Question

Which of the following statements are correct for the thermite reaction.

Check all that apply.
O The internal energy of the reactants is more than the internal energy of the products.
O The thermite reaction is endothermic.
O Heat is absorbed from the surroundings.
O The enthalpy change for the system is negative.
O The internal energy of the system decreases.

Answer 1

Answer:1,4,5

Step-by-step explanation:

Answer 2

The correct options are: 1, 4, and 5

Step-by-step explanation:

Thermite reaction: It is defined as the chemical reaction where a metal oxide is replaced by the another molten metal which is more reactive in nature compare to the metal which is present in the metal oxide, and releasing a lot of heat.

Reduction of a metal oxide to synthesize a metal with the help of using aluminum powder which is functioning as a reducing agent is known as Thermite Reaction, and it is highly exothermic in nature. So, the correct options are:

1) The internal energy of the metal (reactant) is more than the internal energy of the products.

4) The enthalpy change for the system is negative.

5) The internal energy of the system decreases.
