3H2O+3CO2→C6H12O6+6O2
3 H sub 2 O plus 3 C O sub 2 rightarrow C sub 6 H sub 12 O sub 6 plus 6 O sub 2
6H2O+6CO2→C6H12O6+6O2
6 H sub 2 O plus 6 C O sub 2 to C sub 6 H sub 12 O sub 6 plus 6 O sub 2
6H2O+6CO2→C3H6O3+3O2
6 H sub 2 O plus 6 C O sub 2 rightarrow C sub 3 H sub 6 O sub 3 plus 3 O sub 2
6H2O+10CO2→C6H12O6+4O2

Answer 1

The equation that best represents the conservation of matter is one where the number and type of atoms in the reactants are equal to the number and type of atoms in the products.

Among the equations listed, the one that accurately represents this principle is:

6H2O + 6CO2 → C6H12O6 + 6O2

Here, on both sides of the equation, you have a total of 6 carbon atoms, 12 hydrogen atoms, and 18 oxygen atoms, thus satisfying the conservation of matter.

The equivalent written form with subscripts is:

6 H₂O + 6 CO₂ → C₆H₁₂O₆ + 6 O₂

This shows that all atoms are accounted for in the reaction, making it the correct representation for the conservation of matter.
