<span>Acetic acid is under the family
of carboxylic acids which has a carboxyl group –COOH bond attached to the alkyl
group. Alkyl group can be methyl (CH3-), ethyl (CH3CH2-) and so on. The term
acetic also means methyl. So combining the two gives CH3COOH or HCH3CO2. The H
before the C in <u>H</u>CH3CO2 means that it is the H attached to the O in the carboxyl
group –COOH. You cannot write it as C2H4O2 because it would represent a
different compound.</span>
The chemical formula of nickel (ii) hypochlorite is Ni(CIO)2. Nickel (II) has a charge of +2 while (CIO-) which is a poly atomic ion of chlorine and oxygen has a charge of -1. After balancing the charge of nickel with that of CIO- you get the chemical formula as Ni(CIO)2.
Hey there!:
The fractional saturation y is defined as :
y = [ L ] / Kd + [ L ]
where :
[ L ] = concentration of binding ligand
Kd = 400 nm
The answer is D because there is no forces of attraction or repulsion between gas particles .
Answer : The enthalpy change for the solution is 166.34 kJ/mol
Explanation :
First we have to calculate the enthalpy change of the reaction.
Formula used :

where,
= change in enthalpy = ?
C = heat capacity of water = 
m = total mass of sample = 2.174 + 127.4 = 129.6 g
= initial temperature = 
= final temperature = 
Now put all the given values in the above expression, we get:


Now we have to calculate the moles of AX added to water.

Now we have to calculate the enthalpy change for the solution.
As, 0.04592 moles releases heat = 7638.36 J
So, 1 moles releases heat = 
Therefore, the enthalpy change for the solution is 166.34 kJ/mol
