Sort the chemical equations based on the chemical reactions they represent.

*water → hydrogen + oxygen

*iron + oxygen → iron oxide

*sodium + chlorine → sodium chloride

*sulfur + oxygen → sulfur dioxide

*potassium + chlorine → potassium chloride

*calcium carbonate →calcium oxide + carbon dioxide

The classification would be as follows:

*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.
