Answer:

It is very important to known about the chemical reactions that takes place around us.

There are various types of chemical reactions taking place in our every day life. The burning of match stick, rusting of iron are chemical reactions that takes place in the body of organisms.

The compounds react together to form essential products which is formed. The matter that is formed in nature is combination if elements. Water and carbon dioxide form carbohydrates.

This is an example of combination of elements. There are many more examples which are seen in day to day life.

Scientist believe that about 25 of the known elements are essential to life. Just four of these - Carbon (C), Oxygen (O), Hydrogen (H), and Nitrogen (N), - make up about 96% of the human body.


These four elements are found in the basic structure of all biochemical molecules. For example, Glucose is a carbohydrate and it's molecular formula is C6H12O6 - each molecule of glucose is made up of 6 Carbon atoms, 12 Hydrogen atoms and 6 oxygen atoms.


The other elements found can be divided into two main groups - major elements and trace elements.


The human body functions as a result of a large number of the chemical reactions involving compounds of a of these elements.

On the basis of the information below, the dissolution of FeF2(s) in acidic solution is A. thermodynamically favorable, because
antoniya [11.8K]

Since K3 is greater than 1, the reaction is thermodynamically favorable.

Data;

  • FeF2 is in an acidic solution
  • K2 > 1 is thermodynamically favorable
  • k3 > 1 is not thermodynamically favorable
  • K1<1 is not thermodynamically favorable

<h3>Hess Law</h3>

This states that the heat change in a given chemical reaction is the same irrespective of the number of process in which the reaction is effected.

Using Hess Law;

rxn_3 = rxn_1 * 2rxn_2\\k_3 = k_1 * k_2^2\\k_3 = 2*10^-^6 * (1*10^3)^2\\k_3 = 2

substituting this using Gibbs law,

\delta G^0_3 = -RT\ln K_3\\\delta G^0_3 < 0

Since K3 is greater than 1, the reaction is thermodynamically favorable.
