Because the DISPERSED PARTICLES of a colloid are not as large as those of a  suspension they do not settle out upon standing . .... The dispersed particles of a colloid cannot be separated by filtration but they scatter light  a phenomenon CALLED the TYNDALL effect

Hey dude
the valence SHELL of an isolated gaseous atom in its ground state resulting in the FORMATION of ion whereas, electron gain enthalpy is the amount of ENERGY associated with the gain of ELECTRONS by the isolated gaseous atom. So,it is opp. of I.E Hence,if I.E of Na=5.1 its Electron Gain enthalpy will be -5.1

Hii There!!
Combination Reaction:-
When two or more reactants combine to form a single product.
Such reaction is combination Reaction.

for ex:- when magnesium ribbon burns in AIR it COMBINES to form Magnesium OXIDE
=) Mg+O2-->MgO



Decomposition Reaction:-
When one reactant decomposes into two or more reactants or products then such reaction is known as Decomposition Reaction.

Like:-WATER can be broken down into hydrogen gas and oxygen gas
=) H2O---> H2+O2

1.Terylene fiber is used as POLYESTER tricot knit as a FASHION garments fabric.
2.Used for the LAUNDRY usage as a automatic clothing vacuum packaging machine
3..It is used to make nonwoven NEEDLE punched carpet PARTICULARLY for the exhibition use......

It is a fact that after a chemical REACTION, the chemical properties of the PRODUCT are DIFFERENT than that of the REACTANTS. So, water doesn't have the same properties as oxygen and HYDROGEN.

Acids and BASES on DILUTING release H+ or OH- IONS..
they both conduct ELECTRICITY..

1.particles have interpatticle force
2. they are constantly moving
3. they have interpartocle SPACE

The Bohr atomic model theory made correct PREDICTIONS for smaller sized atoms like HYDROGEN, but POOR spectral predictions are OBTAINED when larger atoms are considered.It failed to explain the Zeeman effect when the spectral LINE is split into several components in the presence of a magnetic field.It failed to explain the Stark effect when the spectral line gets split up into fine lines in the presence of electric field.

4 heating of something (object) is not everytime needed...so..... temperature remains contant or U can SAY in easy kanguage that is AS IT IS.

Here is your answer

electron revolves around nucleus in circular path is called as orbit
Energy of an electron in ONE of its allowed orbits is fixed.As long as an electron remains in one of its allowed orbit, it can not absorb or radiate energy.If an electron jumps from lower energy level to a higher energy level, it absorbs a definite amount of energy.
. If an electron jumps FORM higher energy level to a lower energy level, it radiates a definite amount of energy.

nergy released or absorbed by an electron is equal to the difference of energy of two energy levels.
Let an electron jumps from a higher energy level E2 to a lower energy level E1.The energy is EMITTED in the form of light .Amount of energy released is given by:

E = E2 - E1
E2 - E1= hv
Where 
h = Planck's consrant ( 6.6256 x 10-34 j.s)
V = Frequency of radiant light

6. Spectrum of light emitted from an electron is a "LINE SPECTRUM".7. Angular momentum of an electron is given by:

m v R = nh /2π

Where n =1, 2, 3, ………..

m = mass of electron

V = velocity of electron

r = radius of orbit

Because in the water PARTICLES there is space between them and the particles of SUGAR can FILL the whole space

Hey!
UR answer is :-

DIFFUSIONS of gases TELL US bout the "movements of particles" in gases are higher than as comparw to solids nd LIQUIDS .

Hii
mass of 1.5 litres or 1500 mL of water = 1500g.
(USING the relation density = mass / VOLUME)
The molar mass that is the mass of 6.022 X 1023 molecules of water is 18g.
Plz mark my brainlist

Because we can't DIFFERENTIATE the COMPONENTS of AIR PHYSICALLY....

This is ANSWER of your QUESTION

The AVERAGE ATOMIC MASS of BROMINE is 79.90

Hi there!

The molar mass that is the mass of 6.022 ×  atoms of HELIUM is 4g. 

Hence 1 mole of He = 4 g of He = 6.022 × atoms of  He

1 g of He = (6.022 × ) / 4 atoms of  He

52 g of He = (6.022 × × 52 ) / 4 atoms of  He

= 7.829 × atoms of Helium [ He ]

Hope it HELPS! :D

The SYMBOL of COBALT is CO.

Avogadro's number, number of units in one mole of any substance (defined as its molecular WEIGHT in grams), equal to 6.022140857 × 1023. The units MAY be ELECTRONS, atoms, ions, or molecules, depending on the nature of the substance and the CHARACTER of the reaction.

Hope it helps...UH...out

The FORMULA of the CHLORIDE of E is ECl4

CH4 [g] +2O2 [g] _ _ _ _ > CO2 [g] +2h2O [g] Now according to the reaction of 1 mole of CH4 gives 2moles of H20. And 16 grams of METHANE mean 1 mole [moles = given MASS/ MOLECULER mass . Moleculer mass of methane is16]

It is because in FLAT PLATE more heat energy is lost in the form of STEAM as compared to GLASS

No. of ATOMS= GIVEN mass × Avogardo number
Here,
3.011×10^(23) = Mass of Ag (Silver) × 6.022×10^(23)
HENCE,Mass of Silver lamp = 1/2 G= 0.5 g
Therefore, cost of lamp= Rs. 30

In distilled WATER there are no charges particles or ions to CONDUCT electric CURRENT
Hence distilled water is a POOR conductor of ELECTRICITY

Matter are being classified in THREE states solid liquid and gas..
the molecules are tightly PACKED in solis loosely in liquid and far away in gases
solids are not FLUID but liquid and gases are....
solid and liquid doesnt fills the container completely while gases fills and LIQUIDS anf gases aquires the shape of the container in which it is filled..
hope this will HELP u....

Hello Friend....

The ANSWER of u r question is......

"Water molecules FORMING hydrogen bonds with ONE another.T he partial negative charge on the o of 1 molecule can form a hydrogen bond with partial positive charges on the hydrogen of the molecules. water molecules are also attract to other polar molecules and to IONS....."

Thank you...
