Answer:

The correct answer is c. 30%

Explanation:

Groundwater is that found below the earth's surface. Groundwater is contained in aquifers. An Aquifer is a geological formation or a part of it, consisting of a permeable material capable of storing a certain significant amount of water. Aquifers can consist of different material, such as sedimentary permeable rocks such as sand stones or mud stones.

In general, it maintains a temperature very similar to the annual average in the area, therefore, in arctic regions, it can freeze.

Groundwater represents around 30% of the world's fresh water.

<u><em>The correct answer is c. 30%</em></u>

Using the thermodynamic information in the ALEKS Data tab, calculate the standard reaction free energy of the following chemical
julia-pushkina [17]

Answer:

43.0 kJ

Explanation:

The free energy (ΔG) measures the total energy that is presented in a thermodynamic system that is available to produce useful work, especially at thermal machines. In a reaction, the value of the variation of it indicates if the process is spontaneous or nonspontaneous because the free energy intends to decrease, so, if ΔG < 0, the reaction is spontaneous.

The standard value is measured at 25°C, 298 K, and the value of free energy varies with the temperature. It can be calculated by the standard-free energy of formation (G°f), and will be:

ΔG = ∑n*G°f products - ∑n*G°f reactants, where n is the coefficient of the substance in the balanced reaction.

By the balanced reaction given:

2NOCl(g) --> 2NO(g) + Cl2(g)

At ALEKS Data tab:

G°f, NOCl(g) = 66.1 kJ/mol

G°f, NO(g) = 87.6 kJ/mol

G°f, Cl2(g) = 0 kJ/mol

ΔG = 2*87.6 - 2*66.1

ΔG = 43.0 kJ
