발열 반응

: 반응물의 에너지 준위 > 생성물의 에너지 준위

답: 생성물인 물(water)

This reaction is violent,

meaning a significant amount of energy is released.

This means that the products of the reaction (water)

have a lower potential energy than the reactants.

In an exothermic reaction like this,

the products are lower in potential energy

than the reactants.

So, the final answer is:

The mixture of hydrogen and oxygen gases

is higher in energy than water.

This is because the reaction is exothermic,

meaning energy is released during the reaction,

lowering the potential energy of the products (water).

This can be represented in an energy-level diagram,

where the reactants are at a higher energy level

than the products.
