After completion of this reaction, a metal is obtained in the molten state. Identify the metal.

Options

A. Copper
B. Sodium
C. Iron
D. Silver

Answer

To solve the question regarding the thermite reaction and identify the metal obtained in the molten state, we can follow these steps:

### Step 1: Understand the Thermite Reaction
The thermite reaction is a type of exothermic reaction where a more reactive metal displaces a less reactive metal from its oxide. This reaction typically involves a metal oxide and a more reactive metal.

### Step 2: Identify the Components of the Reaction
In the case of the thermite reaction involving iron, the metal oxide used is iron(III) oxide (Fe2O3), and the more reactive metal used is aluminum (Al).

### Step 3: Write the Chemical Equation
The reaction can be represented by the following chemical equation:
\[ Fe_2O_3 + 2Al \rightarrow 2Fe + Al_2O_3 \]
In this reaction, aluminum displaces iron from iron(III) oxide, forming aluminum oxide (Al2O3) and releasing iron.

### Step 4: Determine the State of the Products
During the reaction, the iron produced is in a molten state due to the high temperature generated by the exothermic nature of the reaction. This means that the iron is not solid but rather in liquid form.

### Step 5: Identify the Metal Obtained
From the reaction, we can see that the metal obtained in the molten state is iron (Fe).

### Final Answer
The metal obtained in the molten state after the completion of the thermite reaction is **iron (Fe)**.
