The sulfur ION has an extra shell than an oxygen ion, so the ATOMIC size of sulfur should be GREATER than oxygen. THEREFORE, the IONIZATION energy of an oxygen ion should be more than a sulfur ion because the electrons in oxygen are closer to the nucleus when compared to sulfur.

Answer: The mixture of sulphur and IRON filling is CONSIDERED to be heterogeneous mixture in NATURE because the PARTICLES of each don't mix with each other ,and they are not evenly distributed and they are EASILY separated.

Hope this will help you.

ANSWER:

hydrochloric acid

The hydrochloric acid in the gastric juice BREAKS down the FOOD and the DIGESTIVE enzymes split up the proteins. The ACIDIC gastric juice also kills bacteria. The mucus covers the stomach wall with a protective coating.

Answer:

Irreversible chemical reactions can occur in only one direction. The reactants can change to the products, but the products cannot change BACK to the reactants. Reversible chemical reactions can occur in both directions. The reactants can change to the products, and the products can also change back to the reactants.

EXAMPLE of irrevisible reactions is Combustion involves burning an organic compound—such as a hydrocarbon—​and oxygen to produce carbon dioxide and WATER. Because water and carbon dioxide are stable, they do not REACT with each other to form the reactants.

example of a reversible REACTION is the reaction of hydrogen gas and iodine vapor to from hydrogen iodide.

Explanation:

Merits are as FOLLOWS:-

1. There was a regular gradation in physical and chemical properties of elements.

2. The group number of an element indicates highest oxidation state that it can attain.

3. There were many vacant spaces in MENDELEEV's periodic table for the elements to be discovered. He named them Eka-Boron, Eka-Aluminium and Eka-silicone He also predicted the properties of these undiscovered elements including atomic MASSES. These elements were discovered as Sc ,Ga and Ge with same features as he predicted.

4. Mendeleev’s arrangement helped to correct atomic masses of a number of elements.

Demerits are as follows:-

1. The elements, if arranged according to their atomic weights show an evident periodicity of properties.

2. Elements which are similar as regards their chemical properties have atomic weights which are either nearly the same value or which increase regularly.

3. The arrangement of the elements or of groups of elements in the order of their atomic weights, corresponds with their so called VALENCIES.

ANSWER:

An element is composed of same TYPE of atoms.

it is a pure substance.

total of 118 elements are present.

based on PROPERTIES these are divided into metals , NON metals, metalloids.

Answer:

7g

Explanation:

AgNO3+NaCl→AGCL+NaNO3

ForAgNO3,

V=50ml

V/W%=16.9%

W/50=16.9/100

WAgNO3=8.45g

nAgNO3=WAgNO3/MAgNO3

=0.05

ForNaCl,

V=50ml

W/V%=5.8%WNaCl=2.9g

nNaCl=WNaCl/MNaCl

=0.05

According to REACTION AgCl(ppt) = 0.05 moles ×

Molar MASS of AgCl = 0.05 × 142.8 = 7.14g ≈ 7g

Answer:

The Decreasing ORDER of dipole moment is this way.

Nitrobenzene, phenol,phenylamine,methylbenzene.

Explanation:

The nitro group OBVIOUSLY Attracts electrons and results in HIGHER dipole moment. Phenol has higher ELECTRONEGATIVE atom oxygen as compared to Nitrogen in Phenylamine.So, phenol has higher dipole moment. Methyl benzene has a least dipole because, the alkyl group readily donates

1. A FORCE acting on an object causes the object to change its SHAPE or size, to start moving, to stop moving, to accelerate or decelerate. When there’s the INTERACTION between two objects they exert a force on each other, these exerted forces are equal in size but opposite in direction. When an object has SEVERAL forces acting on it, the effects of force is same as one force acting on the object in a certain direction and this overall force is called the ‘resultant force’. The resultant force is essential to change the velocity of an object.

• If the resultant force is zero the forces on the object are balanced.
• If the resultant force acting on the object is ‘zero’ then: the object will remain stationary. In such a case the object will move at a steady speed in a straight line.
• If the resultant force acting on the object isn’t zero then: the object will either accelerate or decelerate.

2. Non-contact forces – allow remote PARTS of the environment to affect an object: Magnetic force. Electric force.

Answer:

The Hall–Héroult process is the major INDUSTRIAL process for smelting ALUMINIUM. It involves dissolving aluminium oxide (ALUMINA) (obtained most often from bauxite, aluminium's chief ore, through the Bayer process) in molten cryolite, and electrolysing the molten salt BATH, TYPICALLY in a purpose-built cell.

Answer:

Ethyl CHLORIDE is converted into Propane Nitrile FIRST and then by HYDROLYSIS, it is converted into PROPANOIC Acid.

Explanation:

Ethyl Chloride having the chemical composition of or is having the weight 64.5 grams is converted into Propane Nitrile at the first stage and by reacting it with Potassium Cyanide, KCN.

The reaction is:

The obtained KCl is a by-product and is extracted.

Then Propane Nitrile, is converted into Propanoic acid by the Hydrolysis process.

The reaction is:

CH3CH2OH+KCN →CH3-CH2-c=-N

Ethanol CH3CH2-C(TRIPLE bond with)N which is propanenitrile

Answer:

Explanation:

1 gram of CaCO3 INDICATES 0.01 moles of it.

                 CaCO3  ------------------> CAO  +  CO2

1mole of CaCO3 gives 1mole of CO2 on heating.

so, 0.01 moles of CaCO3 gives 0.01moles of CO2.

1mole of CO2 means 22.4litres of it,

thus 0.01 moles of CO2 indicates 0.224litres = 224millilitres

Answer:

f steam is passed over RED HOT iron, it is converted into its magnetic oxide and HYDROGEN gas. If on the other hand, hydrogen is passed over heated magnetic oxide, it will change BACK to iron and steam. This reaction can be made to proceed in both directions, so it is called reversible reaction.

Answer:

Second EQUATION of Motion - Derivation s = ut + 1/2 ^2 Derivation × We know that Velocity = / Velocity × Time = Displacement Displacement = Velocity × Time If Velocity is not constant (i.e. Velocity keeps on increasing or decreasing) We can also take AVERAGE Velocity in place of Velocity So ours = ut + 1/2 AT2. is the second equation of motion. It is also CALLED position-time relation. Using this formula we can CALCULATE the displacement when the values for time, acceleration and initial velocity are known. s - displacement

Colloid solution:-

A mixture in which one SUBSTANCE is divided into MINUTE PARTICLES (called colloidal particles) and dispersed throughout a second substance. ... The mixture is also called a colloidal solution, colloidal system, or colloidal dispersion. The three forms in which all matter exists are solid, liquid or gas.

Suspension:-

A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase SOMETIME after their introduction. ... We apply the word 'suspension' when particles are big enough to eventually settle. If the particles are too small to EVER settle, they are said to form a colloid.
