P−aminobenzenesulfonic acid (sulfanilic acid) is normally written in the form shown but its zwitterionic form is more stable. wr
ite a structural formula for the zwitterion.
1 answer:
Zwitterion is an ion consists of equal positive and negative charges on the same molecule which make it more stable and has high melting point
p-aminobenzene sulfonic acid contains both acidic (-SO₃H) and basic groups (NH₂), the acidic group will lose one proton to give (-SO₃⁻) and the basic group will gain this proton to give (-NH₃⁺)
The structure is:

Answer : The specific heat (J/g-K) of this substance is, 0.780 J/g.K
Explanation :
Molar heat capacity : It is defined as the amount of heat absorbed by one mole of a substance to raise its temperature by one degree Celsius.
1 mole of substance releases heat = 92.1 J/K
As we are given, molar mass of unknown substance is, 118 g/mol that means, the mass of 1 mole of substance is, 118 g.
As, 118 g of substance releases heat = 92.1 J/K
So, 1 g of substance releases heat =
Thus, the specific heat (J/g-K) of this substance is, 0.780 J/g.K
Answer:
0.6410g of HgS (mercury (II) sulfide) are formed
Explanation:
First you should write the balanced chemical equation, so we have:
Where:
is the formula for the sodium sulfide
is the formula for the mercury (II) nitrate
is the formula for the mercury (II) sulfide
and
is the formula for the sodium nitrate
Then you should calculate the amount of each substance in each solution, so:
- For the :
moles of
- For the :
moles of
As the quantity of is smaller than the quantity of
. The
is the limiting reagent and you should work with this quantity, so we have:
moles of HgS
And as the molar mass of the HgS is you can calculate the mass of HgS that is produced:
HgS
Explanation:
The reaction equation will be as follows.
It is given that the total energy liberated is -2810 kJ/mol. As the sign is negative this means that energy is being released. Also, it is given that the energy required to synthesis is -64.1 kJ/mol.
Therefore, calculate the number of moles of compound as follows.
No. of moles =
=
= 43.83 mol
= 44 mol (approx)
Thus, we can conclude that the number of moles of compound is 44 mol.
