solution NaOH is a very corrosive chemical and contact with it can cause burns to body tissue and possible eye damage. Can irriate the lungs and can cause permanent lung damage. also contact with water can generate enought heat to ignite combustibles. 2. In your own words‚ briefly explain the terms below. Copied answers will receive zero points. a. equilibrium state When a chemical reaction is equal. when the products and reactients are at equal rates b. the effect of formation of a complex a complex

to determine the molarity of NaOH‚ we rinsed a burette with about 5ml of water and another 5ml of NaOH to prepare it for the experiment. We then measured exactly 25ml of the prepared KHP from the previous part into a 250ml Erlenmeyer flask and added 2 drops of the indicator‚ phenolphthalein. Next we filled the burette with the approximately 0.1 M NaOH so that our initial volume will be 0.0mls. We then started our titration by carefully pouring a little amount of the base into the prepared 25ml of

“I want you to run and not stop until you are safely in the car‚” Fancy said‚ leading the way. When they were safe‚ Fancy stared at the one-room shack as tears poured down her face. " I wonder what happened to Momna and Lisa? I hope they are okay‚” she whispered. “I am ready to leave‚” she said‚ telling Samuel to drive through town to the bungalow. Fancy asked him to slow down as he drove past the swamp. He pointed toward two large gators as they emerged from the swamp and headed toward the road

LAB 10: NAME: DaeNia La Rodé DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without

Lab Report Factors That Affect Enzymes Reaction Rate Name of lab: Effects of temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity Introduction: Enzymes are the most important types of proteins‚ they act as catalysis (speed up chemical reactions). If enzymes didn’t exist‚ biochemical reactions would act to slowly and they couldn’t keep up with the metabolic functions. Enzymes have a three-dimensional structure that is really complex. This structure consists

making the bacteria take on various phenotypic characteristics. Background Information: Genetic transformation is one of the most important processes in biotechnology. Essentially‚ genetic transformation involves the process where a cell (in this lab‚ a bacterial cell) takes up foreign DNA from its surroundings and incorporates it into its own DNA. This gene transfer is accomplished with the aid of a plasmid‚ a

Chapter 16 Notes The heart lies in the mediastinum and is surrounded by a doubled layered membrane called the pericardium. The outer most layer of the pericardium is called the fibrous pericardium‚ which anchors the heart to surrounding structures. The inner layer is called the serous pericardium and is composed of two layers. The outer portion is called the parietal pericardium‚ the inner portion is called the visceral pericardium (epicardium). Epicardium- outer most layer of the heart wall

Amazon Warrior Women 1. Who were the Amazon Warrior Women? A group of Women warriors thought to have settled around the Black Sea. Who mated with vanquished foes and only kept the female children they bore. 2. Where are references to the Amazons found? The first account was found in Homer’s ILIAD‚ an account of the Trojan War. Greek historian Herodotus talked about a group of women warriors in his writing around 5th or 6th century B.C. 3. What evidence is there that the Amazons may have existed

BIOLOGY HSC NOTES MAINTAINING A BALANCE • Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates. Enzymes are protein molecules that allow the body to engage in chemical reactions‚ such as metabolism. There activities can be catalytic (being able to control the rate of either increasing/decreasing chemical reaction) Enzymes have a specific shape‚ and this shape must be intact‚ otherwise the effectiveness
