The example of two systems that are separated by a wall and are thermally but not chemically in equilibrium with each other needs to be explained. Concept Introduction: Thermodynamics is the branch of chemistry that deals with heat exchange between system and surroundings. The thermodynamic process can be classified in two types; isothermal and adiabatic process. An isothermal process occurs at constant temperature between system and surroundings. On the contrary, adiabatic processes do not allow the transfer of heat.

Public water systems often add fluoride to drinking water because, in the proper amounts, fluoride improves dental health and prevents cavities. Too much fluoride, however, can cause fluorosis, which stains teeth. In 2015, the U.S. Public Health Service (PHS) revised its 1962 recommenda- tions for the amount of fluoride in public water systems. The 1962 recommendations depended on the average temperature for the region in question as shown here. because U.S. citizens are now getting fluoride from other sources, including toothpaste and mouthwash. The rec- ommended level balances the need for fluoride to im- prove dental health with the risk of developing fluorosis from too much fluoride. Examine the data in the table and answer the following questions: (a) Determine the percent change in optimum recom- mended fluoride concentration for a water system with annual average maximum daily temperatures of 17.8–21.4 °C. Hint: the percent change is given by 1962 Fluoride Recommendations final…

Hydrates are ionic compounds that contain water molecules that are incorporated into the structure of the ionic compounds in a specific ratio. For example, barium chloride dihydrate has the chemical formula BaCl, 2H20 in which the two water molecules are incorporated into every unit of BaCl, ionic compound. In this experiment you will determine what are the final products that are obtained from heating of BaCl, 2H,0. Depending on the extent of heating, three different sets of products are predicted as listed below: + H2O(g) Reaction 1 BaCl, 2H,O(s) heat BaCl,H,O(s) 2H20(9) Reaction 2 heat BaCl, 2H,O(s) BaClae) + heat BaO(s) H2Og) 2HCI (9) Reaction 3 + BaCl, 2H,O(s) QUESTION If the mass of BaCl, 2H,O(s) sample subject to thermal decomposition was 2.526 g, what is the theoretical yield of BaClis) if Reaction 2 occurred. (The molar mass of BaCl, 2H,Os, is 244.2 g; the molar mass of BaCl2(s) is 208.2 g)
