In order to calculate the % composition of KClO3 , we will calculate the MOLAR mass of the MOLECULE with the HELP of molar masses of K, Cl and O.

=> Molar mass of KClO3
=> [39 + 35.5 + 3×16] gm
=> 122.5 gm
-____________________

So

=> mass % of K = (39/122.5)×100
= 31.84 %
____________

=> mass % of Cl = (35.5/122.5)×100
= 28.98 %
____________

=> mass % of O3 = (48/122.5)×100
= 39.18 %
___________

Hii There!!!


Since, Density of a gas = Mass/ VOLUME
=) 3.2gm/280 ml


Molecular mass = molar vol. × density

Since, molar volume at N.T.P = 22.4L =) 22.4×1000ml

So, molecular mass= 22.4 × 1000× 3.2/280 = 256

Now ,Molecular FORMULA = n × Empirical formula

=) n = molecular mass / empirical mass

=) n = 256/32 =8

Hence, molecular formula of sulphur VAPOUR = 8 × S

=) S8

Paramagnetism is a property of certain materials by which they are weakly attracted in the magnetic field. The presence of unpaired electrons in the materials forms an internal magnetic field by alignment of electrons in ACCORDANCE with the externally applied magnetic field.

The magnitude of paramagnetism is determined by determining its magnetic moment (∪, greek letter-mu), which in TURN is determined by its NUMBER of unpaired electrons present in the ion of the MATERIAL. Its unit is BM.

Magnetic moment, ∪ = √n(n+2)

Since species are not mentioned here in the question, let us find out which among Cu2+ and Fe2+ has largest paramagnetic moment.

Cu2+ ---> [Ar]18 3d9 ; unpaired electrons: 1

Magnetic moment = √1(1+2) = √3 = 1.73 BM

Fe2+ ---> [Ar]18 3d6 ; unpaired electrons : 4

Magnetic moment = √4(4+2) = √24 = 4.89 BM

Here, as Fe2+> Cu2+ in magnetic moment, it has the

t of the TWO species.

The composition of the Lok Sabha ACTUALLY STUDIES the current composition and includes different solution for evaluating results.

Gsy Lusaac law is also practical in our day to day life too:
1) FIRING a BULLET. When gunpowder burns, it CREATES a significant amount of superheated gas. The high pressure of the HOT gas behind the bullet forces it out of the barrel of the gun.
2) • Heating a closed aerosol can. The increased pressure MAY cause the container to explode. You don't toss an "empty" can of hairspray into afire.

When a solute (LIKE sugar or salt) is added to a definite volume of water, volume of water doesn't increase, only mass of liquid increases. Hence it proves that solute MOLECULES have entered gaps present between water molecules. If there would have been no gaps EITHER solute would not DISSOLVE in water or it would shift water molecules away thereby increasing volume of liquid.

Self indicator is actually a chemical SUBSTANCE which can mark the end point of a titration or any other reaction along with self-participation in the reaction. For example, acidified Potassium dichromate paper turns from orange to green in presence of Sulphur dioxide.
external indicator:
Indicator which never takes part in the original chemical reaction but after completion of reaction it also changes the color of solution to indicate the endpoint. External indicators is not recommended as it leads to LOSS of some volume of the reaction MIXTURE.
Redox indicator:
Redox Indicators are an indicators that undergoes a definite color change at a specific electrode potential,and shows a reversible color change between oxidized and reduced forms. Loba chemie OFFERS wide range of redox indicators which are use as a Indicator in redox titrations.

Save Fuel for BETTER Environment and Health
_____________________________________________________________

Fuel refers to substances used as sources of energy in vehicles, machines and factories. Petroleum fluids and coal are the main sources of fuel. Petroleum fuels are mainly used in transport and in coal-fired power plants. There are also many types of petroleum fuels such as petrol or gasoline, diesel, kerosene or kerosene oil, ATF, naphtha, natural gas, LPG etc. All these petroleum PRODUCTS are extracted from the separation of mineral oil or crude oil.

