6. Which scientific law is best demonstrated by the reaction shown in the diagram? 2H2 + O2-2H20
Hydrogen Oxygen Water
ALA
law of universal gravitation
law of angular momentum
law of conservation of energy
law of conservation of mass

law of conservation of mass

Explanation:

According to the law of conservation of mass, mass is neither created nor destroyed.

This is actually the law that guides the balancing of chemical reaction equations.

On the left side we have four atoms of hydrogen and two atoms of oxygen. Exactly the same number of atoms of each element is seen on the right hand side in accordance with the law of conservation of mass.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
