Answer:
Atomic Particles
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge).
In the given chemical reaction iron is less electropositive metal and aluminum is more electropositive and behave as a reducing agent also.
<h3>What is electropositivity?</h3>
Electropositivity is the ability of an atom of donation or losing of electrons easily.
From the given chemical reaction it is clear that oxidation state of iron changes from +3 to 0 & of aluminum is from 0 to +3. So in the above chemical reaction aluminum is more electropositive than iron metal. And aluminum is behave as a reducing agent as it helps in the reduction process by providing electrons.
Hence aluminum is electropositive metal and reducing agent, iron is less electropositive.

It is given that the price of the carpet is $ 28.99 per square yard
Step 1: Convert square yard to square meter
1 square yard = 0.836 square meter
Step 2: Calculate the cost/square meter
Now based on the relation in step (1) we can write
0.836 square meter of carpet costs $ 28.99
Therefore the cost of 1 square meter of the carpet would be
= $ 28.99 * 1 sq meter/0.836 sq meter
= $ 34.68
