The chemical formula for table sugar is c 12 h 11 o 22 . what can you tell from this formula?

there are 12 electrons in a carbon atom.

the ratio of carbon atoms to hydrogen atoms in a molecule of sugar is 2 to 1.

there are 22 protons in an oxygen atom.

the ratio of oxygen atoms to hydrogen atoms in a molecule of sugar is 2 to 1.

The the last one, but isn't it c6h12o6?

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

Sorry i dont understand the question can you rephase it?
