Hydrogen gas can combine with oxygen gas under certain conditions to form water.
which name is a general term for water in this reaction?
product
ionic compound
reactant
isotope

The correct answer is product.

Explanation:

Hydrogen gas reacts with oxygen gas to generate water molecule.

   2H2+O2 = 2H2O

We all know that that substances which are present at the left hand side of the equilibrium sign act as substrate and the substances those are present in the right hand side of the equilibrium sign are called products.

  From that point of view it can be stated that water or H2O is the product of the reaction between hydrogen and oxygen.

"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."
