Question

question 12: the periodic table of elements is shown. respiration is the reverse of photosynthesis. people use oxygen and glucose from plants to produce carbon dioxide and energy. how many different atoms can be identified in the chemical reaction for respiration? c₆h₁₂o₆ + 6o₂ → 6co₂ + 6h₂o + energy

Explanation:

Step1: Identify elements in reactants

In $C_{6}H_{12}O_{6}+6O_{2}$, elements are carbon (C), hydrogen (H), oxygen (O).

Step2: Identify elements in products

In $6CO_{2}+6H_{2}O$, elements are carbon (C), hydrogen (H), oxygen (O).
