Tiny Tina Psychoanalytic Tiny Tina is a character within a videogame called Borderlands 2. She has no concept of empathy for other people and almost no concept of ego or superego. She demonstrates that she is all id because she likes explosions… and in particular, blowing people up with those explosions (She feels no remorse afterwards). She is introduced by blowing up a bandit. Her go to defense mechanism would be denial. TIny Tina has her own downloadable content called “Tiny Tina’s Assault…

My earliest memory of science is from 5th grade in Mr. Kern’s class. I remember we had a unit on sea creatures, and we got to take care of and study fish and crawfish. I loved this activity because it was so hands on and we were the caretakers of the creatures, so we did all the work. It was really our own experiment, not just something out of a book. We all loved coming into class in the morning and running to see our new pets, and one day I noticed my crawfish had lost its shell. We learned…

colligative properties studied in this current chapter of chemistry are: vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure. The van’t Hoff factor for a solute is equivalent to the number of particles, in moles, will break apart in the solvent. When an…

Acid ((g/L)/(given density)) * 100 ((35.85 g/L)/(1005 g/L)) * 100 = 3.57% UNKNOWN ACID 1) Moles of NaOH ((Vf - Vi)/1000) * M Run #1: ((31.11 – 0.51)/1000) * 0.2116m = .006475 Run #2: ((31.35 – 0.38)/1000) * 0.2116m = .006553 2) Calc Moles of Acid because 1:1 ratio moles acid equals moles NaOH moles acid = Run 1: .006475 and Run #2: .006553 3) Molar Mass (grams used/moles acid) Run #1: (1.3160g/.006475) = 203.24 g/mol Run #2: (1.3276g/.006553) = 202.59 g/mol…

problem of the experiment was to determine the volume of one mole of H_(2(g)) at STP. In a way, the problem is essential in understanding how one mole of an ideal gas at STP is always equivalent to 22.4 L. By determining if the volume of a mole of H_(2(g)) is 22.4 L, it supports Avogadro’s law that one mole of an ideal gas occupies 22.4 L at STP. At the same time, it indicates that a direct relationship exists between volume and the number of moles of gas as temperature and pressure stays…

and 4. Periodic tables vary in atomic mass slightly and this slight difference of atomic mass of elements could in turn change the value of calculated molar masses in experiments 2 and 4. Lastly, the molar mass of air was given to be 28.8 grams per mole and this could in fact be different from the true air mixture of the lab in which the experiment was conducted. A variety of conversion factors were utilized to calculate data and similar to periodic tables, most conversion factors vary slightly…

Moles 1.How is molar mass calculated and why is it useful? Molar mass is calculated by going to the periodic table finding each mass of each element in the compound then adding them all up based on how many of those elements are in the compound. 2.Define a mole in chemistry and give 3 examples equivalent units that are used in chemical calculations. Mole is considered the unit for amount in chemistry other units that are equivalent are atoms, formula units, and molecules. Gas Laws 3.How is the…

Eurycea rathbuni otherwise known as Texas Blind Salamanders are incredible creatures that do not get their fair share of attention compared to animals such as cheetahs and lions. Specifically, they are only known to reside within the dark water filled caves of Edward’s Aquifer in Hays County, Texas.5 Thus, this species was discovered by the San Marcos National Fishery, which is now known as Texas State University.5,6 In 1967, Eurycea Rathbuni was listed as an endangered species, and within ten…

Sink or swim 50 years back most everyone heard the story of how humans had evolved over time. It was claimed that our ancestors, apes, had been separated between jungle and desert. Comparing physical traits of both apes and humans, there is a dramatic difference. Apes on four legs, covered in layers of fur… Then there are the humans, standing tall upon two legs, having no fur. The original theory is that when our ancestors parted in two opposite environments they had simply adapted different…

1997 documentary film Fast, Cheap and Out of Control, Errol Morris directs the fascination of a man’s action that profoundly emanates his relationship with the world around him. The four men: Dave Hoover, a Wild Animal Tamer; Ray Mendez, the Hairless Mole-Rat Specialist; George Mendonca, a Topiary Gardener; and Rodney Brooks, a Robotic Scientist, each obsessed to create unconventional worlds of their aspirations. The film has a disrupted narrative format, interweaving interviews with the men…
