Hello!
The balanced chemical equation for the rusting of iron is the following:
4 Fe + 3 O₂ → 2Fe₂O₃
The coefficients to balance the equation are 4,3,2. The fundament of this balance is the Law of Conservation of Mass. This Law states that matter is neither created nor destroyed in a chemical reaction, and in a chemical equation, the moles of each atom is conserved in both sides of the arrow. That means that if 4 Fe atoms are on the left side, 4 Fe atoms should be on the right side.
A suggestion for balancing equations is to start with metal atoms, continuing with non-metals, then hydrogen and lastly oxygen.
Have a nice day!

Answer:
The correct answer is - cellular respiration is when <u><em>chemical</em></u> energy from sugar/glucose is converted to cellular <u><em>energy in the form of ATP</em></u><em><u>.</u></em>
Explanation:
Cellular respiration is a set of metbolic reaction that takes place inside the cell and breaking the sugars or nutrients to convert the chemical energy present in the nutrients into the cellular energy whic is used by cells that is ATP and release water and carbon dioxide as waste.
In this process the ammount of energy store in the cellular currecncy or ATP which is the form of energy that is utilized by the to perform its sunction. The chemical energy that is present in the nutrients or sugar is come from light energy which is stored in the nutrients by photosyntheis process.
