Because it HELPS the CURRENT to PASS through a PARTICULAR THING

atomic theory is a scientific theory of the nature of matter which states that matter is composed of discrete units CALLED atoms. It began as a philosophical CONCEPT in ancient Greece and ENTERED the scientific MAINSTREAM in the early 19th century when discoveries in the field of chemistry showed that matter did indeed behave as if it were MADE up of atoms.

When Sulphur is heated with rubber, the process is comm - General Knowledge Today. When Sulphur is heated with rubber, the process is commonly known as ? Notes: Natural rubber BECOMES SOFT at high temperature (>335 K) and brittle at LOW temperatures (<283 k) and SHOWS high water absorption capacity

YES, it is a colloidal solution of fat (globules) in MILK. Milk appears to be a HOMOGENEOUS mixture, it is a colloid because it has small globules of fat and protein that do not settle out after standing due to the PARTICLES (usually NEGATIVELY) charged particles.

No, it will be electrically NEUTRAL as the NUMBER of electrons and PROTONS will be same and hence it will have no charge.

When BONDS are formed ENERGY is RELEASED because NEW chemical bonds are formed.

Hey
________

Neils bohr when he saw rutherfords theory he was not covinced

•if a charged body is in motion it radiates ENERGY, electron which is moving around the nucleus , it continuously looses energy and hence it moves closer to the nucleus and collides with the nucleus

•rutherford atom was not able to explain the stability of the atom

•he gave his atomic model in 1930

•a/q to him electrons move around nucleus in definite ORBITS , in this particular orbits, they revolve WITHOUT loosing energy

•the electrons who are closer to the nucleus are attracted with greater FORCE, and who are not closer are attracted with lesser force

•it requires fixed amount of energy to move the electron from its nearer position from away the electron

•he gave a formula 2n^2 to calculate the no of elactrons in the shells

hope helped

Alkanes only have single bonds THUS they are less reactive than the other HYDROCARBONS HENCE functional groups are added to the alkane GROUP

Petroleum Composition. Most people presume petroleum to be SIMILAR to gasoline or petrol, simply a less pure FORM, which NEEDS to be refined

Your question SEEMS to be incomplete but what I would like to let you know is that depression of freezing point is a colligative property is that it is only dependent on the ratio of the number of solute particles present to the number of solvent molecules and not in any way the nature of the chemical species present.

So when handling this question put that HIGHLIGHT in the back of your mind.

Other colligative properties you may ALSO come ACROSS are BOILING point elevation, those dealing with pressure and osmotic pressure.

Charles’ law STATES that volume of a given mass of a gas increases or decreases by 1/273 of the volume at 0°C for each degree RISE or fall in TEMPERATURE respectively, provided PRESSURE is kept constant.

✔ RUTHERFORD'S GOLD FOIL EXPERMIENT ➡ Lord Rutherford, a scientist from New Zealand directed a stream of alpha particles towards a very thin gold foil. He selected a gold foil because he wanted as thin a layer as possible and also gold is the most malleable metal.

✔ OBSERVATION

➡ (1) Most of the alpha particles passed straight through the foil.

➡ (2) Some alpha particles were slightly DEFLECTED from their straight path.

➡ (3) Very few alpha particles were EITHER deflected by very large angles or completely bounced back.

✔ CONCLUSION

➡ Heavy metals such as platinum will show the same observation with alpha particles as shown by gold foil, but if light NUCLEI like lithium is used then fast moving alpha particles may even push the light nucleus ASIDE and may not be deflected back.

S ORBIT has ONE orbital, P orbit has three ORBITALS, d orbit has five orbitals, and F orbit has seven orbitals....hope it helps you....

I THINK CO2 will be.

Because carbon posses two important PROPERTIES
catenation-self linking PROPERTY to have C-C bonds
tetravalency-it has VALENCY of 4.It combines with other ELEMENTS to ATTAIN stability

Rancidity is complete or INCOMPLETE oxidation or hydrolysis of FATS an OILS when EXPOSED in air

It’s ELECTRON will TRANSFER from n=n to n=3

:P1 = 5 atm
T1 = 273 K ;
T2 = (273 + 546) K= 819 K
V1 = V1
V2 = V1/3
Combining the gas laws, we obtain
P1V1÷T1=P2V2÷T2
or P2=P1V1×T2÷V2×T2
=>now SUBSTITUTING value
=>5×V1×819÷V1/3×273
=>5×819×3÷273 ( V1 cancelout with V1)
=>45atm

Hope it will help you!!!

Microbs are small ORGANISMS that cannot be SEEN with naked EYES.

1. because it completely mixed with WATER
2. we can find it because SALT completely mixed with water do not GIVES WHITE colour but chalk gives
3. because all seeds were passed through sieve
4. because all clouds gets converted into water and pollutants fall down with rain water

Because it was only APPLICABLE UPTO CALCIUM ie. lighter elements only.

Unit CELL of NACL CONTAINS 23 Sodium IONS and 35 chlorine ions.

Steric hindrance is the stopping of a CHEMICAL reaction which might be caused by a MOLECULE's structure.An example of steric hindrance is how rotaxances are created.
