Abstract. An innovative and novel technology method of processing called Turbo-Mixing Reactive Precipitation (TMRP) design proposed as an alternative to this current processing or conventional productions of finer precipitation calcium carbonate (nano-PCC) in turbo-mixing conditions. In this paper‚ the effect of the stirring rate onto morphology‚ particle sizes and reaction time of the precipitated CaCO3 particles was discussed. CaCO3 nano particles with an average particle size of approximately

Copper-Iron Stoichiometry Lab Report 10/3/12 Abstract: The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate‚ CuSO4‚ mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was

Stoichiometry and Limiting Reagents Theodore A. Bieniosek I. Purpose and Theory The purpose of the experiment is to study and apply the processes of stoichiometric calculation on a controlled chemical reaction. We will be adding variable amounts of reactants in a chemical reaction in order to demonstrate the effect of limiting reagents. Based on the volumes of the reactants‚ and their respective molarities‚ we can calculate the theoretical yield of the reaction and compare it to the

Students’ Conceptual Understanding of Stoichiometry. Introduction Stoichiometry is one of the major concepts in chemistry. Conceptual understanding in stoichiometry is crucial for any student taking chemistry as a subject as many areas in chemistry are highly related to this conceptual understanding. Many previous researches found out that students poses a very low conceptual understanding and they also poses many alternative conception related to stoichiometry. Dahsah. C; Coll. R.

all the excitement and adventures couldn’t mean as much as her mother. The film‚ Hook‚ is relatively a recent version of J.M Barrie’s Peter Pan‚ which was first introduced in 1902 novel‚ The Little white bird. There have been many other versions created‚ including Peter and Wendy‚ which was published in1911 and Walt Disney’s 1953 animation‚ Peter Pan. There are few unchanging elements‚ which are responsible for the story’s worldwide reputation and its survival. However‚ most people

I suddenly‚ and quite strangely‚ have found myself conflicted about Peter Pan. I thought I knew the story‚ believed I was familiar with it. My Mother has used the term "Peter Pan Syndrome" to describe nearly every young member of our family at one time or another. It means you never want to grow up‚ just like the boy in Walt Disney’s animation. Peter wants to play in Never Land forever and avoid responsibility while careening through the air amid pirates and redskins and a strange yet hopeful band

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

tricks the viewer and the detective to believe that Peter is the killer. There is never any direct evidence to indicate that Peter murdered anyone. Peter’s Schizophrenia is used as an explanation for his strange behavior and for his reason of presumed murder. The idea that the classification affects other people’s perception and expectation of those classified in a certain category is well illustrated through the librarian who when asked if Peter did anything to her‚ answers “He didn’t do anything
