You and your team work at a scientific research facility that is working towards creating the newest and best batteries for cell phones. Last week, you were told you have a new boss. Your new boss has a science background but he hears that beryllium (Be) is much cheaper than lithium. Your team does not think that switching to beryllium in batteries is a good idea. You have a meeting coming up with him. You plan to convince him that lithium is a better choice than beryllium for creating lightweight, and energy efficient batteries. Use your knowledge of periodic trends to create a slide with your team to present to him! Use the following concepts and terms in your argument: ionization energy, Does Li or Be have a greater ionization energy? Why does this matter? atomic mass Does Li or Be have a greater atomic mass? Why does this matter? Conclusion :

Report all answers with the proper number of significant figures. In an electrolysis experiment similar to the one employed this experiment; a student observed that his unknown metal anode lost 0.238 grams while a total volume of 94.50 mL of hydrogen was being produced. The temperature of the solution was 25oC and the barometric pressure was 739 mm Hg. The difference between the water levels in the beaker and buret was negligible. The vapor pressure of water at 25oC is 23.8 mm Hg. Based on the information provided and the lab handout, what pressure of hydrogen is collected, in atmospheres? Note: Your answer is assumed to be reduced to the highest power possible. Your Answer:__________x10 units_____ Using the data collected, calculate the moles of hydrogen collected.
