It helps to form slag fesio3 to remove iron present as impurity

You cannot devise a relationship between two as in case of adsorption they can either be vanderwaal forces or chemical bonds.....although they differ for different materials

Lewis Structure of NO3- (Nitrite ion) Lewis structure of NO3- ion is drawn step by step in this tutorial. Total valence electrons of nitrogen and oxygen atoms and negative charge are considered to draw the NO3- lewis structure.

Excuse me Ma'am I wanted the derivation.

The Nernst equation provides a relation between the cell potential of an electrochemical cell, the standard cell potential, temperature, and the reaction quotient. Even under non-standard conditions, the cell potentials of electrochemical cells can be determined with the help of the Nernst equation.

The Nernst equation is often used to calculate the cell potential of an electrochemical cell at any given temperature, pressure, and reactant concentration. The equation was introduced by a German chemist Walther Hermann Nernst.

Derivation of mirror formula for a concave mirror

If temperature is increased the ions vibrate with more amplitude about their mean position and the number of collisions electrons make increase and impedes the flow of electrons. So, the conductivity decreases as the temperature is increased. In metals no of electrons and its charge remains same but mobility reduces.

Voids literally mean gaps between the constituent particles. Voids in solid states mean the vacant space between the constituent particles in a closed packed structure. ... These empty spaces are called voids and in the case of hexagonal packing, these voids are in triangular shapes and are known as the triangular voids. In cubic closed packing, there are two types of voids: Tetrahedral void - A void in a lattice which is surrounded by four spheres is called a tetrahedral void. The four spheres surrounding the void are arranged on the corners of a regular tetrahedron.

A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase. A solution consists of a solute and a solvent. For example, in a saline solution, salt is the solute dissolved in water as the solvent. 

A solution is a homogeneous mixture of one or more solutes dissolved in a solvent.

• solvent: the substance in which a solute dissolves to produce a homogeneous mixture
• solute: the substance that dissolves in a solvent to produce a homogeneous mixture

When an unsymmetrical reagent is treated with unsymmetrical alkene in presence of peroxide,then addition takes place against the Markownikoff's rule i.e. negative part of reagent adds to that carbon ot carbon-carbon double bond which carries more number of hydrogen atoms. This is known as peroxide effect. 

I'm in 12 class and I'm making a plan that how to complete my syllabus before August so that I can also do plenty of questions for neet so that's why I was asking if I decide to come 4 chapters in 20 then will I be able to complete my syllabus and will be ready to do questions of the chapter as much as I can

If you had concentrated in the class, you'll be able to catch up something like minimum 2 chapters.Maximum number of chapters which you will cover up depends on your dedication to your study hours.Eg:If you study for 2-3 hrs with maximum concentration, you'll pick up everything easily.But a study duration of 6-7 hrs with distractions is an utter waste of time(That doesn't mean that you shouldn't study for 6-7 hrs....If you study for 6 hrs daily with complete concentration,it won't feel tough).Also,it depends on the length of the chapter.If you are preparing for an upcoming exam,I think you should finish up all the small chapters so that you can attempt questions from those chapters at least...So I think that 4 chapters can be easily completed that too, within a duration of 20 days,if done with full concentration(PS: These are applicable if you had attended the classes of those chapters only,else,you should dedicate extra time for listening to the class online or something like that....)

The monomeric unit of orlon polymer is Acrylonitrile. Orlon is also known as Polyacrylonitrile (PAN).

Maximum amount of solute dissoved in solvent in a liquid

Solublity of a solid in a liquid is given amount of solid that can be dissolved in given amount of solvent generally to form 100g of solution at given temp.

Solubility is a physical property of a solution. It can be defined as the measure of maximum amount of solute that can be dissolved in a quantified amount of solvent.

This property of solution depends upon the factors like:

• The nature of soluteand solvent and the interaction between them :The stronger the attractions between solute and solvent molecules, the greater will be the solubility.

• Molecular size of solute :Larger molecules are more difficult to dissolve in solvents whereas the smaller molecules dissolve easily and are more soluble in solvents.

• Polarity :Polar solvents (having bonds with different electro negativities) like Water, ethanol, formaldehyde dissolve polar solutes whereas nonpolar solvents (having bonds with similar electro negativities) like pyridine, toluene, and hexane dissolve nonpolar solutes.

• Temperature : Rise in temperature increases the solubility.

• Pressure : Rise in pressure increases the solubility.

For volatile liquids the pressure of a given gas is directly proportional to mole fraction

Raoult’s law

• Raoult’s law establishes a quantitative relationship between the partial vapour pressure and mole fraction of a solution.
• This law is only for liquid-liquid solution.
• The law states that for a solution of volatile liquids, the partial vapour pressure (p) of each component in the solution is directly proportional to its mole fraction (x).
• Mathematically, p ∝ x

            Or p = p ⁰x 

Where p⁰ is the vapour pressure of pure component at the same temperature.

Ethyl amine is C2H5NH2.
Here,the ethyl group has a strong +I effect.It increases the electron density over Nitrogen atom.As a result,the unshared electron pair becomes more easily available for sharing.
This leads to increase in basicity.
And ammonia has no such +I groups, which could increase the basicity.
So,it is less basic than ethyl amine.

Ethylamine is more basic than ammonia as in ethylamine the ethyl group is electron donating group which increases the electron density at amine group and hence it can easly donate electron and hence is more basic then ammonia which have less electron density then ethylamine 

The sum of the lengths of the sides is the perimeter of any polygon. In the case of a triangle,

Perimeter = Sum of the three sides.
