Answer:
Keq = 0.053
7.3 kJ/mol
Explanation:
Let's consider the following isomerization reaction.
glucose 6‑phosphate ⇄ glucose 1 - phosphate
The concentrations at equilibrium are:
[G6P] = 0.19 M
[G1P] = 0.01 M
The concentration equilibrium constant (Keq) is:
Keq = [G1P] / [G6P]
Keq = 0.01 / 0.19
Keq = 0.053
We can find the standard free energy change, ΔG°, of the reaction mixture using the following expression.
ΔG° = -R × T × lnKeq
ΔG° = -8.314 J/mol.K × 298 K × ln0.053
ΔG° = 7.3 × 10³ J/mol = 7.3 kJ/mol
The atom has a tiny and heavy nuclues as well-know gold foil.
The kind of radioactive element is useful for dating an object is one with a half-life close to the age of the object.
<h3>What are radioactive elements?</h3>
Radioactive elements are elements that involved in radioactivity and this comprises of atoms or particles in their nuclei whose atomic nuclei are not stable and they emit radiations to maintain stability.
Therefore, The kind of radioactive element is useful for dating an object is one with a half-life close to the age of the object.

Answer:
The resulting molarity is 6M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We use the formula for dilutions:
C1 x V1 = C2 x V2
12 M x 0,5L = C2 x 1,0 L
C2= (12 M x 0,5 L)/1,0 L
<em>C2= 6 M</em>
The complete chemical reaction of aqueous Sodium sulfate and aqueous Barium nitrate is
The right side and the left side of the reaction have equal number of elements, therefore it is balanced.
