This work shows the experimental data of excess properties at several temperatures and the vapor–liquid equilibria (VLE) obtained for four binary systems of alkyl methanoates (methyl to butyl) with decane, all measured at constant... more
The moisture accumulation within clothing is a serious problem for sportswear and clothing in cold climate. There are several experimental methods available to measure moisture build up in insulate materials. However, information on... more
The adsorption of lead onto date palm fibers (palm fibers) and leaf base of palm (petiole) has been examined in aqueous solution by considering the influence of various parameters such as contact time, solution pH, adsorbent dosage,... more
Chemistry HL IB IA: higher level internal assessment
The effect of high-pressure (HP) treatment (100–400 MPa for 15 or 30 min at 20 °C) on the rheological characteristics and colour of fresh and canned mango pulps was evaluated. Differences were observed in the rheological behaviour of... more
— This experiment aimed determining the enthalpy of neutralization for the strong acid-strong base and weak acid-strong base reactions. Coffee-cup calorimetry was applied to equimolar concentrations of both hydrochloric acid and acetic... more

The various state functions that are measurable thermodynamic parameters have been defined and fully explained. The exact differentials of each of the state functions have been derived and their applications clearly examined. The Maxwell... more
The aim of the methods described is to calculate the properties of turbulent reactive flow fields. At each point in the flow field, a complete statistical description of the state of the fluid is provided by the velocity-composition joint... more
The kinetics and mechanism of methylene blue adsorption onto raw pine cone biomass (Pinus radiata) was investigated under various physicochemical parameters. The extent of the methylene blue dye adsorption increased with increases in... more
The sublimation enthalpy and entropy of urea and its derivatives monomethylurea (mmu), monoethylurea (meu), monopropylurea (mpu), dimethyl-1,1-urea (1,1-dmu), dimethyl-1,3-urea (1,3-dmu), and diethyl-1,3-urea (1,3-deu) were determined... more
Adsorption of methylene blue from aqueous solutionsonto unexpanded and expanded perlite samples activatedby H2SO4 and NaCl solutions has beeninvestigated, to assess the possibility of usingperlite for removing cationic dyes from... more
Steam Power Plant Calculation: A full run through of a steam power plant energy calculation with steam table data. Major equipment with piping interconnection figure included. Steam at 150 bar, 550 deg C is expanded in an h.p. turbine... more
Elpresente práctico tiene como objetivo principal determinar el calor de combustión a dilución infinita de una sal de magnesio en ácido clorhídrico. Para ello se verá el cambio de temperatura en el tiempo; primero se verá como es la... more
This work considers the seven-coefficient polynomials proposed by the National Aeronautics and Space Administration (NASA) to facilitate obtaining a normalized value for three thermodynamic standard-state specific properties of ideal... more
