artis aal i. Based on Textbook 2.35-2.37: Orthopedic surgeons use bone “cement" to set 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 you. free radical CH3 c=c CH3 +CH;-C c=0 H vinyl polymerization C=0 CH3 CH3
