Answer:
The correct answer is a hypothesis.
It depends on the direction of the arrow.
If the arrow goes like this ---> the reactant would be 2Fe2O3
If the arrow goes like this <--- the reactants would be 4Fe + 3O2
The best set of reagents to achieve the ph-co2h => ph-come will be Br2, CH2N2.
A material or ingredient supplied to a system to trigger a chemical reaction or check to see whether one occurs is known as a reagent as well as an analytical reagent. Reactant refers to a substance that is consumed during a chemical reaction. The phrases reactant and reagent just aren't frequently used interchangeably.
Diazomethane reacts swiftly and extremely effectively, producing just N2 as a byproduct, making it an appealing methylating agent for carboxylic acids including phenols.
Therefore, the best set of reagents to achieve the ph-co2h => ph-come will be Br2, CH2N2.
