Final answer:
Statement 1 and statement 2 are true, while statement 3 is false.
Step-by-step explanation:
The statement 1 is true because there is the same number of Hydrogen atoms in the reactant side as there are in the product side. The statement 2 is true because the reactants are 2 molecules of water and 1 molecule of oxygen. The statement 3 is false because new atoms are not formed by destroying the atoms in the reactants, but rather by rearranging the atoms in the reactants to form new molecules.
