CALORIMETRY Abstract: During the experiment‚ the group were able to perform the following objectives; to compute the heat capacity of a Styrofoam-cup calorimeter‚ and also to compute the heat of neutralization of 1.0 M hydrochloric acid and 1.0 M sodium hydroxide‚ the heat of dilution of concentrated sulfuric acid‚ and the heat of solution of solid ammonium chloride The sixth experiment was named "Calorimetry" wherein it is the measurement of how much heat is gained or released by a system

INGUITO INTRODUCTION Calorimetry‚ derived from the Latin calor meaning heat‚ and the Greek metry meaning to measure‚ is the science of measuring the amount of heat‚ q.1 The amount of heat is absorbed (endothermic where qrxn >0) or released (exothermic where qrxn <0) by the system with

Chem 17 ▪ General Chemistry Laboratory II Experiment 1 Calorimetry INTRODUCTION Chemical reactions are usually accompanied by the evolution (exothermic reaction) or absorption (endothermic reaction) of heat energy. When measured at constant pressure‚ the heat evolved (qp < 0) or absorbed (qp > 0) is equal to the enthalpy change‚ symbolized by ΔH. ΔH is positive for an endothermic process and negative for an exothermic one. If H f is the enthalpy of the final state and Hi of the initial state

From field to cup… How coffee is made Do you ever wonder how coffee is made? It’s not a simple process. There are three stages to make coffee: harvesting‚ processing and roasting. The first stage of making coffee is harvesting. Coffee trees take 3-5 years to produce their fruit and they require special attention to soil‚ light and climate to produce a quality harvest. The cherries are either picked by hand or machine harvested. Once harvested‚ the fruit must be removed from the cherry

Experiment 1: Calorimetry INTRODUCTION In the calibration of the calorimeter‚ the net ionic equation used is H+(aq) + OH-(aq) H2O(l). The reaction released heat and is said to be exothermic. HCl is the limiting reactant of the reaction and o.oo5 moles of it was used. The heat generated by the reaction is 55.8 kJ. The sign of T of the reaction used for calibration is opposite to that of H. In the determination of heats of reaction‚ the reaction of 15 mL 1 M CuSO4 + 0.05 g Zn produced a

color of cups affects people’s rating of coffee. I remember when I did this experiment on Jenny‚ one of the teachers in THSI‚ she was surprised by the different flavor in different cups. I accepted some of my hypothesizes‚ and some is still unsure. The glass cup can provide the strongest feeling to the testee. And‚ the dark blue cup can enhance the sensation of either sweetness and bitterness. Besides‚ due to the close percentage between blue and white cup‚ it can not prove that white cup is more
