using Le Chanteliers principle what will happen and why when NaOH is introduced into iron(III) thicyanate ion equilibrium system
1 answer:
Answer:
- <u>More </u><u>[FeSCN]²⁺ </u><u>will be consumed shifting the reaction to the left.</u>
Explanation:
Th <em>equilibrium </em>equation for <em>iron(III) thiocyanate ion </em>is:
Fe³⁺ + SCN⁻ ⇄ [FeSCN]²⁺
When<em> NaOH is introduced into the equilibrium system, </em>part of the OH⁻ ions react with the Fe³⁺ ions in solution, as per the chemical equation:
Fe³⁺ + 3OH⁻ ⇄ Fe(OH)₃ ↓ (solid precipitate)
Threfore, the concentration of Fe³⁺ ions in solution decreases.

First, you need to have a periodic table that contains the electronegativities values. once you have them, you just need to subtract the values of the atoms and each bond. I have attached a table with these values. also, it does not matter then order in which you subtract them because they are always positive values. even though you get negative values in your calculator, just make it positive.
H-S----> 2.1 - 2.5= 0.4
H-Cl---> 2.1 -3.0=0.9
H-O---> 2.1- 3.5= 1.4
H-F----> 2.1 - 4.0= 1.9
HF is the most polar because it has the highest electronegativity difference.

Answer and Explanation:
DIFFERENCE BETWEEN ELEMENT AND COMPOUND :
- An element is made up of same type of atoms whereas a compound is made up of different type of atoms.
- A compound can be separated by chemical methods but an element can not be separated by chemical methods.
- Example of element is Cu Fe C and example of compound is
etc
- Elements can not be split into different substances but compound can be splited into different substances
