If black balls are carbon atoms and white balls are hydrogen atoms then the given structure is of PROPANE
(Make sure to mention what exactly balls are?)
<span>Potassium sorbate is the potassium salt of sorbic acid. It is comprised of carbon, hydrogen, oxygen and potassium. Put differently, its chemical formula is: CH3CH=CH−CH=CH−CO2K. Potassium sorbate is significantly more stable than plain potassium, and it is often used to preserve food.</span>
1.) K, N, and O
2.) Fe and O are unbalanced
3.) a
4.) Its already balanced
5.) I belive it is 2Cr+Cl2 -> CrCl3
Probably off the west coast of North America.
Answer: Valence electrons are involved in a chemical reaction.
Explanation:
A chemical reaction takes place when there is an involvement of valence electrons. Bond formation involves either sharing of valence electrons or transfer of valence electrons. Bond breaking involves the separation of valence electrons.
When valence electrons are shared between the atoms, it leads to the formation of covalent bond.
When transfer of electrons takes place from one atom to another atom, it leads to the formation of ionic bond.
Hence, valence electrons are involved in a chemical reaction.
