Alloy - An alloy is a substance made by melting two or more elements together‚ at least one of them a metal. An Example: Examples of alloys include brass‚ bronze‚ 14k gold‚ and sterling silver. covalent bond - A covalent bond is a chemical link between two atoms in which electrons are shared between them. An Example: There is covalent between the oxygen and each hydrogen in (H 2 O). Each of the bonds contains two electrons - one from a hydrogen atom and one from the oxygen atom. Both atoms

is a chemical change‚ but it is actually a physical change. This is because the pieces that caused the reaction are still there‚ but they have just been rearranged. This also means that changing some of the factors in this experiment might cause another physical reaction to occur on a smaller or even larger scale.(Science Buddies) What you see when mentos are put into diet coke is that the coke spews out of it’s container once contacted with the mentos. But have you ever wondered why this reaction

Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which

obtained evidence The exclusionary rule is the rule that defines the circumstances in which a court will exclude evidence on the grounds that it has been obtained in violation of the accused’s constitutional rights. Traditionally the common law did not have an exclusionary rule. The court allowed evidence to be admitted that had been obtained through the use of illegal means‚ for example‚ searching a dwelling without a search warrant‚ any evidence obtained is an illegal evidence‚ but this was allowed

Good Moring‚ I am expert witness VaShanti Lawrence. I was called to testify about hair. Also I am here to inform you about the forensic hair analysis and explain why it is considered calls evidence. I am going to prove that the suspect Colin Ross’s hair does match the hair found at the crime scene. This is a diagram of the basic structure of hair a hair from the crime scene‚ or one found on the victim‚ will be microscopically compared with a number of hair samples from the suspect. There are

9. Piper Alpha video review The Piper Alpha’s tragic chain of events occurred because of a number of safety procedures were not met or implemented. The almighty dollar was given preference over the safety of hundreds of lives. We found a number of unsafe situations that could have been avoided if the right Safety management system was in place. These are our findings. 1. The oil rig recently introduced a new gas pipeline in the weeks leading up to the disaster. The rig wasn’t designed to be a gas
