DETERMINATION OF ENTHALPY CHANGE OF NEUTRALIZATION IA Criteria Assessed: DCP CE MS Introduction When an alkali neutralizes an acid‚ a salt and water are formed. Aqueous hydrogen ions (H+(aq)) from the acid react with the hydroxide ions (OH- (aq)) from alkali‚ forming water. The identity of salt will depend on the nature of the acid and alkali used. H+(aq) + OH- (aq) → H2O(L) The combination of H+ and OH- ions in this way releases energy. In this practical‚ the enthalpy changes accompanying

Calculation on the molar enthalpy change of a neutralization reaction Principle H2SO4(aq)+2NaOH(aq)=Na2SO4(aq)+2H2O(l) The reaction is a exothermic reaction‚ when the heat released by it is absorbed by water‚ the temperature of the water increases. The heat produced by the reaction can be calculated if it is assumed that all the heat is absorbed by the water. Heat change of reaction=-heat change of water =-mH2O×cH2O×△TH2O As the water has gained the heat produced by the reaction‚ the heat change

According to the essay “Too Much Pressure” by Colleen Wenke‚ the reason that students cheat on their tests is because they are under too much pressure to get good grades‚ which is accurately portrayed since cheating is usually seen as one of the only ways to pass tests and that’s what students are being stressed to do. Based on her essay‚ teachers should be teaching students right from wrong as opposed to pressuring to the extent of making them cheat. This is important to see because it is a way

Measuring the enthalpy change of vaporisation of water You should attempt this part of the activity even if you have not seen the demonstration of the practical. 1. Calculate a value for ∆Hvap for water in KJ mol-1 using the data from the demonstration. Also‚ calculate ∆Hvap from the following data gathered by a student; 8100 J were needed to distil 2.95g of water. a) Explain why the boiling tube was surrounded with expanded polystyrene (or other similar insulation)‚ but the condenser was left

Determination of the Enthalpy for Decomposition of Hydrogen Peroxide Objective: To construct a coffee cup calorimeter‚ measure its calorimeter constant‚ and determine the enthalpy of decomposition and formation of hydrogen peroxide. Background: This experiment is a classic thermodynamics lab. In it‚ we attempt to measure the enthalpy (H) of a chemical reaction. The main obstacle is that this is a quantity that cannot be measured directly. It instead is observed as heat from one substance is transferred

24-Hour Blood Pressure Monitoring In some patients‚ an elevated blood pressure reading taken during an office visit may not truly indicate hypertension—it could just be an occasional occurrence. These individuals are given a portable device to record their blood pressure over a 24-hour period. This helps us more accurately determine whether or not a patient usually has high blood pressure and requires treatment. Advanced Lipid Profile An advanced lipid profile test gives more information than

It’s a Tuesday. I’m finishing my workout at my neighborhood gym. I walk into the locker room‚ throw my clothes off‚ and head to the showers. The water is warm. I’m feeling like a real go-getter. The endorphins‚ the steam – it’s relaxing. Veeery relaxing. I take a handful of the shower gel that the gym supplies in buckets and start lathering up. I’m making sure things are clean down there. Really‚ really clean. (Not really‚ readers – I’m jerking off. Duh.) So I’m a showerbater; I admit it. I like

A pressure gauge is an instrument that measures the pressure in a vessel‚ a line‚ or whatever the pressure gauge is connected to. A Bourdon gauge consists of a C-shaped pipe with one end closed and the other end attached to a chamber whose pressure is being measured. When there is a pressure difference between the inside of the pipe and the outside‚ there will be a net force acting on the C-shaped pipe which will either try to curl the pipe into a tighter C shape (if the pressure in the pipe is
