2Al + Fe2O3 ——-> Al2O3 + 2Fe
This is a single displacement reaction
In keeping with the general trends, K-Br will have the smallest bond energy. The bond energy refers to the energy that keeps the atoms in a bond together.
<h3>What is bond energy?</h3>
Bond energy is the energy that is required to hold atoms together in a bond. This energy must also be supplied when the atoms are to be separated.
We have the bond energies of each of the bons in the question, we have to note that the the smallest value of bond energy is Na-Br hence in keeping with the general trends, K-Br will have the smallest bond energy.

Answer:
i am not sure i think they sound the same
Explanation:
Cold air doesn't cause latex helium balloons to deflate, but it does make helium molecules lose energy and move closer together. This decreases the volume inside the balloon and makes the shell of the balloon shrink and sink to the ground.
