

nA /nB = 50

nA = 95/18

nB = 5/M

M = 47.5 gram
