LAB 1: Cheesemaking with Enzymes 9E Chihiro Okada Introduction 1. Enzymes - are biological catalyst. 2. Enzymes - are proteins that catalyze chemical reactions. Emporase – an enzymes that speeds up the production of cheese. 3. First milk is pasteurized by heating it to 72℃ for 15 seconds to kill any harmful bacteria. Then‚ the milk is cooled and either a special blend of bacteria or an acidic solution - such as vinegar or lemon juice - is added. The milk is

CHEMICAL KINETICS RESULTS AND DISCUSSION The balanced equation of the reaction between sodium thiosulfate and Hydrochloric acid is: S2O32- (aq) + 2 H+ (aq) SO2 (g) + S (s) +H2O (l) Using beakers with the same diameter was very important in conducting the experiment. If different sizes were used‚ the visibility of the “x” on the paper beneath the beaker could disappear from view too early or too late than the hypothetical time depending on the depth of the solution. It was also significant

Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment
