A solution of NaOH is standardized by titration with 0.100 N HCL. A total of 10.0 mL of NaOH requires 11.25 mL of HCl . What is the normality of the NaOH solution?
One mole of ideal gas undergoes a three-step process. In step one: the gas expands isothermally and reversibly from state 1 to state 2. In step two: the gas is cooled isochorically yielding state 3.
Calculate the enthalpy change when a 10.0 g of water is heated from 10.0°C to 25.0°C - Calculate the enthalpy change when 10.0 g of water at 100°C is converted to 10.0 g of Vapor at 100°C.
Calculate the lattice energy of RbCl using the following data: Rb(s) => Rb(g) ?H = +86 kJ/mol Rb(g) => Rb+(g) + e- ?H = +409 kJ/mol Cl2(g) => 2Cl(g) ?H = +242 kJ/mol Cl(g) + e- => Cl-(g) ?H = -355 kJ/mol Rb(s) + 1/2 Cl2(g) => RbCl(s) ?H = -435 kJ/..
