Enthalpy

various industrial equipment and in many engineering applications like design calculations, mass transfer, heat flow etc. The experimental vapor-liquid equilibrium data of mixtures are extremely important in designing separation equipment. Excess molar enthalpy data are required for the design of heaters, coolers, condensers etc. and also for the removal or supply of heat to chemical reactions. Densities of vapour and liquid phases are important to give a proper size in the process design of…

Adipic acid is mainly use as monomer in manufacture Nylon 6/6 fiber, plasticizer, grease, polyurethane etc. There are several countries in the world that manufacturing the adipic acid. But there also countries that just is a supplier for this adipic acid to any factory that need adipic acid in their countries. The main countries that produce adipic acid are United State of America and also China. Almost ninety percent of adipic acid manufactured in United State of America is used to produce…

Proximate analysis The analysis result of proximate composition of dried laver (P. species) has presented in Table 1. In our study, the crude protein of commercial dried laver was found to be (42.99 ± 0.051g/100g DW) and the moisture content was (9.40 ± 0.056 g/100g DW). The ash content was found (10.30 ± 0.033 g/100g DW). Laver, in this study, contained a very small amount of crude lipids (0.49 ± 0.04 g/100g DW). The total dietary fibre of dried laver was (31.63 ±0.032 g/100g DW). The total and…

Manganese dioxide (MnO2) 2. If the temperature of a reaction is decreased, what effect will this have on the rate of reaction? A. It will have no effect. B. The reaction will stop. C. The rate of reaction will increase. D. The rate of reaction will decrease. 3. Given the equilibrium reaction in a closed…

Researches related to SW/MWCNTs that shown great adsorption behavior toward heavy metallic ions possess negative Gibb’s free energy change, positive enthalpy change and positive entropy change which is the same result as studies for activated carbons[19][20][24]. The negative value of ∆G reflects feasibility and spontaneity of adsorption processes. The more negativity of ∆G marks greater driving force…

The allegory of the cave by Plato and systematic skepticism by Descartes, are arguably two of the most influential concepts within rationalism. The formulation of Plato’s work served to fight back the growing influence of fallacious sophism at the time that paid attention to rhetoric and semantics over truth. Similarly, Descartes’ approach of radical skepticism confronted the monopoly of traditional scholastic philosophy that prevailed for centuries before him. Although both concepts are…

with the Laws of Thermodynamics that both are the foundation for it, and what will eventually bring it to its end. First, it is important to give a brief introduction of the concept of energy to then fathom the topics of thermodynamics, entropy, and enthalpy, and their relation to biology. Energy is a seemingly intuitive…

High pressure turbines can and due exhaust to Medium and Low pressure turbine to regain useful energy and enthalpy still present in the high pressure exhaust steam. From there the steam in then used to power Laundry, galley, and space heating requirements, and finally gland sealing steam for packing and labyrinth seals. Steams is also used for air ejectors to…

Langmuir isotherm The Langmuir adsorption model is established on the following hypotheses: (1) uniformly energetic adsorption sites, (2) monolayer coverage, and (3) no lateral interaction between adsorbed molecules [26]. A mathematical expression of the Langmuir isotherm is given by the following equation: Where qe (mg/g) is the amount of dye adsorbed on the solid adsorbent at equilibrium, qm (mg/g) is the maximum adsorption capacity, KL (L/mg) is the Langmuir equilibrium…

Name: Ifeolutembi Fashina Student Number: 13335535 Lab Partner’s Name: Ifeoma Agu Demonstrator: Maria Inorganic Chemistry Experiment 3: The Identification of Unknown Samples Objectives The experiments were carried out in order to identify 15 samples, through their physical and chemical properties. Theory A precipitation reaction is one which produces an insoluble salt as product. An example would be; Ca(NO3)2 + H2SO4 = CaSO4 + 2HNO3 The calcium salt is insoluble. Precipitation reactions…
