Based on Textbook 2.35-2.37: Orthopedic surgeons use bone “cement" to set al i. artificial hip implants in place. This “cement" is methyl methacrylate that is polymerized during the surgery. However, surgeons notice a substantial amount of heat evolution from the reaction. Calculate the reaction energy if a surgeon uses 20g of methyl methacrylate glue (the precursor) to set a given hip implant. The polymerization reaction is given for ar you. free radical H CH3 CH3 +CH;-C C=0 vinyl polymerization H c=0 o CH3 CH3
