THERMAL INSULATION MATERIALS Thermal insulation materials are specifically designed to reduce the heat flow by limiting heat conduction‚ convection‚ radiation or all three while performing one or more of the following functions: The main function of insulation is to reduce the heat transfer‚ the insulation material must have the appropriate characteristic to slow down the transport of heat occurred by conduction‚ convection and radiation. Conduction loss in insulation is negligible. There are

Lab O6 – Equilibrium Lab Application Purpose: An introduction to the qualitative aspects of chemical equilibrium. Starting with a reaction at equilibrium‚ one will change the concentration of various ions present in the equilibrium‚ and record the states of the changing equilibrium through observation. Theory: Equilibrium- the point at which a solution has become perfectly saturated; when their forward and reverse reaction rates are equal Concentration- a measurement of how much solute

Determination of Equilibrium Constants Introduction Bromothymol blue is an indicator for many acid-base titrations. When adding different solutions within the indicator it is to react and change colors‚ in this experiment the different colors were blue‚ green‚ and yellow. In the following experiment‚ obtaining the absorbance levels for each one makes it possible to calculate the equilibrium constant. Materials and Methods For this specific experiment there are a few materials that are crucial

you observed in the experiment and answer these questions: A. Which way should the equilibrium shift when HCl is added? How do your results support your answer? It should shift to the left because adding any component causes the equilibrium to shift to the opposite side. B. Which way should the equilibrium shift when Na2EDTA is added? How do your results support your answer? It should shift to the right because the removal of a component causes the equilibrium to shift to the side

DISCUSSION Chemical equilibrium and its different applications were studied in this experiment. The Le Chatelier’s principle‚ which is the main principle behind chemical equilibrium‚ states that‚ “If an external stress is applied to a system at equilibrium‚ the system adjusts in such a way that the stree is partially offset as the system reaches a new equilibrium position.”[1] The “stress” can be a change in concentration‚ volume‚ pressure‚ or temperature that disturbs the equilibrium

Introduction: Chemical equilibrium is when the concentrations of the reactants and products have reached a state where reactions occurring in one direction are at the same rate of reactions occurring in the opposite direction. This process‚ called dynamic equilibrium‚ is the main subject of Le Chatelier’s Principle. Le Chatelier pointed out that if a system at equilibrium is subjected to a stress that momentarily causes the system to be not in equilibrium‚ a spontaneous change will occur to
