Answer:
See notes on LeChatlier's Principle I gave you yesterday.
Explanation:
Remember chemical see-saw => Removing Fe⁺³ makes the reactant side of the see-saw lighter causing the balance to tilt right then shift left to establish a new equilibrium with new concentration values. Such would result in a decrease in FeSCN⁺² concentration and increases in Fe⁺³ and SCN⁻ concentrations to replace the original amount of ppt'd Fe⁺³. => Answer Choice 'B' ... Also, see attached => Concentration effects on stability of chemical equilibrium .
Answer:
The answer to your question is below
Explanation:
Organic chemistry studies the compounds that have carbon, hydrogen, oxygen and other elements in their structure.
Carbohydrates are biomolecules that are composed of carbon, hydrogen, and oxygen that is why they are studied by organic chemistry.
Other biomolecules that are also studied by organic chemistry are Proteins, Lipids, and Vitamins.
<u>Answer:</u> The chemical symbol of the compound formed is 
or 
<u>Explanation:</u>
An ionic compound is formed when the complete transfer of electrons takes place from one element (usually metals) to another element (usually non-metals).
The element losing electron (metal) forms a positive ion known as a cation while the element gaining electron (non-metal) forms a negative ion known as an anion.
Element X has the atomic number 11 which is sodium. The electronic configuration of it is 
This element will lose 1 electron to form 
ion of 
Chlorine has the atomic number 17. The electronic configuration of it is 
This element will gain 1 electron to form 
ion
When these two ions combine, they lead to the formation of an ionic compound having a chemical formula of or
Hence, the chemical symbol of the compound formed is or
The balanced equation is 4Fe(s) + 3O2(g) -> 2Fe2O3(s). For the oxygen, its oxidation state in O2 is 0 and in Fe2O3 is -2. So the oxidation state change from 0 to -2.
