Question

An excess of solid iron is reacted with .36g mncl4 according to the following reaction?

Option 1: Single replacement
Option 2: Double replacement
Option 3: Combustion
Option 4: Synthesis

Answer 1

The reaction of solid iron with MnCl4 is a single replacement reaction.

Step-by-step explanation:

The reaction of solid iron with MnCl4 is an example of a single replacement reaction. Single replacement reactions occur when one element replaces another element in a compound. In this case, the iron (Fe) replaces the manganese (Mn) in the compound MnCl4. The balanced chemical equation for this reaction is:

Fe + MnCl4 -> FeCl2 + Mn

Answer 2

The reaction between solid iron and MnCl4 is a single replacement reaction, where iron replaces manganese due to its higher reactivity, leading to oxidation and reduction processes.

The correct answer is option 1: Single replacement.

Step-by-step explanation:

The reaction of an excess of solid iron with .36g MnCl4 is best described as a single replacement reaction. This is because in the provided reactions, we observe that iron (Fe) is reacting directly with the manganese compound and swapping places with the manganese (Mn), suggesting that the iron is replacing the manganese.

Also, examining the provided equations, we can see reduction and oxidation processes where Mn undergoes reduction (from +7 to +2) and Fe undergoes oxidation (from +2 to +3) indicating a redox reaction which often occurs in single replacement reactions.

It is important to note that in an actual single replacement reaction involving iron and MnCl4, Fe would replace Mn because Fe is more reactive than Mn. However, the chlorine would still be a part of the resulting compound in an actual reaction setup.

Since the exact reaction for Fe with MnCl4 is not provided in the material, we can only suggest it as a single replacement based on the behavior exhibited by Fe, Mn, and compounds like MnO4 and Fe3+.

The correct answer is option 1: Single replacement.
