    change in temperature‚ compared to Reaction 3’s change in temperature. Reaction 1 was the dissolution of solid sodium hydroxide in water with a ΔH°rxn of -47047 J/mol‚ Reaction 2 was the neutralization of liquid sodium hydroxide with HCl with a ΔH°rxn of -31289 J/mol and Reaction 3 was the dissolution and neutralization of solid NaOH with HCl with a ΔH°rxn of -91000 J/mol. Consequently‚ the sum of Reaction 1 and Reaction 2 was -78336 J/mol‚ similar to the ΔH°rxn for Reaction 3. Table 2 displays the percent

    Introduction Memory is defined as the faculty by which the mind stores and remembers information(Eysenck & keane‚ 2010). Atkinson and Shiffrin (1968) (Cowan‚ Rouder‚ & Stadler‚ 2000)‚ came up with a model of sensory memory which stated not everything we perceive we process. Craik and Tulving (1975) developed an opposing theory in which they proposed the levels of processing theory‚ stating its not the processing but the type of quality of the processing that is performed‚ that determines the retention

    INTERPRETATION OF RESULTS: This experiment circles around with the Newton’s second condition of equilibrium in rotational motion. It describes by net torque acting on a body which is zero. The ability of the body to rotate in a certain direction is varied according on how much torque is applied. To prove that‚ a beam that is subjected to two forces is balanced by adjusting the perpendicular distances. When applied force is weight‚ modification in masses added is also done. Once equilibrium is achieved
