1. Interlining- To keep the different components or parts of apparel in a desired shape, a kind of fabric is used between two ply of fabric by sewing or fusing is called interlining.

2. Interfacing- Interfacing is a textile used on the unseen or wrong side of fabrics to make an area of garment more rigid. Interfacings are used to stiffen or to add body to the fabric.

3. Sleeve headers- Sleeve headers are designed to support the sleeve cap in coats and jackets (preventing dimpling).

Two methods usually used for markers making. 

1. Manual method 

2. Computerized method

1. Manual method- Traditional method of markers making Pattern maker make all the pattern pieces manually and after that fabrics are spread on cutting table and set up all the pattern pieces directly on to the marker paper. Then mark by chalk pencil or pen. It is suitable only for small production and has high labour cost. Method is time consuming.

2. Computerized marker making method: In the computerized marker paper directly placed on fabric layer. Then computer makes the marker by its programming techniques. It is suitable for large production. It is low time consuming. Require skilled operator and has high investment cost.

The fibre which is very strong and used to make ropes is nylon.

Answer: magnetic moment and colour

The geometries of both the complexes will be same because there coordination numbers are 6 and hence both will have octahedral geometry. The magnetic moment will change because in [Fe(H₂O)₆]²⁺ the ligand is H₂O which is a weak field ligand hence pairing won't take place in this molecule and hence will be high spin, high magnetic moment  while in [Fe(CN)₆]⁴⁻CN is the ligand which is strong field ligand and hence will cause pairing and therefore has low magnetic momment. Also, because of the difference in unpaired electrons the colour of the complex will also be different

Rutherford's Nuclear Model of the Atom

After α-particles scattering experiment, following conclusions were made by Rutherford as regard as atomic structure : 

(1)  Most of the mass (at least 99.95%) and all of the charge of an atom concentrated in a very small region is called atomic nucleus. 

(2)   Nucleus is positively charged and it's size is of the order of 10^-15 m » 1 Fermi. The nucleus occupies only about 10^-12 of the total volume of the atom or less. 

(3)   In an atom there is maximum empty space and the electrons revolve around the nucleus in the same way as the planets revolve around the sun.

The charge of an electron is equal to the inverse (opposite) of the elementary charge’s magnitude. The elementary charge’s value is approximately 1.602 x 10^-19  coulombs, so this means that the charge of an electron is -1.602 x 10^-19. That’s the quick version of an electron’s charge, but it would be beneficial to examine what an elementary charge is and how it affects the properties of electrons.

Charge to mass ratio of electron

In 1897 J. J. Thompson discovered the first "elementary particle", the electron, by measuring the ratio of its charge to mass in a manner similar to the experiment that we will perform. Given the mass and charge we expect to measure a value that is close to:

The charge to mass ratio of the electron is given by

e/m = 1.758820 × 1011 C/kg

Where,

m = mass of an electron in kg = 9.10938356 × 10-31 kilograms.

e = magnitude of the charge of an electron in coulombs = 1.602 x 10-19 coulombs.

π - bonding can occur by the overlapping of p-orbitals.

Correct option: (c) c and d are two electron clouds of one π - bond and it is formed by the side wise overlap between two p_z orbitals. 

Ion-exchange chromatography separates molecules based on their respective charged groups. Ion-exchange chromatography retains analyte molecules on the column based on coulombic (ionic) interactions. The ion exchange chromatography matrix consists of positively and negatively charged ions.

Answer is It is basic

When pressure is increased, rate of forward reaction increases. As a result, there will be an increase in the yield of product.

To remove the water content in the ammonia gas.

• Increase the concentration of reactants or anyone reactants. 
• Increase the temperature – Increases the rate of endothermic reactions. 
• Decrease the temperature- Increase the rate of exothermic reactions. Increase the pressure- Reaction takes place faster in the direction where the molecules are less. 
• Decrease the pressure- Reaction takes place faster in the direction where molecules are more. 
• Catalysts are added at the beginning of a chemical reaction.

a. In these reactions, the reactants change to products but the products cannot be changed back to reactants. 

b. Heat some Ammonium chloride in a boiling tube. 

c. No 

d. First two Reactions are irreversible reactions. Third Reaction is a reversible Reaction. 

e. Characteristics of Irreversible Reaction:- Reactants become products but products cannot be changed back to Reactants.

Characteristics of Reversible Reaction:- Reaction takes place in both directions.

Ammonia is lighter than air.

a. 2 

b. 4 

c. increases

a. Fe (CNS), (Ferric Thiocyanate) 

b. Yes, Red color increases 

c. 

d. At equilibrium both the reactants and products coexist. 

• The rates of forward and backward reactions become equal at equilibrium. 
• Chemical equilibrium is dynamic at the molecular level. 
• The system can attain equilibrium even when the concentration of the reactants and products are not equal. Once equilibrium has been attained, there will be no change in the concentration of reactants as well as that of products. 
• Chemical equilibrium is attained in closed system.

e. Even in equilibrium state reactants, molecules form products and products form reactants. Hence in minute level chemical equilibrium is kinetic energy. 

f. The concentration of reactants and products do not change a reversible reaction attain chemical equilibrium, 

g. A is the point at which the rates of both forward and backward reactions become equal. 

At equilibrium both the reactants and products coexist.

Forward reaction.

Rate of backward reaction increases.

The density of ammonia is lighter than air

1. N₂(g) + 3H₂(g) ⇌ 2NH₃ (g) 

Forward reaction: 

N₂ (g) + 3H₂ (g) → 2NH₃ (g) 

Backward reaction: 

2NH₃(g) → N₂ (g) + 3H₂(g) 

2. 2SO₂ (g)+ O₂ (g) ⇌ 2SO₃ (g) 

Forward reaction: 

2SO₂ (g)+ O₂ (g) → 2SO₃ (g) 

Backward reaction: 

2SO₃ (g) → 2SO₂ (g) + O₂ (g) 

3. H₂(g) + I₂(g) ⇌ 2HI (g) 

Forward reaction: 

H₂(g) + I₂(g) → 2HI (g)

Backward reaction: 

2HI (g) → H₂ (g) + I₂ (g)

Rate of forward reaction increases.

1. Water in the beaker lifts up in the flask which is filled with ammonia.

2. Ammonia dissolves abundantly in water. The pressure in the flask decreases with more ammonia dissolves in a water. So more quantity of water lifts up in the flask.

Ammonia dissolves abundantly in water. Ammonia gas is released when the tanker leaks, it dissolves in water and can minimize the spreading of gas into atmosphere.
