The following chemical equation is not balanced: Al + CuO Al2O3 + Cu When this chemical equation is correctly balanced, what is
2 answers:
<u>Answer:</u> The coefficient of copper is 3.
<u>Explanation:</u>
Every balanced chemical equation follows law of conservation of mass.
This law states that mass can neither be created nor be destroyed, but it can only be transformed from one form to another form. This also means that total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.
The given balanced chemical equation follows:
By Stoichiometry of the reaction:
2 moles of aluminium reacts with 3 moles of copper oxide to produce 1 mole of aluminium oxide and 3 moles of copper.
Hence, the coefficient of copper is 3.

Explanation:
When we talk about electrophilic substitution, we are talking about a substitution reaction in which the attacking agent is an electrophile. The electrophile attacks an electron rich area of a compound during the reaction.
The five membered furan ring is aromatic just as benzene. This aromatic structure is maintained during electrophilic substitution reaction. The attack of the electrophile generates a resonance stabilized intermediate whose canonical structures have been shown in the image attached.
