Investigating The Rate Of Reaction Between Marble Chips And Hydrochloric Acid Planning I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction. I will use concentrations of 50cm3 using different volumes of water and acid. Introduction I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. This is the word equation for my investigation

The name of the artwork I viewed at the Metropolitan Museum of Art is‚ Marble statue of Dionysos leaning on an archaistic female figure. The statue was created between 27 B.C to A.D 68‚ which was during the Augustan or Julio- Claudian period. The original artist is unknown‚ but Vincenzo Pacetti restored it. This artwork caught my attention because the size of the sculpture was different from other artwork in the room. The work is guiding viewers’ attention to a primary focal point‚ which is the bend

many marbles the wet tissue can hold. Students conducted this experiment to determine if higher priced tissues can hold an increased amount of marbles. This experiment was a blind study‚ with the supervisor of this investigation withholding information of which brand is which and their costs. At the end of this experiment‚ it was concluded that the higher priced brand‚ Puffs‚ held the most marbles at an average of 41 marbles. Purpose: Does higher- priced tissues’ wet strength hold more marbles? Background:

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise
