Potassium

A. After having viewed the 'Anatomy of a firework' interactive answer the following: What are the different parts that make up a firework? Fireworks have a few different parts such as Potassium Nitrate, Charcoal, and Sulfur and they use different chemical compounds to create three kinds of results: A tremendous "boom" A bright light Heat What is the recipe for black powder? Why do you think Potassium Nitrate, Charcoal, and Sulfur become explosive after they are ground together? Black Powder is a mixture of Potassium Nitrate, Charcoal and Sulfur. The Sulfur and Charcoal act as fuels, and the Potassium Nitrate is an oxidizer. Black powder is used in fireworks because it consists of potassium nitrate (75%), charcoal (15%), and sulfur (10%). Each…

This paper will discuss the management practices that can be implicated to help control the severity of Hyperkalemic Periodic Paralysis in affected horses. Because of the debilitating effects that this condition has, it is important to examine the ways that this disorder can be controlled. Low potassium diets, regular turnout, and a constant schedule have been shown to effectively manage the condition of Hyperkalemic Periodic Paralysis. The role of potassium in action potentials, as well as in…

K2CrO4 was added in Step 12 and this was what indicated whether or not the sample from Part B contained barium or not. The chloride ion in potassium chromate bound to the barium cation and formed a precipitate, if there were any calcium cations present, they would have stayed in the liquid solution. If the substance in Step 12 remained cloudy, it would have been a sign for a false positive. This refers to a result that may not be correct, and if it were the case, a precipitate of barium may have…

The instructor brought forth three sea urchins from the tank in the back of the room. The three sea urchins were then injected with .5M of potassium chloride (KCl) and placed mouth up into a 120 mL of seawater. After waiting for 10 to 15 minute time interval there was no reaction from the sea urchins. The lab instructor injected another .5M of potassium chloride (KCl) and placed into 120 mL of sea water mouth up. Once all three were placed into containers with the seawater solution they…

amounts of water to determine the minimum amount needed to completely dissolve the salt. The cation test told whether the unknown contained barium, calcium, potassium, sodium, strontium, lithium, copper, or magnesium. Given a chart of the colors that each burn, lit the unknown on fire with a bunsen burner and compared the flame color with the colors in the chart. In order to identify the anion, we needed to perform four anion reactions: chloride, sulfate, nitrate, and carbonate. To identify…

from chronic ketosis can be drawn on to synthesize ATP during periods of metabolic stress, such as during a seizure. Typically, when an excitatory action potential is fired in a neuron, ion channels open that allow for the flow of sodium ions to flow down its electrochemical gradient into the neuron, resulting in depolarization. For the neuron to return to its resting potential, sodium potassium pumps located in the neuronal membrane pump three positively charged sodium ions out of the neuron…

of nausea and acutely vomiting because of the pains in his stomach and throat. He was immediately rushed to the ED. His symptoms are diaphoresis, motor dysfunction, parethesias, nausea, ascending paralysis, cyanosis, and hypoventilation. He was prescribed with atropine due to the bradycardia. As he was assumed to be poisonous with tetrodotoxin which is a neurotoxin, intravenous hydration, gastric lavage and activated charcoal was conducted next. Background The extracellular fluid and…

After the experiment was conducted and the data was analyzed the cation in the solution was proven to affect the color of the flame. The cation in each of the solutions are calcium, copper, lithium, and potassium. The two salt solutions that have calcium as its cation are Calcium Chloride and Calcium Nitrate. When you compare those two solutions you can see that both of their flames turned orange. The two salt solutions with chloride as their anion were Calcium Chloride and Lithium Chloride.…

drawing represents potassium. I drew a banana because they are high in potassium. I also drew water (h2o) which is very violent when it hits potassium (k). The elephant itself represents element potassium. The red color of the elephant symbolizes it being burnt from the water. When water hits potassium it creates a massive explosion resulting in the elephant being wounded. The elephant undergoes a lot of corrosive reactions. The ionization decreases and the metal activity increases causing this…

marismortui’s two pch proteins, pch1 and pch2, are structurally very similar and in fact both contain a TrkA N-domain (Figure A and D) (Mitchell, et al. 2015). Despite these similarities, both show dissimilar expression patterns in Har. marismortui under low potassium stress conditions (20mM potassium) after acclimatization at normal potassium levels (120mM potassium). When experiencing low potassium shock, pch1 mRNA has a large expression spike 4 hours after introduction to new conditions…
