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

values that have trailing zeros only to the left of the decimal point are ambiguous and should be expressed in scientific notation. We must take note that the chemistry textbook (Silberberg 6e) states that placing a decimal point to the right of some trailing zeros (example: 300.) will make the zeros significant. However in General Chemistry‚ we do not follow this rule. If we want to write a whole number with trailing zeros we must use scientific notation to show which zeros are significant. When

Sustainability and Organic Foods People nowadays are getting into the “go green” lifestyle while others continue to live without thinking about the effects they have on the environment. Why do people go green? It can save you money‚ it is the right thing to do‚ it is healthier because there are less toxins and less illness‚ it is helping future generations‚ and it is a chance to connect with the local community and spread the word. To go along with this lifestyle and its benefits‚ catering companies

Elisa Hofmeister Kokesh Hour 3 AP Chemistry 5-29-12 The Chemistry of Coffee Green Coffee- Before coffee is roasted‚ it is referred to as “green coffee”. The green coffee is primarily made up of caffeine‚ lipids‚ carbohydrates‚ proteins (amino acids)‚ and organic acids (although inorganic acids exist in coffee as well). These groups are quite stable in the green phase‚ and it is the carbohydrates‚ proteins‚ and acids that will undergo significant reactions during roasting to produce coffee
