experiment‚ equilibrium will be examines in the reaction beteween the iron (III) ion and the thiocyanate ion: Fe3+ (aq) + SCN- (aq) ------ FeSCN2+ (aq) The FeSCN2+ complex ion has a blood red color while the iron and the thiocyanate ion are colorless. Therefore‚ the shift in the reaction can followed by noting a change in the intensity of the clood red color‚ which indicates a change in the concentration of the complex ion FeSCN2+. If the reaction shifts to the right‚ the blood red color will get

The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to

Stoichiometry of a Precipitation Reaction March 20‚2013 Amber McCollum Introduction Stoichiometry is a branch of chemistry that deals with the quantitative relationships that exist among the reactants and products in chemical reactions To predict the amount of product produced in a precipitation reaction using stoichiometry‚ accurately measure the reactants and products of the reaction‚ determine the actual yield vs. the theoretical yield and to calculate the percent yield. The equation

Iodine-Clock Reaction: S2O82−(aq) + 2 I−(aq) → I2(aq) + 2 SO42−(aq) To measure the rate of this reaction we must measure the rate of concentration change of one of the reactants or products. Here‚ it is convenient to carry out a clock reaction involving the product I2. To do this‚ you will include (to the reacting S2O82− and I−) i) a small (but accurately known) amount of sodium thiosulfate‚ Na2S2O3‚ and ii) some starch indicator. The added Na2S2O3 does not interfere with the rate of above reaction‚ but

The chemical equation for Thiopental Sodium is C11H17N2NaO2S. First synthesized in 1935‚ the proper name for the drug is Thiopental Sodium it also goes by Sodium Pentothal but that is actually a trademark of the drug ’s manufacturer‚ Abbott Laboratories. A yellow water-soluble crystal‚ it is classified as an ultra-short acting barbiturate‚ a type of drug that depresses the central nervous system‚ slowing the heart rate and lowering blood pressure. Widely used in medicine as an anesthetic during surgery

Today‚ is my second day in concentration camp #59‚ which goes by the name Sobibor; an extermination camp. (Which is just one type of many different purposed camps‚ including prisons‚ labor‚ and transit camps.) I arrived here yesterday at roughly a quarter to noon‚ with my sickly mother Aliza and two older brothers Adam (17) and David (21). My father was brutally murdered yesterday by one of the many Nazi soldiers who invaded our home. “Eliana‚ sis‚ wake up. Protocol will begin in five minutes
