Salinity has units of grams NaCl or salt per kilogram solution. We can use the density given and the molar mass of the salt to convert from salinity to molarity. We do as follows:
( 5.6 g / kg ) ( 1.03 kg / L ) ( 1 mol / 58.44 g ) = 0.0987 mol NaCl / L
Ionization energy is the energy required to remove an electron from a gaseous atom or ion. The first or initial ionization energy or Ei of an atom or molecule is the energy required to remove one mole of electrons from one mole of isolated gaseous atoms or ions
Answer:
Explanation:
Among the most recent systems for the exploitation of geothermal energy, the most promising are the third generation ones, also called EGS (Enhanced Geothermal Systems). Their technology allows to dramatically improve energetic efficiency of both geothermal wells and dry rocks.

Answer:
The correct answer is option D.
Explanation:
When a chemical reaction proceeds the reactants are converted into products. The energy hill represents the potential energy of the reaction.
There are two conditions: If the reaction is endothermic than the energy of the products is greater than the energy of the reactants and ΔH is positive. This energy gain is shown in the form of a peak. In an exothermic reaction, the energy of the products is lower than the reactants and ΔH is negative.
So the suitable option is D which states that the reaction is endothermic and the potential energy gained by the products is higher when a reaction proceeds.
