ANSWER:

the addition compounds which retain their IDENTITY in SOLUTION are called complex compounds and coordination compounds . ... Coordination compounds are ionisable, i.e. they will dissociate into cation and anion, but the coordination entity is RETAINED

Explanation:

The electron withdrawing groups PRESENT on both sides ATTRACT the electron towards themselves and THUS weaken the –CH bond of methylene. Thus hydrogen atom can DISSOCIATE to give a stable anion. ... Thus methylene group attached to TWO electron withdrawing functional groups is termed as reactive methylene group.

Mg 2+ has the larger hydration energy, because hydration energy increases with the CHARGE on the cation and decreases as the SIZE of the cation increases. THEREFORE answer is Na + .

Hope it's HELPFUL.

Answer:

12.011 AMU

We can equate the numerical QUANTITY of the mass of a single ATOM (in amu) to the mass of a mole of the same atoms (in grams). 1 carbon atom has a mass of 12.011 amu. 1 mole, or carbon atoms (6.022x 1023 carbon atoms) has a mass of 12.011 grams.

Answer:

I have given the STRUCTURE of HISTAMINE including the HYDROGENS. HOPE it HELPS

Explanation:

HISTAMINE is a member of the CLASS of imidazoles that is 1H-imidazole SUBSTITUTED at position C-4 by a 2-aminoethyl group. It has a role as a HUMAN metabolite, a mouse metabolite and a neurotransmitter. It is an aralkylamino compound and a member of imidazoles.

PubChem CID: 774

Molecular Formula: C5H9N3

Molecular Weight: 111.15

Answer:

The reducing character of hydrides of group 15 elements increases from top to bottom because the E-H strength (Here E= N, P, As, Sb, or Br) bond decreases down the group due to an increase in the size of the central atom.

Reason

The stability of hydrides decreases down the group from NH3 to BIH3. This is due to a decrease in their bond dissociation enthalpy.  Reducing character is directly related to the ease of losing HYDROGEN. NH3 is a mild reducing agent, and BiH3 has the strongest reducing character amongst all hydrides of group 15.

The trend of group 15 HYDRIDE based on reducing character is as given below.

BiH3 > SbH3 > AsH3 > PH3 > NH3

Stability decreases down the group as the bond dissociation energy decreases.

Hence, the bond dissociation energy decreases down the group due to the increase in the central atom size.

The hydrides of these elements are pyramidal with a lone pair of electrons in one of the ORBITALS. The bond angles GRADUALLY decrease due to a decrease in bond pair-bond pair repulsion on moving down the group.

As nouns the difference between pentyl and amyl

is that pentyl is (ORGANIC CHEMISTRY) either of several isomeric univalent hydrocarbon radicals, c5h11, FORMALLY DERIVED from pentane by the loss of a hydrogen ATOM while amyl is (dated|organic chemistry) pentyl.

Answer:

If they do not mix, then they can be separated using GRAVITY. There are special SEPARATION funnels for that KIND of operation. If the TWO liquids mix, or dissolve in each other, the difference in density is irrelevant and you need to find other WAYS to separate them.
