Which term names the concentration of salts dissolved in a liquid?
Viefleur [7K]
Hey there!
The answer is D, Salinity.
Salinity is the concentration of salt in water. Ocean water often has high salinity and this can contribute to things like upwelling and water density- but these all start from salinity.
Hope this helps!

Consider the fructose-1,6-bisphosphatase reaction. Calculate the free energy change if the ratio of the concentrations of the pr
enot [183]

Answer:

ΔG = -8.812 kJ/mol

Explanation:

To obtain the free energy of a reaction you can use the expression:

ΔG = ΔG° + RT ln Q

<em>Where: </em>

<em>ΔG° is Standard Gibbs Free energy: -16.7kJ/mol = -16700J/mol</em>

<em>R is gas constant: 8.314472 J/molK</em>

<em>T is absolute temperature (37°C + 273.15 = 310.15K)</em>

<em>And Q is reaction quotient: 21.3</em>

<em />

Replacing in the formula:

ΔG = ΔG° + RT ln Q

ΔG = -16700J/mol + 8.314472J/molK*310.15K ln 21.3

ΔG = -8812.4J/mol

<h3>ΔG = -8.812 kJ/mol</h3>
