Calculate the enthalpy change associated with the conversion of 25.0 grams of ice at -4.00°C to water vapor at 110.0°C. The specific heats of ice, water, and steam are 2.09 J/g-K, 4.18 J/g-K, and 1.84 J/g-K, respectively. For H2O, Hfus = 6.01 kJ/mol and Hvap = 40.67 kJ/mol.
12.00mL of 0.125M of HCl is required to titrate 21.55mL of Mg(OH)2. Calculate the molarity of the unknown base.
Choose the stronger of each pair of acids, respectively, and explain why: a) HBrO3 or HBrO b) HBrO2 or HIO2 A. a) HBrO because Br has a lower oxidation state (fewer number of O atoms around it) in HBrO than in HBrO3
