Answer:
So if this is about chemical equations. You have 3 steps.
Step 1.- Count each type of atom in reactants and products.
Step 2.- Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.
Step 3.-Repeat steps 1 and 2 until the equation is balanced.
Explanation:
Group 14: Carbon family has valence electrons.
Answer is: iron is oxidized to form rust.
Chemical reaction: Fe + O₂ → Fe₂O₃.
Oxidation half reaction: Fe⁰ → Fe⁺³ + 3e⁻ /×4; 4Fe⁰ → 4Fe⁺³ + 12e⁻.
Reduction half reaction: O₂⁰+ 4e⁻ → 2O⁻²/×3; 3O₂⁰+ 12e⁻ → 6O⁻².
Balanced chemical reaction: 4Fe + 3O₂ → 2Fe₂O₃.
Oxidation is increase of oxidation number, iron is oxidized from oxidation number 0 (Fe) to oxidation number +3 (in rust Fe₂O₃).
in the phase diagram the line between solid and liquid is where both phases available at the same time
I believe it is radishes, hope this helps have a nice day!!! :)))
