<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

\huge\boxed{Sublimation}

<h2>_____________________________________</h2><h2>Sublimation:</h2>

Sublimation is a process in which the solid molecules gain energy from their surrounding and they now have enough energy to overcome the force of attraction with the neighboring molecules, thus they escape into the surrounding without going through the liquid phase, that means they directly jump to the vapor phase.

<h2>_____________________________________</h2><h2>Endothermic</h2>

Those process which absorb energy from their surrounding to form the product are called endothermic process. Since the SUBLIMATION requires additional energy, it is an endothermic change.

The energy that is released when hydrogen ions pass through ATP synthase provides the energy needed to form ADP and phosphate fr
MArishka [77]

Answer:

True.

Explanation:

This process is known as chemiosmosis in which there is a movement of ions across semipermeable membrane. Hydrogen ions moves from region of its higher concentration to the region of lower concentration.  As this process belongs to the diffusion or osmosis of water molecules across cell membrane that is why known as chemiosmosis.

ATP synthase is an enzyme which function is to form ATP by using free energy generated in result of movement of hydrogen ions.

The half-cell is a chamber in the voltaic cell where one half-cell is the site of the oxidation reaction and the other half-cell
SashulF [63]

Answer:

See below  

Explanation:

The half-cell reduction potentials are

 Ag⁺(aq) +   e⁻ ⇌ Ag(s)     E° =  0.7996 V

Co²⁺(aq) + 2e⁻ ⇌ Co(s)     E° = -0.18      V

To create a spontaneous voltaic cell, we reverse the half-reaction with the more negative half-cell potential.

We get the cell reaction :

Anode:     Co(s)                 ⇌ Co²⁺(aq) + 2e⁻

<u>Cathode: 2Ag⁺(aq) +   2e⁻ ⇌ 2Ag(s)                  </u>        

Overall:  Co(s) + 2Ag⁺ (aq) ⇌ Co²⁺(aq) + 2Ag(s)
