If you find that [CoCl42-(aq)] = 0.783 M, [Co(H2O)62+(aq)] = 0.569 M, and [Cl-(aq)] = 0.495 M at 6 ∘C, what is value of ΔG at 6 ∘C, in kJ/mol? Express your response to two digits after the decimal.
Resubmitting this question for the third time because it keeps getting denied. Can someone help me solve part K. I got -3.1J for part K and its wrong. NO I can NOT give you the book values for standard S because they are WRONG. I'm hoping that who ever answers this has their OWN list of standard S values.
What is the value of Kw for a sample of pure water at room temperature?

Mr. Roy, the principal of a reputed school organized a seminar in which he invited parents and principals to discuss the serious issue of diabetes and depression in students. They all resolved this issue by strictly banning the junk food in schools and to introduce healthy snacks and drinks’like soup, lassi, milk, etc. in school canteens. They also decided to make compulsory half an hour physical activities for the students in the morning assembly daily. After six months, Mr. Roy conducted the health survey in most of the schools and discovered a tremendous improvement in the health of students. After reading the above passage, answer the following: What are the values (at least two) displayed by Mr. Roy? As a student, how can you spread awareness about this issue? What are tranquilizers? Give an example. Why is the use of aspartame limited to cold foods and drinks?
In the 1880s, Frederick Trouton noted that the enthalpy of vaporization of 1 mol pure liquid is approximately 88 times the boiling point, Tb, of the liquid on the Kelvin scale. This relationship is called Troutons rule and is represented by the thermochemical equation liquid gas H = 88 Tb, joules Combined with an empirical formula from chemical analysis, Troutons rule can be used to find the molecular formula of a compound, as illustrated here. A compound that contains only carbon and hydrogen is 85.6% C and 14.4% H. Its enthalpy of vaporization is 389 J/g, and it boils at a temperature of 322 K. (a) What is the empirical formula of this compound? (b) Use Troutons rule to calculate the approximate enthalpy or vaporization or one mole of the compound. Combine the enthalpy of vaporization per mole with that same quantity per gram to obtain an approximate molar mass of the compound. (c) Use the results of parts (a) and (b) to find the molecular formula of this compound. Remember that the molecular mass must be exactly a whole-number multiple of the empirical formula mass, so considerable rounding may be needed.
On the occasion of World Health Day, Dr. Satpal organized a ‘health camp’ for the poor farmers living in a nearby village. After check-up, he was shocked to see that most of the farmers suffered from cancer due to regular exposure to pesticides and many were diabetic. They distributed free medicines to them. Dr. Satpal immediately reported the matter to the National Human Rights Commission (NHRC). On the suggestions of NHRC, the government decided to provide medical care, financial assistance, setting up of superspeciality hospitals for treatment and prevention of the deadly disease in the affected villages all over India. (i) Write the values shown by (a) Dr. Satpal (b) NHRC. (ii) What type of analgesics are chiefly used for the relief of pain of terminal cancer? (iii) Give an example of artificial sweetener that could have been recommended to diabetic patients.

A 51−kg person drinks 4.6 × 102 g of milk, which has a caloric value of approximately 3.0 kJ/g. If only 17 percent of the energy in milk is converted to mechanical work, how high (in meters) can the person climb based on this energy intake? Enter your answer in scientific notation.Hint: The work done in ascending is given by mgh, where m is the mass (in kg), g is the gravitational acceleration (9.8 m/s2), and h is the height (in meters).
