With respect to 1 kg of liquid water: (a) Initially at 0 °C, it is heated to 100 °C by contact with a heat reservoir at 100 °C. What is the entropy change of the water? Of the heat reservoir? What is ΔStotal? (b) Initially at 0 °C, it is first heated to 50 °C by contact with a heat reservoir at 50 °C and then to 100 °C by contact with a reservoir at 100 °C. What is ΔStotal? (c) Explain how the water might be heated from 0 °C to 100 °C so that ΔStotal = 0.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

∠gdh and ∠edh on edg.

answer is c
