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

Prehistoric Times - Beginning of the Christian Era (Black Magic) * 1700 BC King Hammurabi’s reign over Babylon In ancient Babylon King Hammmurabbi began to classify metals such as gold ‚ iron‚ and copper. He also gave certain materials higher value than others‚ depending on the potential of the material. Known metals were recorded and listed in conjunction with heavenly bodies. 430 BC Democritus of ancient Greece Democritus and the atom: c.420 BC In the late 5th century BC Democritus
