Final answer:
A balanced chemical equation that includes 6 atoms of oxygen is the formation of sulfur trioxide from sulfur dioxide and oxygen, represented as 2SO2 + O2 → 2SO3.
Step-by-step explanation:
The student is asking about a balanced chemical equation that involves exactly 6 atoms of oxygen. An example of such a reaction is the formation of sulfur trioxide from sulfur dioxide and oxygen, which can be represented by the balanced equation:
2SO2 + O2 → 2SO3
This equation illustrates a redox reaction where both sulfur and oxygen are balanced, with 2 sulfur atoms and 6 oxygen atoms present on each side of the equation.
The balancing of equations is a fundamental concept in stoichiometry, which deals with the quantitative relationships between reactants and products in a chemical reaction.
