Title: Surface Area vs. Rate of Reaction Research question: How can different temperatures affect the rate of reaction‚ when the reactant is in powder form? Hypothesis: If the temperature of the water is increased‚ the rate of reaction will also increase as the heat given off to the particles will increase leading to more movement and frequent collisions. Background information: Chemical reactions occur when two or more molecules interact with each other‚ but that can only occur when they

on top of the shorter cup to prevent any heat loss to the air. Then the shorter cup was secured on a base with tape and a hole was drilled with a stir stick on the top of the taller cup to allow the stir stick and a thermometer reach the chemical reaction. With the calorimeter set up and ready‚ the experiment was ready to be conducted. The calorimeter was placed on a metric scale and tared. Then 2.5g of a substrate was measured out using a small scoop and placed in the calorimeter. A scale was used

Flatland Reaction Paper Prior to reading this article‚ I never really thought of math to be this universal thing that could be applied over such a large horizon. I was knowledgable that‚ of course‚ everyone and everything could be eventually linked in some way or fashion to mathematics‚ but I was oblivious to how large of a spectrum it all really sits. Overlooking all of the sexist and biased opinions stated by Edwin A.Abott in this piece‚ he really opened my eyes to a different perspective of

Ridao Florencio Louis Pascual Relao De La Salle University- Dasmariñas Dasmariñas Cavite Philippines ABSTRACT The Copper Reactions experiment was demonstrate by adding the reagents like 16M HNO3‚ Distilled water‚ 6M NaOH‚ 6M H2SO4‚ Acetone‚ Zinc metal and Methanol into the beaker with the copper wire. The experiment was also demonstrated to observe how copper reacts while different reagent were being added. It was also demonstrated to practice the common laboratory

STRESS COPING MECHANISMS AMONG YOUTH (PGDM STUDENTS) 1. INTRODUCTION A word which we consistently heard and feared from the day we thought of doing management studies is “STRESS”. Management studies have been perceived as a hectic and stressful course from the inception of the same. Every individual has his own methods for coping up with the stress; like playing games‚ working out in gym‚ listening to music‚ doing yoga‚ chatting with friends etc.

and subconscious. Freud proposes that there are nine ego defense mechanisms that act the ego uses in its job as the mediator between the id and the superego. In psychoanalysis‚ an ego defense mechanism is an unconscious personality reaction that the ego uses to protect our conscious mind from threatening feelings or perceptions. The ego defense mechanisms are as follows: denial‚ displacement‚ projection‚ rationalization‚ reaction formation‚ regression‚ repression‚ sublimation‚ and suppression.

precipitation reaction is‚ describe ways which one can predict whether a precipitation reaction would form or not‚ describe the uses of precipitation reactions in everyday activities and industries BACKGROUND INFORMATION: Precipitation is the formation of a solid in a solution during a chemical reaction‚ such as evaporation. A substance that causes precipitation when it is added to a solution is called a precipitant. This can occur when an insoluble substance is formed in the solution due to a reaction or
