The materials we used for this project were the fruits and vegetables and an amp meter to measure the current flow in them. We learned the difference between electrical charge and conductivity. We measured the electrical charge first and the conductivity second. First‚ we looked for current flow in each of the fruits and vegetables using the micro amp scale on the meter. Second‚

Experiment 9 : The effect of substrate concentration on enzyme activity Objective To find out the relationship between the substrate concentration and the rate of reaction by determining the number of bubbles produce Hydrogen peroxide (H2O2) is a by-product of biochemical metabolism. An accumulation of hydrogen peroxide can be deadly‚ so it has to be decomposed. One of the decomposing factors is an enzyme called Catalase. Catalase breaks hydrogen peroxide into water and oxygen. The chemical

Properties of Different Bonds An ionic compound forms from a nonmetal and metal element. A covalent compound is formed by two non metal elements. A metallic compound is formed by two metal elements. Metallic compounds have generally high melting points‚ are loose and flexible with their electrons‚ conduct electricity well‚ and have low solubility in water. Ionic compounds are generally crystals‚ have a high melting point‚ and usually have high solubility in water and conduct electricity well when

Question 1 Electromagnetic radiation behaves both as particles (called photons) and as waves. Wavelength () and frequency () are related according to the equation where is the speed of light (). The energy ( in joules) contained in one quantum of electromagnetic radiation is described by the equation where is Planck’s constant (). Note that frequency has units of inverse seconds ()‚ which are more commonly expressed as hertz (). Part A A microwave oven operates at 2.40 . What is the wavelength

Current and Non-current Assets Without assets‚ businesses could not function. In order to show how much a business owns assets are used in accounting to clearly define the positive side of a balance sheet. Current and non-current assets are not only cash‚ but also monies which will turn into cash in the future. This includes receivables‚ properties‚ work in progress and buildings. This paper will define current and non-current assets‚ differentiate between the two‚ the order of liquidity and

Sustainable Chemistry Terry Collins* Chemistry has an important role to play in achieving a sustainable civilization on Earth. The present economy remains utterly dependent on a massive inward flow of natural resources that includes vast amounts of nonrenewables. This is followed by a reverse flow of economically spent matter back to the ecosphere. Chemical sustainability problems are determined largely by these economy-ecosphere materials flows (see the figure‚ below)‚ which current chemistry education

Clinical Chemistry When people consider their careers in the health care field‚ most of them would think about being a physician‚ a nurse or a surgeon. Individuals with interest in the health care field are not aware of clinical laboratory science. I am one of those individuals who don’t know much about clinical laboratory science before. After taking the class “Introduction to Clinical Laboratory Science”‚ I start to realize that clinical laboratory scientists are just like other health care members
