Answer:
Explanation:
In this case, for the dissociation of hypochlorous acid, we know that the acid dissociation constant (Ka) is 2.9x10⁻⁸, which is related with the Gibbs free energy as shown below:
But in this case K is just Ka, therefore, at 296 K, it turns out:
Such result, means that the reaction is nonspontaneous at the given temperature, it means it is not favorable (not easily occurring).
Best regards.
Atomic number = 127 – 53=74 neutrons
The answer is B. uniform in composition.
We are tasked to find the percent error of the jeweler's density measurement through the formula:
%Error= Absolute Value(Experimental Value - Theoretical value) x 100%/ Theoretical Value
We are given by the problem,
Experimental Value=20.3 g/cm3
Theoretical Value= 19.3 g/cm3
By Substituting the details,
%Error= Absolute Value(20.3 g/cm3 - 19.3 g/cm3) x 100% / 19.3 g/cm3
%Error=Absolute Value (1)/19.3
%Error= 100/19.3
%Error= 5.18%
Therefore, 5.18% is the percent error committed by the jeweler<span />
