- This thermodynamic cycle describes the formation of an ionic compound MX2 from a metal element M and nonmetal element X in their standard states. What is the lattice enthalpy of MX2 ? What is the enthalpy formation of MX2 ? Suppose both the heat of sublimation of M and the ionization enthalpy of M were smaller. Would MX2 be more stable? Or less? or impossible to tell without more information?arrow_forward7. Draw the mechanism to describe the following transformation: Note: This is a base catalyzed reaction.

QUESTION Liquid A is known to have a lower viscosity and lower surface tension than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment Liquid A and Liquid B are each pumped through tubes with an inside diameter of 27.0 mm, and the pressures PA and PB needed to produce a steady flow of 2.4 mL/s are measured. 25.0 mL of Liquid A are poured into a beaker, and 25.0 mL of Liquid B are poured into an identical beaker. Stirrers in each beaker are connected to motors, and the forces FA and FB needed to stir each liquid at a constant rate are measured. predicted outcome OPA will be greater than PB OPA will be less than PB OPA will be equal to PB It's impossible to predict whether PA or PB will be greater without more information.…arrow_forwardShow work.
