Answer:
An atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed.
Answer:
3.7 mol O₃
Explanation:
Step 1: Write the balanced equation
2 O₃ ⇒ 3 O₂
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of O₃ to O₂ is 2:3.
Step 3: Calculate the number of moles of O₃ required to produce 5.5 moles of O₂
We will use the previously established molar ratio.
5.5 mol O₂ × 2 mol O₃/3 mol O₂ = 3.7 mol O₃
