Introduction. The following is an experiment into temperature change in an exothermic reaction taking place between Sodium hydroxide (NaOH) and Hydrochloric acid (HCl) and also how the concentration of the acid will vary these results. The characteristics of the reaction feature a neutralisation‚ an energy change (shown as a temperature change) that is usually exothermic (gives out heat). The reaction of neutralisation is exothermic because of the bonds being broken and made in the reaction. When

Last Friday in class‚ we wrote a CTA about Emily Dickinson’s poem and had an ORB discussion. For the ORB project‚ our group read Salt to the Sea by Ruta Sepetys. The book is about four characters‚ who are the refugees from the World War II‚ and how they interact with each other. To be honest‚ in class‚ I did not raise any deep‚ philosophical question about what I was doing. I simply followed what I was asked to do.

Investigating Stoichiometry with Carbonic Acid Salts Problem: Testing the actual yield versus the theoretical yield of NaCl when HCl is titrated into Na2CO3 and NaHCO3. When 0.15g of both NaHCO3 and Na2CO3 are titrated with HCl‚ then 0.165g of NaCl should form from the NaHCO3‚ and 0.104g of NaCl should form from the 0.15g of Na2CO3. Procedure: Weigh 2 samples of 0.15g of dried unknown each‚ and dissolve each into 50mL of distilled water. Add 0.5 to 1mL of bromocresol green indicator until the
