bridge decks‚ which is a very dangerous effect. In the presentation conclusion it stated that states who use road salts the most are looking into other forms of deicing. Two alternatives being considered are calcium magnesium acetate and potassium acetate. Both have low corrosive capabilities‚ but the one draw back is that they are quite a bit more expensive than sodium chloride. To this day the presentation stated‚ sodium chloride‚ even with all the known adverse effects‚ is still used

core recovery‚ water-based saline drilling fluids were utilized. A total of 5.6x105 L of fluids was lost in the subsurface. The fluid was comprised of surface seawater from the sound‚ as the wetting agent mixed with densifying compounds (mainly potassium chloride and small amounts of fourteen other compounds including biodegradable organics). When exploring pristine locations a main goal needs to be minimizing the amount of biological and chemical contamination. Introducing a contaminant such as

Flame Tests By: Jordan Anthony‚ Zack Balog‚ and Evan Degraw Regents Chemistry class‚ Union Springs High School‚ 4th period January 19/2015 The purpose of this lab was to see what colors are characteristic of particular metallic ions in a flame test and use their characteristic color to identify other elements. Another purpose is to understand how fireworks work. This experiment will help one understand how a flame test is performed and that every metal has a unique bright

The Nervous System: Membrane Potential 1. Record the intracellular and extracellular concentrations of the following ions (mM/L): Intracellular Extracellular Sodium (Na+) Potassium (K+) Chloride (Cl–) 2. Excitable cells‚ like neurons‚ are more permeable to ___________ than to ___________. 3. How would the following alterations affect the membrane permeability to K+? Use arrows to indicate the change in permeability. a. An increase in the number of passive K+ channels

Animation: Cells & Chemistry Glycolysis After viewing the animation‚ answer these questions. 1. Cells derive energy from the oxydation of nutrients‚ such as glucose . 2. The oxidation of glucose to pyruvate occurs through a series of steps called glycolsis . 3. How many carbons are in a molecule of glucose? 6 4. The energy related during these oxydation reactions is used to form adenosine triphosphate (

charcoal is too large to pass any of the membranes. 3. Pressure changed the speed of filtration but pressure does not affect the size of the solutes nor the pore size of the membrane. Activity 5 1. The SP pump ejects 3 sodium ions per every 2 potassium ions coming in. 9:6 represents the ration of the SP pump 2. Predicted that no sodium would be transported because the coupled

Ariana Focaraccio Eugene’s Story A man named Eugene was found passed out behind a bar and brought into the emergency room. He is an alcoholic ‚ has pancreaitis‚ and an enlarged liver. When he was brought in his blood levels of sodium‚ potassium‚ magnesium‚ and phosphorus were too low. His blood pH was acidotic. Eugene was found unconscious‚ but luckily‚ he suffered no head trauma. There was a lot of damage done to his liver and pancreas‚ and his doctor decided to try and get him to a rehab center

flower induction trial‚ 2% KNO3 (Potassium nitrate) was used. It is a flower inducer which contains potash and nitrogen for rapid growth of the flower. It was sprayed on the shoots of the Carabao mango tree with mature leaves. On the other hand‚ a control wherein pure water was sprayed was provided. This trial‚ if turned out well‚ should show significance of flowering even in off-season. Observation was done 14 days after spraying. Materials and Procedure: *potassium nitrate/ KNO3‚ sprayer‚ pail‚

INTRODUCTION A chemical fertilizer is a substance applied to different soils or directly onto plants to provide nutrients optimal for their growth and development. The essential nutrients contained in these fertilizers are nitrogen‚ phosphorous‚ and potassium (NPK)‚ as well as other nutritional substances in smaller amounts all presented in a form that can easily be absorbed and metabolized by plants. Chemical fertilizers have become a staple in many yards and gardens‚ and can be a key component of a
