Acid-base reactions form water. 8) Combustion reactions always result in the formation of water. What other types of chemical reaction may result in the formation of water? Write examples of these reactions on the opposite side of this paper. Acid-base: HCl + NaOH H2O + NaCl Synthesis: 2 H2 + O2 2 H2O Decomposition: NH4OH NH3 + H2O Single displacement: H2 + 2 NaOH 2 Na + 2 H2O (not common) For chemistry help, visit www.chemfiesta.com © 2001 Cavalcade Publishing All Rights Reserved...
