To determine which equation best represents the conservation of matter, we need to ensure that the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side.
Let's analyze the first equation, which appears to be the most straightforward in terms of stoichiometry:
Equation: 3H2O + 3CO2 → C6H12O6 + 6O2
Counting Atoms:
-
Reactants:
- H: 3 (from 3H2O) * 2 = 6
- O: 3 (from 3H2O) * 1 + 3 (from 3CO2) * 2 = 3 + 6 = 9
- C: 3 (from 3CO2)
-
Products:
- H: C6H12O6 → 12
- O: C6H12O6 → 6, and 6 (from 6O2) * 2 = 12
- C: C6H12O6 → 6
Since this equation is not balanced for both reactants and products (the number of hydrogens and oxygens don’t match), let's check the balance for the other options.
After analyzing all options in detail, I conclude that the correct equation that represents conservation of matter is:
6H2O + 6CO2 → C6H12O6 + 6O2
In this equation:
- The total number of atoms before and after the reaction is equal, which respects the law of conservation of matter.
So, none of the options you provided seem to accurately reflect a balanced reaction that demonstrates conservation of matter. The correct representation points out that matter can neither be created nor destroyed in a closed system. You may want to check the equations again for mistakes or the proper symbol combination that satisfies the conservation principle.
