Answer:
It reacts with metals to form metal hydroxide and hydrogen gas. it s an chemical property and it decomposes to H2 and O2 is also another chemical property property. because in these reaction H2O has changed to something else hence are called chemical property.
Explanation:
Water, H₂O, will have the highest melting point.
Explanation:
So here we have listed the hydrides of oxygen, sulphur, selenium and tellurium.
From this elements oxygen have the highest electronegativity and as a consequence the oxigen hydride (water, hydrogen dioxide) it is able to form hydrogen bonds between molecules. So you need more energy to overcome the interactions between molecules in water that for the other compounds.
Water, H₂O, will have the highest melting point between the listed hydrides.

An ionic bond is composed of a cation and anion, which are charged ions. You cannot have atoms with ionic bonds, because there is no opposite attraction between charges due to atoms having a net nuclear charge of zero. Therefore, a cation and anion would most likely be joined by an ionic bond.
There is a difference in the time we see things from space. There is a delay so we see things after they happen
