They have special organs as in fish GILLS which filter OXYGEN and WATER and MAKE USE of both

There are many elements but exact FRONT of FLUORINE is neon.
after that Na, MG, Al, Si, P, CL

25g/0.5mol = 50g/MOL 

There are 4 mol of CHLORINES 

50g/mol* 4mol = 200G

Dry ice is solidified CARBON dioxide and it is called so because Carbon dioxide has no liquid state. Dry ice directly sublimates to gaseous Carbon dioxide.

As FAR as storage and transportation is concerned, it is conventionally packed in thick STYROFOAM BOXES that are insulating and prevent human contact as dry ice can CAUSE cold burns on contact.

As PER your QUESTION it should be APPROXIMATELY 8

Calculate the volume of chlorine GAS LIBERATED at the ELECTRODE at NTP. ... Solution: The chemical reaction occurring during ELECTROLYSIS is

The term "band gap" refers to the ENERGY difference between the TOP of the valence band and the bottom of the conduction band. ... Electrons can gain enough energyto JUMP to the conduction band by absorbing EITHER a phonon (heat) or a photon (LIGHT).

A SOLID AB has ROCK salt structure. If RADIUS of CATION A+ is 120 pm, what is the MINIMUM value of radius of B- anion?

Answer:

here is the answer

Explanation:

Amphoteric oxides EXHIBIT both basic as well as ACIDIC properties. When they react with an acid, they produce salt and WATER, showing basic properties.

It ACTIVATES many mechanisms SIMULTANEOUSLY, dehydration ,exosmosis ,in some CASE plasmolysis as more salt concentration WATER GET imbalanced

Hypophosphorus ACID, H3PO2, +1. Phosphorus acid, H3PO ... The structures of OXOACIDS of phosphorus are SYSTEMATICALLY GIVEN AHEAD:

It VARIES ACCORDING to the REACTANTS we TAKE

H 2 O is neutral nucleophile and 3 ∘ ALKYL halide with neutral nucleophile undergoes elimination as WELL as substitution.
Thus (CH3)2-COH-CH2-CH3 is the RIGHT answer

Yes, because it is HYGROSCOPIC in nature and readily dissolve in water to form IONS.

Pure METALS may be too soft to HOLD up to REGULAR use, but alloying them makes them tougher. ... Jewelry MANUFACTURERS alloy pure gold with silver, copper or zinc to improve the metal's durability and rigidity. The gold contributes its color and resistance to corrosion; the other metals contribute their strength

When the NADP(NICOTINAMIDE ADENINE DINUCLEOTIDE phosphate) accepts an hydrogen ion then it become NADPH OR Reduced Nicotinamide dinucleotide phosphate

It is TYPICAL for normal-phase chromatography on silica that the mobile phase is 100% organic; no water is used. The TERM reversed-phase describes the chromatography mode that is just the opposite of normal phase, namely the use of a polar mobile phase and a non-polar [HYDROPHOBIC] STATIONARY phase.

In fibrous protein polypeptide chains are HELD together by triple and DOUBLE hydrogen bonds

Free rotation (hindered rotation, restricted rotation)
In a stereochemical context the rotation about a bond is called 'free' when the rotational barrier is so low that different conformations are not perceptible as different CHEMICAL species on the TIME scale of the experiment. The INHIBITION of rotation of groups about a bond due to the presence of a SUFFICIENTLY LARGE rotational barrier to make the phenomenon observable on the time scale of the experiment is termed hindered rotation or restricted rotation.

Because the LIQUID FUEL START FLOATING on WATER

The POLLUTANT that was the reason for the Bhopal GAS TRAGEDY is 'Methyl ISOCYANATE' [CH₃-OCN]

HOPE it helps!!

1 mole = 6.023 x 10^23 molecules = 1 MOLECULAR mass

1 mole = wt/mol.wt

mol. wt of SeO2 = 79+32 = 111 G

no.of moles that 22 g of SeO2 = 22 / 111 = 0.1982 moles

therefore no. of molecules = 0.1982 x 6.023 x 10^23

= 1.194 x 10^23 molecules.

COVALENT compounds are formed by covalent bonds. Covalent bonds are formed by sharing of electrons. Due to this bond strength is comparatively weak than ionic compounds.

In a covalent compound, the bond strength between atoms are strong. But the Inter molecular force of attraction is less. Due to this they have low MELTING points and boiling points.

Since low melting points are mostly between the ROOM temperature, the covalent compounds exist as liquids in room temperature. Some compounds have low boiling points also less than room temperature. Hence they exist as gases.

Exceptions are Diamond which is a covalent compound having high melting and boiling point. This is because in diamond the inter molecular force of attraction between CARBON is strong enough to remain INTACT. Hence they need high energy for breaking bond. Due to high Bond disassociation energy they have high melting and boiling point.

If you KNOW the FORMULA is
2n^2

The METAL s are DEPOSITED at the cathode and CHLORINE is LIBERATED at anode

In chemistry, catenation is the bonding of ATOMS of the same element into a series, called a chain. ... Catenationoccurs most readily with carbon, which forms covalent BONDS with othercarbon atoms to form longer CHAINS and structures. This is the reason for the presence of the VAST number of organic compounds in nature.

Weight of solution =weight of solute(SUGAR) +weight of solvent (water)=7GM +93gm=100gm.

hope it HELPS you.

Hey
In molten state electrons are not able to move freely in the CONTAINER which stops them from passing electricity. But in aqueous SOLUTION they can move freely to PASS current FORM one electrode to other.

Hope it HELPS :))

<P>Given:

1. Moles of A = 1

2. Moles of B = 3

3. Vapor pressure = 300 mm

4. New Vapor pressure upon adding one mole of A = 290 mm

To find:

Vapor pressure of pure A

Solution:

• We know that, P = Xa x PA + Xb x Pb

                            300 = 1 / (1+3) Pa + 3 / (1+3) Pb

                            300 = 0.25Pa + 0.75Pb                            eq(1)

• Now, when 1 mole of A is added, then,

       290 = 2 / (2+3) Pa + 3 / (2+3) Pb

       290 = 0.4Pa + 0.6Pb                                                     eq(2)

• On SOLVING eq(1) and eq(2), we get,

        Pa = 250mm

• Thus, the vapor pressure of pure A is 250 mm.

It is ACTUALLY a MIXTURE of both. the container cases Deputy CONDUCTION and the WATER BOILS due to convection.

The atoms can be of the same element or DIFFERENT elements. In each MOLECULE, thebonds between the atoms are strong but thebonds between molecules are usually WEAK. ...Compounds withcovalent bonds may besolid, LIQUID or gas at room temperature depending on the number of atoms in the COMPOUND.
