central role to establish the basic concept in coordination chemistry while reaction kinetics of coordination compound is known as the area of continuing intense research activity. The mechanism of the reactions of coordination compounds relevance to enzyme reactions where the active site is being involve in coordination to a metal ion. PROCEDURE: (A) Preparation of Trans-Dichlorobis(ethylenediamine)cobalt(III) chloride 1. About 16g of cobalt(II)chloride hexahydrate is dissolved in 50ml of distilled

# Now You See It – Copper Cycle Lab The purpose of the lab is to discover what happens when someone executes a series of procedures‚ beginning with copper metal. What is done | What is observed | 1. Started with copper‚ Cu (s). | reddish‚ brownish‚ orange-ish‚ powder-like | 2. Added nitric acid‚ HNO3 (aq). | acid turns blue and smells like chlorine. | 3. Added water‚ H2O (l). | stayed the same | 4. Added sodium hydroxide‚ NaOH (aq). | changed consistency‚ gel-like | 5. Heated the

Studying the Rate of Reaction of catechol oxidase and how it affects pH levels Introduction: In this lab‚ we studied the activity of an enzyme that is found in fruits and vegetables called catecholase or catechol oxidase. An enzyme is a protein molecule that is a catalyst. Catechol oxidase is the enzyme in fruits and vegetables that turns them that undesirable brownish color; also commonly referred to as bruising or bruised. When walking through your regular grocery store and you find yourself in

Filtration is what is used to remove solid particles and they can be removed by passing through a liquid and gas. The information above is very important because it is exactly what everything in this lab will be about. It explains in detail what every single little definition and important

see his reflection. We also exposed the fish to many others to see if the behavior was the same or different when placed next to: a goldfish‚ a female Betta fish‚ and a zebra fish. My hypothesis was supposed by this experiment and it was observed that the Betta fish was disturbed by his reflection in the mirror but his aggressive behavior decreased rapidly when other tanks‚ containing different types of fish‚ were placed next to his. Introduction Ethology is the study of animal behavior

apply that understanding of the microbial world so that the benefits to the Earth and humans are known(6). This lab specifically does not require the knowledge of what each organism does when introduced to another living organism‚ like a human. Figuring out the type of bacteria could help with further experiments. The idea of the unknown bacteria lab is to show

Also‚ many drugs produced contain drug classes that can inhibit the function of mitochondria by preventing or altering a stage in ATP production in the Krebs cycle or electron transport chain or acting as an inhibitor of an enzyme that carries out a certain reaction in citric acid cycle or ETC (Dykens and Will‚ 2007). These drugs are therefore pretested

lipase‚ an enzyme that breaks down fat. The fat hydrolysis test was positive‚ showing K. pneumoniae produces lipase and can break down fats. The indole test was performed to determine if our bacteria can break down tryptophan via the enzyme tryptophanase. Our indole test came back negative‚ meaning K. pneumoniae does not produce tryptophanase and does not break down tryptophan into indole‚ ammonia‚ and pyruvic acid. The urea test was performed to determine if urea is hydrolyzed via the enzyme urease

wouldn’t go as far and the direction or trajectory of the cannon ball would be a curved line going down. Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground & a stool. With this experiment we will see if shooting from the ground gets the plastic ball to travel farther
