Chemical Reactions and their Classifications 26 October 2012 Abstract: Ordinary laboratory ware was used to determine how many of what type of chemical reactions occurred. This yielded three decomposition reactions‚ four substitution reactions‚ and three metathesis reactions. Introduction There are many different types of chemical reactions in the study of chemistry; A composition reaction (also known as synthesis) is defined as the reaction that occurs when two single compounds combine in

Succession is the measurable process in which a community changes and thus the community as a whole is altered (Friedman 2017). To study succession‚ one must use one of the following methods: to observe any patterns that occur‚ to conduct experiments that manipulate specific variables in a community‚ or to construct a model that may undergo succession. One example of an experiment that measures microbial succession was an experiment observing changes in traditional Chinese soy sauce over time (Sulaiman

direct and circumstantial evidence. One of the evidence markers weighs significantly heavier than the other‚ direct evidence being much more substantial than any circumstantial evidence. However‚ circumstantial evidence may build an entire case. Direct evidence is defined by Criminal Investigation Basic Perspectives‚ Eleventh Edition as an eye witness who through one of the five senses witnesses the crime committed. To further breakdown this definition of direct evidence‚ one may turn to Merriam-Websters

Why are Americas rules of evidence more restrictive than those established by other countries? America’s rules of evidence are more restrictive because unlike some countries we have Constitutional protections that safeguard individual rights. An example of this would be the Supreme courts determination that a state rule requiring that a defendant wanting to testify in a criminal case must do so before the admission of any other defense testimony is a violation of the Fifth and Fourteenth Amendment

Name: Tom Flannigan Title: Physical and Chemical Properties Purpose: To investigate the chemical properties of pure chemical substances. To investigate the physical properties of pure chemical substances. Procedure: For this lab we used four test tubes and poured equal amounts of a substance in each test tube. We then observed the color and odor. We then heated the substance and recorded the observation. The next tube we added cold water and observed the effects‚ then we heated it

rest of it is converted into energy (according to Einstein’s law: E= mc2) and is sent to earth. That makes the light of dawn‚ the heat of summer‚ and the fading glow at dusk. The next element I will discuss is cerium. (The only reason I am doing this one is because it is use in flint and steel strikers to make FIRE‚ and I love fire). On earth‚ cerium is almost as abundant as copper and is very inexpensive. It is mainly use in the form of cerium oxide which is use for grinding and polishing glass

positively and negatively. The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature (El-hilali et al.‚ 2012). The most eye catching factors that we tested for their impact on enzyme activity involved change in pH‚ temperature‚ boiling extract‚ and the
