A REACTION PAPER demonstrates comprehension of the assigned readings and contain a critical and thoughtful reaction to the reading. Reaction should make up the majority of the Reaction Paper. Make sure that your paper is in the form of an essay with an introduction‚ body and conclusion. a) Focus on an aspect of the reading that you will argue pertains to some issue or idea’ “Does the reading support‚ undermine or come into tension with previous issues or concepts?” Explain why it is significant

Stephany Matos Chem Lab: Chemical Equilibrium Lab 52 Synopsis Iron (III) ions react with thiocyanate ions (SCN-) to form iron (III) thiocyanate‚ FeSCN2+. It is represented in the equation below: Fe3+ (aq) + SCN- (aq) FeSCN2+ (aq) Therefor the equilibrium constant for this reaction is: KC = [FeSCN2+]/([Fe3+]•[SCN-] For this experiment we were able to determine the equilibrium constant KC for this reaction. First we prepared five different mixtures with known initial concentrations of

Rates of Reaction Coursework Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate. Both of the chemicals are clear solutions and they react together to form a yellow precipitate of sulphur‚ the equation for this reaction is: Na2 S2 O3 + HCL‚ H2 O + NaCL + SO2 + S Sodium Thiosulphate + Hydrochloric

pyrite. Oxidation of sulphides in contact with air and water produces sulphuric acid which reduces the pH of water. The result of these reactions is increase in the solubility of heavy metals and consequently pollution of water resources. The Sarcheshmeh copper mine is one of the largest porphyry copper mines in the world which is located in south-eastern Iran. Chemical analysis of over than 600 water samples taken from streams and springs in the mining region and surrounding area of pit showed extensive

lobe of the brain can cause an individual to develop different impulses and as well impulsive behavior (Schwartz‚ 2012). There are even disorders and illnesses such as Depression‚ Schizophrenia‚ and Bipolar Disorder believed to be the result of chemical imbalances in the brain. However‚ biological factors can also determine decisions and actions. Pharmaceutical medications have shown that people make different decisions when on the medications versus when not on them.

The reaction rate for the heterogeneous reaction A(g) + B(l)→ products is second order according to the expression -rA=kCACB and it is relatively slow compared to mass transfer so it takes place in the bulk of the liquid. Combine the following rate expressions for diffusion through the gas and liquid films‚ -rA=kAga(pA-pAi) and -rA=kAlaCAi-CA‚ with Henry’s law pAi=HACAi

precipitation reaction is‚ describe ways which one can predict whether a precipitation reaction would form or not‚ describe the uses of precipitation reactions in everyday activities and industries BACKGROUND INFORMATION: Precipitation is the formation of a solid in a solution during a chemical reaction‚ such as evaporation. A substance that causes precipitation when it is added to a solution is called a precipitant. This can occur when an insoluble substance is formed in the solution due to a reaction or
