Calculate the total amount of energy, in kJ for the reaction at the top.  Round to the nearest tenth of kJ.

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

Consider the following reaction: 2 Mg + O22 MgO AH xn=-1203 kJ Calculate the amount of heat (in kJ) associated with complete reaction of 97.2 grams of Mg. O-3862 kJ O-4812 kJ O-601.5 kJ -2406 kJ O-1203 kJ 13

The reaction below has a change in enthalpy of -1203kJ. What amount of heat is associated with the complete combustion of 4.000moles of magnesium? 2Mg + 02->2MgO O-1203kJ O-2406kJ O-601.5kJ O-4812kJ

Chloroform is an organic solvent found in many chemistry laboratories, and it is fairly volatile. The density of the vapor at a pressure of 220 mm Hg and 25 oC is 1.42 g/ L. Calculate the molar mass of chloroform; show all work.

Ammonia is made from nitrogen and hydrogen. The enthalpy change in the reaction is -92 kJ/mole. The reaction is reversible and reaches equilibrium   Write the equation for the reaction

Consider the reaction. 2 Fe,O, 4 Fe + 30, AHn = +824.2 kJ The formation of 84.0 g of Fe results in the absorption of 3.10 x 102 kJ of heat. the absorption of 17300 kJ heat. the absorption of 1240 kJ of heat. the release of 1240 kJ of heat. the release of 3.10 x 10² kJ of heat. the release of 17300 kJ of heat.
