Answer 2

The reaction you've written is the decomposition of water (H2O) into hydrogen gas (H2) and oxygen gas (O2). The □H symbol represents the change in enthalpy, and □H>0 indicates that this reaction is endothermic, meaning it absorbs heat from the surroundings.

In an endothermic reaction like this one, energy is required to break the bonds in the reactants (H2O) and form the bonds in the products (H2 and O2). The energy absorbed from the surroundings is typically in the form of heat.

Overall, this reaction requires an input of energy to proceed, and it is not spontaneous under standard conditions. Heat or some external energy source must be provided to initiate and sustain the reaction.
