Using standard reduction potentials from the ALEKS Data tab, calculate the standard reaction free energy Agº for the following redox reaction. Round your answer to 3 significant digits. 2 MnO2 (s) +80H- (aq) +3Br2 (1) > 2Mno4-, (aq) +4H20 (1) +6Br- (aq)?

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