Millions of years ago, mineral oil was formed from being buried beneath the rocks of dead vegetation and organisms such as algae and plankton etc. Therefore it is also called fossil fuel. Because they can not be reproduced, they are also called non-renewable or ineffable energy sources.Due to the quick and easy fuel, petroleum fuel has been used extensively throughout the world for several decades. Only limited amount of petroleum fuel is AVAILABLE, so human society has the responsibility to protect it. If we currently conserve mineral oil, then it will be available to the next generation. By conserving fuel, we reduce the environment even less.

Many institutions of the world have come forward to save fuel and important efforts are being made in this direction. We can also play a commendable role in conservation of fuel by following the following habits and remedies in our DAILY life:

1. Use bus transport, such as public transport.
2. Do not leave the engine running the engine, like if the traffic signal is red, turn off the engine.
3. Do not keep the gas stove in the house if you do not use it.
4. Take care of the engine from time to time.
5. Keep appropriate pressure in the tire of the trains.
6. Use the car pool if it is in the office.
7. Do not press excelster in vain but RATHER drive in an economical manner.
8. Nowadays, electric and hybrid vehicles are also available.
9. Use cycles for short distance and if possible, walk on foot.
10. Do not have to heat the food repeatedly and so eat together.
11. Adopt power saving methods so that protection of coal is possible.

The Government of India will also implement BS vi Bharat Stage 6 Petrol and Diesel, by 2020, with the aim of doing pollution work, which will result in a lot of pollution emitted by the vehicles.

The poem is about the JOY that a poor women GETS by writing her name on the mud.

Although she cannot write it CORRECTLY SPELLED, although she is not literate and although she is not good looking, still the joy of writing the first word is tremendous and shows on her FACE.

1 mole h2so4 has 2 moles of h+ IONS. so in (100/1000)× 0.001 moles u can easily find using UNITARY METHOD

Pressure and temperature are directly proportional - double the temperature, and pressure doubles.

15 DEGREES C = 288 K

Since pressure NEEDS to be doubled, temperature needs to be doubled as well:

288 K * 2 = 576 K (or 303 degrees C).

This shows that matter has intermolecular SPACES PRESENT in it. The diver seperates the water particles through its intermolecular SPACE to go FORWARD.

Corrosion:- is nothing but it is a chemical reaction (most LIKELY a oxidation process) in which wearing of METAL takes place . Here the metal can be anything IRON, copper etc . Rusting :-This is a part of corrosion in which Iron reacts with water or moist AIR to form iron oxides and therebycorrosion takes place .

Metals are dense, shiny, good conductors of HEAT and electricity, and EASILY LOSE electrons in CHEMICAL reactions. Nonmetals are not dense, dull, do not conduct heat and electricity, and tend to gain electrons. Metalloids are elements that have properties of both metals and nonmetals.

The acidic, basic or neutral character of any solution can be expressed by expressing its H+ ion concentration. A Danish biochemist Peter Sorensen suggested a method of expressing the concentration of H+ ions in terms of pH. In Danish language, pH stands for protenz de HYDROGEN which means power of H+ ions. pH of a solution is given by

pH = -log [H+] = log 1[H+]

where [H+] = concentration of hydrogen ions in solution.

To report the pH, a SFOR an acidic solution, pH is less than seven.

For a basic/alkaline solution, pH is greater than seven.

For a neutral solution, pH is equal to seven.

The pH of a solution is measured accurately using an apparatus known as pH meter. An approximate value of pH can be obtained by using universal indicator/pH paper.

Indicators: are the SUBSTANCES which change the COLOUR at a certain pH. Some common examples of indicators are litmus, phenolphthalein and methyl orange. Out of these, litmus is a NATURAL indicator while phenolphthalein and methyl orange are synthetic indicators. cale from 0 to 14 was devised.

Because the PARTICLES of GAS are countinuesly on MOVING.
