Answer:
C. The reaction is energetically favorable.
Explanation:
The reaction which shows the removal of the terminal phosphate from the ATP is shown below:
The Gibbs' free energy change of this reaction,
Hence, Option A is not correct.
It is a type of hydrolysis reaction in which water is being added to the molecule.
Hence, Option B is not correct.
The Gibbs' free energy change is negative which means that the reaction is energetically favorable.
Option C is correct.

Explanation:
Metals are the species which readily lose electrons in order to attain stability. This electron lost by the atom is actually present in its outermost shell which is also known as valence shell.
Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.
When we move across a period from left to right then there occurs a decrease in atomic size of the atoms. Therefore, ionization energy increases along a period.
But when we move down a group then there occurs an increase in atomic size of the atoms due to addition of number of electrons in the atoms. Hence, ionization energy decreases along a group.
Thus, we can conclude that metals have low ionization energies and readily share their valence or outer electrons with each other to form an electron sea. These electrons are delocalized or shared among all the atoms that are bonded together and can therefore move freely throughout the metal structure.
The formula mass of MgCl - atomic mass of Mg + 2(atomic mass of Cl)
formula mass - 24.3 + (35.45x2) = 95.2
In 95.2 of MgCl₂ - there are 6.022 x 10²³ formula units of MgCl₂
Therefore in 15.0 g of MgCl2 - there are 6.022 x 10²³ /95.2 x 15.0 = 9.49 x 10²² formula units of MgCl₂
the number of formula units - 9.49 x 10²² formula units of MgCl₂
