Which statement about the following reaction is true? 4 Fe + 3 O2 --.> 2 Fe2O3
The reaction is not balanced.
Four grams of Fe reacts with 3 grams of O2 to form 2 grams of Fe2O3.
Fe2O3 is the reactant in this reaction.
Four atoms of Fe react with 3 molecules of O2 to form 2 molecules of Fe2O3
None of the above.
The answer is :
Four atoms of Fe react with 3 molecules of O2 to form 2 molecules of Fe2O3. You identified the reactants as Fe and O and the product as Fe2O3. You also knew that the coefficients in the equation correspond to the number of atoms or molecules that take part in the reaction
