From the chemical equation given, one mole of CH4 yields two moles of water (H2O). If all the methane gas that is 8.9 L is combusted then the volume of water produced is the number of moles H2O times the volume of the methane gas used up, that is 8.9 L × 2 = 17.8 L of water produced.

Answer:
No it will not have the same chemical properties as the initial substance.
Explanation:
In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants
Yes it is due to refraction of light in water
