[6] The first atomic explosion was detonated in the desert north of Alamogordo, New Mexico, on July 16, 1945. What fraction of Strontium-90 (t1/2 = 28.8 years) originally produced by the explosion still remains as of July 16, 2022?
[7] Use Hess's Law of Heat Summation to find the enthalpy of this reaction: H(g) + Br(g) → HBr(g) You are given the following data: H2(g) → 2H(g); AH° -436.4 kJ/mol Br:(8) 2Br(g): AH° = 192.5 kJ/mol H2(g) + Br2(g) 2HBr(g): AH°-72.4 kJ/mol
