The purpose of this lab was to determine the concentration of NaCl or sodium chloride that is isotonic to elodea cells. First off‚ what is osmosis? Osmosis is this huge net of molecules moving through semi-permeable membrane to high concentration to direction where everything becomes balanced. This brings us to what osmolality is. Osmolality is related to osmosis and we know that osmosis has something to do with water so that being said‚ osmolality is number of osmoles of solute per liter in solution

3.2 “Lab-on-a-Chip” A Lab-on-a-Chip (LOC) device‚ also known as a micro-total-analytical system (microTAS) or microfluidics device‚ is a device that can integrate miniaturized laboratory functions (such as separation and analysis of components of a mixture) on a single microprocessor chip using extremely small fluid volumes on the order of nanoliters to picoliters. From a technology categorization perspective‚ LOCs can be viewed as a subset of microelectromechanical systems (MEMS) and combine

Acid/Base Titrations Pre- Lab Questions 1. Using your textbook or a handbook‚ look up the formula and structure of potassium hydrogen phthalate (KHP) used to standardize the solution of NaOH in this experiment. Calculate the Molar Mass of KHP. Molar Mass= 204.22 g/mol Formula: KC8H5O4 2. Using your textbook or chemical dictionary‚ write the definition of indicator. Indicator- a substance added at the beginning of the titration that changes color at (or very near) the equivalence

“Iron Mike” Webster labored in football like a possessed man‚ he had great work ethic on the field. He always showed great power during games for his fans who all saw him as a local superhero. He played as a center on the Steelers for fifteen seasons from the 1970’s to the 1980’s. He helped his team through four super bowls and his exploits made him a candidate for a football hall of famer. That’s exactly what he became after showing multiple examples of courage like his own personal hero John Wayne

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With
