The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate of consumption of A = -[pic]rate of

PPE is a vital part to an investigation; not only for preserving the crime scene but also ensuring the safety of the forensic scientist. PPE comes in all shapes and forms‚ ranging from latex or nitrile gloves‚bubble suits‚ face masks‚ eye protection etc. In this lab‚ the group investigated the living room where a suspected stabbing occurred (living room 1). The PPE required for this investigation included: latex gloves‚ disposable filter masks‚ and shoe covers. Each piece of PPE was significant to

For this assignment‚ you will be designing a lab to investigate factors that affect the rate of a reaction. You are not required to conduct the experiment‚ but it may be beneficial to do so if you can acquire the materials needed for your design. The reaction that you will be investigating is the reaction that occurs when an Alka-Seltzer tablet is placed into a given amount of water. Alka-Seltzer is an over-the-counter antacid and pain relief medication that is dissolved in water before it is

Research Paper: Crime Scene Investigation (first draft) If a murder‚ a homicide and or a suicide occur‚ the crime scene investigator(s) collects the clues and evidence that will be analyzed by the forensic scientist(s) which can lead them to their suspect(s). The purpose of a Crime Scene Investigation is to help victims find justice. When a crime has been reported‚ the responding officer and/or detective have to note the dispatch information such as address/location‚ time‚ date‚ type

Homicide Investigation More work goes into a homicide investigation than what the media alludes to. Television shows like Law and Order‚ and CSI show an over glorified series of basic investigations as well as highly dramatic interrogation in which each homicide case is solved within a one-hour episode. In reality‚ a homicide investigation is 20 times more complex than what is aired on prime time television. Cases can take years to solve‚ and a large number remain open indefinitely. From start

pulled off a sheet from one of the chairs. It smelled dirty and musty. I started to uncover other things‚ like paintings and other furniture. Yet out of all the things I found‚ my two favorites were a handmade grandfather clock and an old bookcase! I like the grandfather clock because it filled the creepy silence of the house with a slow‚ yet graceful “Tick-Tock.” The bookcase I liked because the books make a beautiful display even with the gritty and dusty covers. The crinkly pages were fragile

In criminal investigation there are many methods of inquiry. Most of these methods can be placed in one of two categories: methods that help to reconstruct the past or methods that help to discover or create a new idea or theory. Some examples of these methods are induction‚ deduction‚ classification‚ synthesis and analysis. Induction is a process that starts out with a specific observation and works backward toward a general conclusion. Induction has been compared to the formation
