Answer 2

The equation that best represents the conservation of matter is:

**6H2O + 6CO2 → C6H12O6 + 6O2**

This equation balances both the number of each type of atom on the reactant side (left) and the product side (right). Specifically, it accounts for:

- 6 carbon atoms (from 6 CO2)
- 12 hydrogen atoms (from 6 H2O)
- 18 oxygen atoms (6 from H2O and 12 from CO2)

On the product side (C6H12O6 + 6O2), you also have:

- 6 carbon atoms (from C6H12O6)
- 12 hydrogen atoms (from C6H12O6)
- 18 oxygen atoms (6 from C6H12O6 and 6 from 6O2)

Therefore, the equation maintains the conservation of matter, as the number of each atom is the same on both sides.

Answer 3

The equation that best represents the conservation of matter is:

**6H2O + 6CO2 → C6H12O6 + 6O2**

This equation is balanced, which means the number of atoms of each element on the reactant side (left) is equal to the number of atoms of each element on the product side (right):

- Reactants:
- **Carbon (C)**: 6 (from 6 CO2)
- **Hydrogen (H)**: 12 (from 6 H2O)
- **Oxygen (O)**: 18 (6 from H2O and 12 from CO2)

- Products:
- **Carbon (C)**: 6 (from C6H12O6)
- **Hydrogen (H)**: 12 (from C6H12O6)
- **Oxygen (O)**: 18 (6 from C6H12O6 and 6 from 6O2)

This confirms that matter is conserved, as all atoms are accounted for in both reactants and products.

The other equations do not balance properly, which means they do not represent the conservation of matter.
