enthalpy of formation of sodium chloride. The enthalpy change when one mole of a NaCl is formed from its elements under standard conditions. They are exothermic because new bonds are being made between the atoms of the elements sodium and chlorine. Na(s) + ½ Cl2 (g) NaCl(s) ∆Hf° (NaCl) = - 411 kJmol-1 ∆H1° standard enthalpy of atomization of chlorine. The energy required to change one mole of gaseous chlorine molecules into one mole of gaseous chlorine atoms. Endothermic because the

abundance of scientific information. Even though most people consider it a very good book‚ including me‚ if you stop and look you’ll discover that just about all the book achieves‚ from a literary standpoint‚ is telling an interesting story (novelguide.com NA). Crichton was born in Chicago in 1942 and was raised in Long Island (Chapman 67). With a B.A. in anthropology‚ Crichton was pursuing a career in medicine‚ which may have influenced his chosen genre. To help pay for college‚ he wrote books under many

the different colony count observed. Materials and Methods Initially‚ two plates were gathered one was nutrient agar (NA) and the other was sabouraud dextrose agar (SDA). Then gathered two packs of cotton tipped applicators. Then a magic marker was used to label each plate making quadrants numbering each one. Also the name and date was written on the edge of the plate. In the NA plate Whitney swabbed her left index finger in the first quadrant. Then washed her hands. In the second quadrant Whitney

was _______ mV. 3. True or False: For most neurons‚ the concentration of Na+ and K+ ions inside and outside the cell are the primary factors that determine the resting membrane potential. 4. Explain why increasing the extracellular K+ causes the membrane potential to change to a less negative value. 5. Discuss the relative permeability of the membrane to Na+ and to K+ in a resting neuron. 6. Discuss how a change in Na+ or K+ conductance would affect the resting membrane potential. ACTIVITY

Gives best results when 1o alkyl halides are used. Mechanism is SN2. Alkoxides may be prepared by reacting an alcohol with NaH or by reacting an alcohol with Na metal. Phenoxides may be prepared by reaction of phenols with NaOH ROH + NaH ROH + Na ArOH + NaOH RO Na - - +

The CULTURE OF BAHALA NA Of the 1‚000 entries from the Internet‚ the first meaning of “Bahala na” that I was able to extract is “Come/Happen what may” or “Whatever will be will be.” Let us analyze a song composed by Heber Bartolome (2001) entitled “Bahala Na.” (The translation into English on the right column.) The song captures the Bahala na attitude of the Filipino. A Filipina worker goes abroad to seek greener pastures and
