Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

Factors affecting the rate of reaction between a metal and an acid The rate of a reaction can be measured by the rate at which a reactant is used up‚ or the rate at which a product is formed. The temperature‚ concentration‚ pressure of reacting gases‚ surface area of reacting solids‚ and the use of catalysts‚ are all factors which affect the rate of a reaction. Individual properties of substances also affect reaction rates. The scope of these properties is broad and there are few generalizations

Experiment 15 Title: Equilibrium studies Objective: 1. To study the effect of concentration and temperature changes on equilibrium. 2. To predict the direction of the net reaction in an equilibrium system by Le Chatelier’s principle. Results: Part 1 (a): Effect of temperature changes on equilibrium Cu(NO3)2 (aq) Cu(NO3)2 (s) The color of the solution = dark blue with precipitate When placed in water bath 60oC When placed in ice bath The level of the solid

Reaction on Reaction Paper The first thing that came to my mind when I have heard about Reaction paper is “What exactly is it?” and before I get an understanding of that‚ I resisted that change. But later‚ when I have studied about it and understood its purpose‚ I have started thinking “Why people avoid change at the first look without an analysis?” The general human tendency is to live in a comfortable zone in which he has lived for quite some time. He draws a circle‚ thinks that circle is his

Usually the power of the present societies is tripartite. The power is divided into an executive‚ a legislative and a judicative part. As though is it also in the science fiction film Equilibrium written and directed by Kurt Wimmer. After World War III only one civilised stronghold is left‚ the city-state Libria. The city-state contains the same structure of state as we know it today from totalitarian states. However the power of state is tripartite and Preston is part of the executive apparatus

CHEMICAL EQUILIBRIUM I. Introduction In a chemical reaction‚ when reactants are mixed together in a reaction vessel‚ the whole of the reactants do not get converted into products. After some time‚ there will come a point when a fixed amount of reactants will exist in harmony with a fixed amount of products; neither amount will change anymore. This state is called chemical equilibrium (Birk‚ 1994; Jones‚ 1987; LeMay‚ 2002). There are three characteristics of a system in chemical equilibrium: a. the

Proving declaration of trust and effecting disposition of beneficiary’s interest Proving declaration of trust: In order to prove declaration of trust all types of evidence are admissible. Exceptions: a) Trust of land where the declaration has to be manifested and proved by some writing (Section 7 of Statute of Fraud Act 1677; Section 53(1)(b) of Law of Property Act 1925). The reason for this rule is to prevent fraud (Youdan). The written evidence can antedates or postdate the declaration

Title: Factors affecting reaction ratesProcedure A: Effect of ConcentrationAim: To investigate how the concentration of a reactant affects the rate of reaction. Hypothesis: The more concentrated the reactant‚ the faster the rate of reaction. Materials: 2M hydrochloric acid solution‚ magnesium wire‚ distilled water‚ 4 test-tubes‚ measuringcylinder. Procedure:1)10mL 2M hydrochloric acid solution is poured into a test-tube using a measuring cylinder. 2)A 3cm length of magnesium wire is added to
