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

One hundred liters of methyl methacrylate containing 10.2 moles of an initiator (t1 / 2 = 50 h)in solution it polymerizes at 60°C. Calculate the amount of polymer formed in the first hourreaction. [Data: monomer density 0.94 g / cm3; kp = 515 L / mol * s; kt = 2.55x10^7 L / mol * s; f = 0.3].

3. Make an energy diagram for the heat formation of one mole of each of the following substances: b. H₂(g) + 12(9) 2H₂(g) + CO(g) C(s) + 2H₂ (9) → 2H(a) →→→→ CH₂OH → CH4(0)
