What is Gibbs free energy
Alenkinab [10]

Answer:

The minimum amount of energy needed the the cell to perform various cellular,biochemical and physiological activities is known is Gibbs free energy.

Explanation:

The change in gibbs free energy of is very much important to determine whether a given reaction is spontaneous,non spontaneous  or equilibrium.

 1 If gibbs free energy change of a reaction is negative then the reaction is spontaneous.

2  If the free energy change is 0 then the reaction is in equilibrium stage.

3  If free energy change is positive then the reaction is non spontaneous.

What is the law of conservation and what happens when two substances at different temperatures come into contact.
insens350 [35]

Answer:

- Both energy and matter cannot be neither created nor destroyed.

- An equilibrium temperature will be reached.

Explanation:

Hello,

In this case, the law of conservation is applied to both matter and energy, and it states that both energy and matter cannot be neither created nor destroyed. Specifically, in chemical reactions, it states that in closed systems, the mass of the reactants equals the mass of the products even when the number of moles change. Moreover, for energy, if two substances at different temperatures come into contact, the hot one will cool down and the cold one will heat up until an equilibrium temperature so the energy lost by the hot one is gained by the cold one, which accounts for the transformation of energy.

Best regards.

Explain the trend in atomic radius as you progress up column 17
frutty [35]
As you progress up any column on the periodic table the atomic radius gets smaller. Fluorine is a very small atom because it has very few electrons and Iodine is a very large atomic radius because it has many electrons.
