Answer:
Energy of the reaction = -848.94KJ/mol
Explanation:
The Gibb's free energy also referred to as the gibb's function represented with letter G. it is the amount of useful work obtained from a system at constant temperature and pressure. The standard gibb's free energy on the other hand is a state function represented as Delta-G, as it depends on the initial and final states of the system. The spontaneity of a reaction is explained by the standard gibb's free energy.
The step by step calculation is shown in the attachment.
Answer:
the chemical composition of a substance.
Explanation:
I am pretty sure that is exactly what you need. Proton in there should either gain or loss from the carbon, as there is <span>resonance stabilization. Do hope you still need the answer, because this one is really helpful. Regards!</span>
<span>Symbol- Cr
Oxidation States: 6, 3, 2, 0
Chromium is unstable in oxygen, it immediately produces a thin oxide layer that is impermeable to oxygen and protects the metal below. </span>
Let us write succinic acids as H2Suc
The first ionization is
H2Suc ----> HSuc- + H+
The seond ionization is
HSuc- ----> Suc-2 + H+
Calculate the H+ concentration of from the first ionization using pKa1.
Then, calculate the H+ concentration from the second ionization using pKa2.
Next, use the buffer equation to calculate the concentration of the salt in the solution. Then, use the given volume to get the number of moles of the salt. Finally, use the given molecular weight to get the mass.
