Water (hydrogen oxide) and carbon dioxide
Ethanol is an alcohol. The general formula for alcohols is CnH2n+1OH To know what the value of "n" is, you need to find the number of carbon atoms it has, like this: # 1 CARBON ATOMS: Eth- # 2 CARBON ATOMS: Meth- # 3 CARBON ATOMS: Prop- # 4 CARBON ATOMS: But- # 5 CARBON ATOMS: Pent- # 6 CARBON ATOMS: Hex- # 7 CARBON ATOMS: Hept- # 8 CARBON ATOMS: Oct- ...and so on! plus the terminations of the family of the hyrocarbons it is from: * alkanes: -ane. * alkenes: -ene. * alcohols: -anol. Therefore as ethanol has 2 carbon atoms, its formula would be: C2H5OH
Without a doubt water. All living beings need water for survival as biochemical raections within the cell are carried out in an aqueus medium. The only possible benefit that watering a plant with milk could have would be to provide Caclium; Calcium is required in such small amounts for plant growth that it simply absorbs it from the soil and it is very seldomly (if ever) added as a fertilizer supliment. There is fat, protein and some sugar in milk which is a food source for bacteria and fungi. These spread quickly and may damage the plant.
