Determination of Sulfate by Gravimetry Jose Luis E. De Guzman University of Santo Tomas‚ Sampaloc‚ Manila The determination of the percentage of sulfate in a sample is done as an instrument of learning a quantitative method of analysis‚ i.e.‚ of the gravimetric analysis. This type of analysis‚ which makes use of the weight of the samples was used for the experiment and required the precipitation of our analyte‚ SO4-2‚ and its filtration as a BaSO4 precipitate so as for weighing it. The weight

On September 8‚ 2016‚ I agreed to drink 64 ounces of water to maintain a healthy hydration level. When making a list of obstacles I failed to account for the stress and work at school. I think writing obstacles and ways to overcome them was beneficial. By having a set plan as to how to overcome obstacles I felt I had no reason to procrastinate or not do what I planned. Calling my own self out is just the wakeup call I need to stay hydrated and complete my goals. Completing and creating goals on the

Determining the enthalpy of neutralization by calorimetry Anam Iqbal Partner’s name: Danielle Hodgson TA’s name: Karinna Section # 003 Due date: November 24‚ 2009 Introduction The purpose of the experiment is to determine the enthalpy of neutralization reactions by calorimetry. Calorimetry‚ is the science of measuring the amount of heat. All calorimetric techniques are therefore based on the measurement of heat that may be generated (exothermic process) or consumed (endothermic process). The

the surrounding. Hence‚ it has a positive value for enthalpy change of reaction. In contrary‚ exothermic reaction is a chemical reaction that releases heat energy to the surroundings‚ resulting in a negative value for enthalpy change of reaction. Enthalpy change of a reaction is the heat energy change in a chemical reaction‚ for the number of moles of reactants shown in the chemical equation. Standard enthalpy of reaction‚ ΔrH⊖ is the enthalpy change that occurs in a system when one mole of matter

twice‚ once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex: volume). After all the calculations were complete it was shown to have a very small percent error.

INTRODUCTION Stock market is a market where the trading of company stock‚ both listed securities and unlisted takes place. It is different from stock exchange because it includes all the national stock exchanges of the country. Stock Exchanges are an organized marketplace‚ either corporation or mutual organization‚ where members of the organization gather to trade company stocks or other securities. The members may act either as agents for their customers‚ or as principals for their own accounts
