Revise your earlier explanation for this question based on what you now know about valence electrons, chemical reactions, and full outer shells of electrons: Hydrogen has one electron, helium has two electrons, and lithium has three electrons. Hydrogen and lithium are both reactive, but helium is nonreactive. How can electrons be used to explain this pattern of behavior?

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

the equation for synthesis of water is as follows;

here two moles of hydrogen are used with one mole of oxygen which gives one molecule of water as a product. but shana misinterpreted 2 moles as 2 grams in this equation.
