The energy of an electron can be change only by set amounts.
The electrons in an energy level of an atom can only move to a higher or lower energy level only if it absorbs or emits a certain amount of energy. If the electron does not have enough energy to move to the next energy level then it will never move.

diamond and graphite are carbon allotropes
and water is water XD
None since CO3 does not exist.
Answer is: sodium bicarbonate is the limiting reagent.
Balanced chemical reaction:
3NaHCO₃(aq) + H₃C₆H₅O₇(aq) → 3CO₂(g) + 3H₂O(l) + Na₃C₆H₅O₇(aq).
n(NaHCO₃) = m(NaHCO₃) ÷ M(NaHCO₃).
n(NaHCO₃) = 1.50 g ÷ 84 g/mol.
n(NaHCO₃) = 0.0178 mol.
n(H₃C₆H₅O₇) = 1.50 g ÷ 192.12 g/mol.
n(H₃C₆H₅O₇) = 0.0078 mol.
From chemical reaction: n(NaHCO₃) : n(H₃C₆H₅O₇) = 3 : 1.
n(NaHCO₃) : 0.0078 mol = 3: 1.
n(NaHCO₃) = 0.0234 mol; amount of substance need to react with citric acid, so we conclude there is no enough sodium bicarbonate.
The answer is D because moving all of the body parts would get the heart racing and the blood pumping!
