Ethanol molecule (C2H5OH) What BONDS are found in these materials? Water molecule (H2O) BONDS FOUND IN EACH MOLECULE: Water: H-O Ethanol: H-O, C-O, C-H, C-C Wood: H-O, C-O, C-H, C-C Ethanol molecule (C2H5OH) Cellulose (C6H10O5)n Photo Credit: Craig Douglas, Michigan State University

What BONDS are found in these materials? Water molecule (H2O) Chemical Energy Energy found in the bonds of molecules. C-C and C-H bonds means molecules have available chemical energy. So which materials have available chemical energy? Ethanol molecule (C2H5OH) Cellulose (C6H10O5)n Photo Credit: Craig Douglas, Michigan State University
