They have DIFFERENT boiling POINT. This is KNOWN as fractional DISTILLATION

In SOLID state molecules are hard , HIGHLY reactive and in gasses molecules are in EXPANDED form and after reaction it relased in AIR

When gas becomes cool ... there intermolecular forces increases and intermolecular DISTANCES decreases and it CHANGES to LIQUID state ... and then by cooling more ... it changes to solid ...

Because ice have small INTRA molecular SPACE in which AIR is FILLED that's why it's FLOATS on water

It's here I just GOT it is didn't STUDY this

The ANS is RED COLOUR

This is done in the case of oil paints!
When the paints are new and fresh, they have a layer of oil COATING above them. Once we shake the paint BOTTLE, the oil GETS MIXED properly....Hence PAINTING comes out to be smudge free!!!

Nitrogen is TRIVALENT it forms 3 bonds with HYDROGEN. .. but nitrogen also have a lone PAIR it shares with another hydrogen to form ammonium ion...
Hope it helps you ... Mark as BRAINLIST plz

I THINK ANSWER is 33.68ok

The RIGHT ANSWER is here. .WATCH it ..HOPE it HELPS.

It is UNBALANCED REACTIONS FIRSTLY BALANCE then you will have your ANSWER

Nitroalkane in the PRESENCE of SnCl2 and HCl GETS reduced to form the corresponding 'Alkanamine'.
HOPE this helps.....

When the solid is heated then the molecules of solid STARTS COLLIDE as a RESULT it melts

Answer:

When heated Copper Carbonate reacts with Oxygen to form copper DIOXIDE and carbon dioxide.

Explanation:

A BLACK residue is FORMED which has different PROPERTIES then Copper Carbonate and Oxygen.

This probably didn't help but K

N-methylmethanamine is a stronger BASE than methyl amine.
This is because of the +I effect of the two methyl groups in N-methylmethanamine which increases the electron density on the N-atom making the CARBOCATION intermediate more STABLE.
In methyl amine, there is only one methyl group. THUS, it has less electron density increase than N-methylmethanamine and hence the carbocation intermediate is less stable.
We know, greater the stability of the intermediate stronger is the base.
Thus, N-methylmethanamine is more stable than methyl amine. (This is the case when the COMPOUNDS are in gaseous phase)

DIAMOND is non-conducting but graphite is conducting.
This is because in diamond, ONE C-atom is bonded to 4 other carbon atoms in a tetrehedral manner and there are no free electrons to allow FLOW of ELECTRICITY.
On the other hand, in graphite, one C-atom is bonded to 3 other C-atoms and there is one free electron for each C-atom. This electron is free to move and thus, allows the flow of electricity.
HENCE, graphite can conduct electricity unlike diamond

The PROPERTY is CALLED LUSTRE

We can USE the PROCESS of EVAPORATION..

When we are MELTING the SUGAR in WATER then it MELT EASILY

The electronic configuration of SC whose ATOMIC NUMBER is 21 is 2883

A DIVER is able to CUT through WATER in a swimming POOL because being a liquid it has weak INTER mlecules force of attraction between the molecules. Adiver is able to cut through water in aswimming pool.It shows that particles of matter have space between them.

I THINK this REACTION TAKE PLACE only in SUNLIGHT

In CHEMICAL kinetics , we learn that in a reversible reaction ,both the forward reaction and reverse reaction OCCUR at the same time. At equilibrium , the rates are the same. For example:Production of AMMONIA NH3 .During the production of ammonia both the forward & reverse reaction is present .

3H2(g)+N2(g)⟶2NH3(g)3HX2(g)+NX2(g)⟶2NHX3(g) forward reaction

2NH3(g)⟶3H2(g)+N2(g)2NHX3(g)⟶3HX2(g)+NX2(g) reverse reaction

Now come to the Gibbs free energy.

Under standard condition(298K) , it can be calculated that the reaction is forwardly favored (forward reaction is spontaneous,and thus the decomposition of NH3 is non-spontaneous). I UNDERSTAND H2 and N2 will produce more NH3.My question is at this situation will NH3 decompose into H2 and N2 to some EXTENT(though it is a non-spontaneous process)?.But chemical kinetics tells that both reaction(not necessarily same rate) have to be present to create equilibrium in future.

a reaction in which a single compound decomposes into 2 or more substances is CALLED decomposition reaction.

application : seperation of substances

Hey Ahaana29,

A CHEMICAL equation is the symbolic representation of a chemical reaction in the form of SYMBOLS and formulae, WHEREIN the reactant entities are given on the left-hand SIDE and the product entities on the right-hand side.

hope dis helps u!

with regards,

It would be BASE. As metal OXIDES are GENERALLY BASES.

A mixture is said to be homogeneous if the solute particles are DISSOLVED COMPLETELY.for EXAMPLE sugar in water ,salt in water these are soluble in water are called true solution...but a mixture is said to be heterogeneous If the size of solute particles are not completely dissolved.for example CHALK and water ,muddy water et cetera .......

Because it is more REACTIVE SUBTANCE

In SO2 the no of MOLES 0.00025

no. MOLES of NH3= (6×10^21)/(6×10^23)

=10^-2 or 0.01

no. moles of C = (5×10^21)/(6×10^23)

= 0.83×10^-2

no. of moles of N= (6.023×10^11)/ (6.023×10^23)

= 10^-12
