Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will

Reaction to Citizen Kane movie The movie Citizen Kane was an interesting and thought provoking movie. Set in the early 1940’s this movie was about a man named Charles Foster Kane‚ a multimillionaire newspaper writer for a company called RKO.

Where else is there a better place to start then childhood? Charles Kane was raised in

Introduction The reaction rate of a chemical reaction is determined as the change in the concentration of a reactant or product over the change in time. [1] The rate of a reaction is determined by experiment. Many factors influence the rate of a reaction: the nature of the reaction‚ concentration‚ pressure‚ temperature‚ and surface area‚ presence of catalyst and intensity of light. [2] For a chemical reaction‚ the rate law or rate equation is a mathematical expressed equation that links the reaction rate with

Section: 9 - Malaya Topic: Types of Chemical Reaction A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons‚ leading to the formation and breaking of chemical bonds. There are several different types of chemical reactions and more than one way of classifying them. Here are some common reaction types. However‚ if you are asked to name the

Polymerase chain reaction The Polymerase chain reaction (PCR) is a biochemical technology in molecular biology to amplify a single or a few copies of a piece of DNA across several orders of magnitude‚ generating thousands to millions of copies of a particular DNA sequence. Developed in 1983 by Kary Mullis‚ PCR is now a common and often indispensable technique used in medical and biological research labs for a variety of applications. These include DNA cloning for sequencing‚ DNA-based phylogeny

Reaction Paper Going into this course‚ my initial thoughts were that I would be learning sociology—the study of people. My first impression was‚ “how difficult of a concept could that be…studying people. I’m a people person‚ I like dealing with people; what more to it could there be?!” However‚ as I began to dive into the coursework‚ and read non-fictional examples of the complexities of people and society‚ I recognized how naïve my initial thoughts were. Several times during this course
