This is the equation for the thermite reaction:
1 answer:
The charge of Fe in Fe₂O₃ is +3.
Let's consider the equation for the thermite reaction:
Fe₂O₃ + 2 Al ⇒ Al₂O₃ + 2 Fe
One of the reactants is ferric oxide, we can calculate the charge of Fe in Fe₂O₃ considering that:
- The sum of the charges of the atoms is equal to the charge of the compound.
- The charge of a neutral compound is 0.
- The charge of O in oxides is -2.
The charge of Fe in Fe₂O₃ is:
The charge of Fe in Fe₂O₃ is +3.

Answer - A. Mating Must occur randomly
Reasoning - Since mating must occur randomly are helps with the balance or equilibrium in genetic without any changes within that population since we do not want genetic drift, mutation and especially do not want any foreign or different species mating with the species we are targeting. So A is your best answer.
