The molecular structure of water contains two atoms of hydrogen and one atom of oxygen. when water reaches its boiling point and turns into water vapor, what happens to its molecular structure? a) it remains the same b) it changes the ratio of atoms c) it forms bigger molecules d) it forms lighter molecules

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.

diaria maybe go see a doctor about that
