Get Charged Up Lab Report Abstract Get Charged Up Magnesium ribbon was reacted with Hydrochloric acid in three different experiments to determine the charge on a metal ion. After running multiple tests in the three different procedures‚ the Crystallization method proved to be the best method for determining the charge of the metal ion by using mole to mole ratio. Introduction The objective of the Get Charged Up lab was to determine the charge on a metal ion reacting with HCl by determine

Methods I planned my experiment to test the effects of topical chemicals on bacteria living on my hands. In doing this experiment I used hand soap and hand sanitizer on the living bacteria. I followed the procedure for setting up the bacteria culture as listed in the lab manual. I swabbed the bacteria sample from my palm‚ fingers and finger tips. In addition to the two experimental variables‚ I had two separate control quadrants‚ one containing water and the other containing bleach. After completing

In our Mediaphys Lesson I learned that the primary structure of a cell membrane is made up of a double layer of phospholipids molecules. The hydrophilic heads of the phospholipid molecules face outwards towards the water base solutions inside and outside the cell. The membrane is also made up of proteins‚ carbohydrate molecules‚ and cholesterol that form gates and pores‚ cell recognition‚ and stability. Active transport is used when a cell needs a substance to cross the membrane against its concentration

Aqualisa Quartz Case Write up Problem: Aqualisa is suffering from a lack of sales momentum with their new Quartz product line due to a lack strategic promotion. The firm is has boldly attempted to innovate the electric segment of the UK’s shower market. Unfortunately plumbing products have little brand recognition amongst consumers and Aqualisa has a small share of the electric shower market further reducing their new product’s visibility. As electric showers have a reputation of being problematic

biology sbi4uo-a | Osmosis and Diffusion Lab | By: Elora Hobbin | | Group Members : Ashley Riley-Roy and Adam Reynolds | 9/11/2012 | | Introduction: Osmosis and diffusion are two procedures that are critical for cell survival. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. Osmosis is the movement of water molecules across a cell’s membrane. These two procedures help a cell to survive because they help maintain homestasis

Land Snail Practical Write Up Land snails are used as an archaeological methodology of reconstructing the past and are an environmental method that can fill in the gaps of other methods. For example‚ pollen and macroscopic plant matter study show the general change of a large area and only survive when waterlogged. Chalk lands are prime archaeological landscapes useful for study and land snail evidence can survive in them where other evidence cannot. Also‚ as oppose to representing a large scale

of this molecular movement. Diffusion is the random movement of molecules from an area of higher concentration to areas of lower concentration. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane that only allows certain molecules to diffuse though (Lab Manual 7e‚ 2010). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no net movement will occur

Experiment to determine absolute zero using Charles’s law In this experiment you will be determining the specific heat capacity of oil using an electrical method. You will need to ensure that your write up contains the following: • Clear method (bullet points are ok) and labelled diagram include what is to be repeated and averaged. • State independent/dependent and control variable(s) • State what is to be varied and how (include range and intervals)? • What is to be measured and what with
