if medical attention is not given‚ the situation may be life threatening. What is the treatment of Heparin overdose? The medical care provider will give protamine sulfate through slow infusion. The amount of administered will depend on the excess Heparin taken. Normally‚ 100 units of Heparin is neutralized by 1mg of protamine sulfate‚ however‚ the maximum amount given is 50 mg within a period of 10 minute and the amount needed reduces

Earth Batteries Dirt makes pretty good batteries. It seems like moist dirt packed tightly works the best. Add just enough water but not too much. I guess if the dirt dries up‚ you’ll have to water the batteries along with the rest of the plants. The soda can version works but I haven’t tested extensively. You don’t really have to use a penny‚ just has to be copper. Perhaps other common materials would work better. Each cell gives you a useless 0.5 volts. But if you link them in series you can

A precipitation reaction that could be used is hydrochloric acid Ag+(aq) + HCl(aq) AgCl(s) +H+(aq) – white. 2. What precipitation reaction could be used to separate and remove iron (III) ions from the remaining mixture containing iron (III) and zinc ions? Fe3+(aq) + 3NaOH(aq) Fe(OH)3(s) + 3Na+(aq) 3.

protein‚ and three samples containing proteins‚ and using a spectrophotometer we assessed the amount of light absorbed versus the light transmitted‚ based on the principles of the Beer-Lambert Law. The three proteins used included lysozyme‚ protamine sulfate‚ and bovine serum albumin‚ and the three non-protein samples contained either RNA‚ tyrosine‚ and glycylglycylglycine. Standard curves were created to exhibit the linear relationship between the concentration of solute (protein‚ non-protein) and the

The enzyme tyrosinase was successively extracted by combining a homogenate of a potato and sodium sulfate with ammonium sulfate. Tyrosinase was successfully extracted by taking advantage of solubility properties of certain proteins. A standard curve was generated indicating dopachrome absorbance values through the use of a spectrophotometer and a computer graphing program. A spectrophotometer was used to measure either the amount of light that passed through a solution (transmittance) of the amount

will perform a quantitative analysis of a two-step reaction. Copper(II) oxide will be synthesized from a known mass of copper(II) sulfate pentahydrate. Using the relationship of the balanced equation‚ and other stoichiometry relationships‚ you will calculate a theoretical yield of CuO‚ and your actual yield. You then will calculate a percent yield. Copper(II) sulfate pentahydrate will be dissolved in water and reacted using a double replacement reaction with sodium hydroxide. The addition of hydroxide
