The classification would be as follows:

<span>*water → hydrogen + oxygen  =   decomposition
*iron + oxygen → iron oxide    =    synthesis
*sodium + chlorine → sodium chloride        =       synthesis
*sulfur + oxygen → sulfur dioxide              =      synthesis
*potassium + chlorine → potassium chloride        =    synthesis
*calcium carbonate →calcium oxide + carbon dioxide       = decomposition

Hope this answers the question. Have a nice day.</span>

Decomposition reactions are said to be those reactions in which a reactants breakdown into two or more products. The general reaction for decomposition reactions is as follow,

                                         ABC    →    A  +  B  +  C

Specific Examples are as,

                                Water    →     Hydrogen + Oxygen

                                2 H₂O    →           2 H₂     +      O₂

               Calcium carbonate    →     Calcium oxide + Carbon dioxide

                            CaCO₃              →              CaO         +        CO₂

While, Synthetic reactions are said to be those reactions in which two or more reactants combine to form two or more products. The general reaction for synthetic reactions is as follow,

                                         A  +  B  +  C    →    ABC

Specific Examples are as,

                                  Iron + Oxygen     →     Iron Oxide

                                    2 Fe  +  3 O₂      →        2 Fe₂O₃

                          Sodium + Chlorine     →     Sodium chloride

                              2 Na  +       Cl₂        →            2 NaCl

                            Sulfur + Oxygen      →      Sulfur dioxide

                                  S    +    O₂            →             SO₂

                   Potassium + Chlorine      →      Potassium chloride

                            2 K     +     Cl₂            →              2 KCl

What is the main reason water from the ocean turns to water vapor , and then evaporates into the air
melamori03 [73]

Hello! :)

C) heat from the sun

Why?

Because the sun’s heat makes the water turn to steam—or what we call “water vapor.”

Hope this helped and I hope I answered in time!

Good luck!
