(a) What are the signs of \(\Delta S\) and \(\Delta H\) for the process depicted here?
(b) If energy can flow in and out of the system to maintain a constant temperature during the process, what can you say about the entropy change of the surroundings as a result of this process? [Sections 19.2 and 19.5]

Antavia Tinker BIO 101 Royster 9.18.2018 Introduction to Acids & Bases: A Web Quest 1. http://www.visionlearning.com/library/module_viewer.phpc3=&mid=58&l= The word acid comes from the Latin word acere meaning sour. Boyle stated that acids taste sour, are corrosive to metals, change the color of litmus to red, and become less acidic when mixed with bases. He described bases as feeling slippery, changing litmus to the color blue, and becoming less basic when mixed with an acid. About 200 years later, Arrhenius proposed that water can dissolve many compounds by separating them into their individual ions. He suggested that acids contain hydrogen and can dissolve in water to release hydrogen ions. Bases dissolve in water to release hydroxide ions into the solution. 2. http://www.chem4kids.com/files/react_acidbase.html Every liquid has acidic& basic traits. One exception might be H2O. It is just water. However, the positive ions and negative ions cancel each other out. 3. http://chemistry.about.com/od/acidsbases/a/acidbaseformula.htm Give the formula for the following acids: Hydrofluoric AcidHF Hydrochloric AcidHCl Hydro sulfuric AcidH S 2 Nitric AcidHNO 3 Sulfuric AcidH2 OS 4 Acetic AcidHC H 2 3 2 Boric AcidH B3 3 Give the formula for the following bases: Sodium HydroxideNaOH Potassium HydroxideKOH Calcium HydroxideCa(OH )2 Iron (II) HydroxideFe(OH
