Enzyme is a type of protein that speed up the rate of reaction of living organisms. Enzyme also acts as a catalyst for specific chemical reaction by converting a specific reactants into a specific product. The enzyme activity will also be affected by temperature and pH value. In this experiment‚ enzyme was placed in carbohydrate solution at different temperature to identify unknown carbohydrate solution. The enzyme that involved in the reaction is salivary amylase. The action of amylase on starch

DEFINITIONS OF OXIDATION AND REDUCTION (REDOX) This page looks at the various definitions of oxidation and reduction (redox) in terms of the transfer of oxygen‚ hydrogen and electrons. It also explains the terms oxidising agent and reducing agent. Oxidation and reduction in terms of oxygen transfer Definitions • Oxidation is gain of oxygen. • Reduction is loss of oxygen. For example‚ in the extraction of iron from its ore: [pic] Because both reduction and oxidation are going on side-by-side

Thomas Chares Hope. Strontium was first isolated by English Chemist Sir Humphry Davy in 1808. How and where is the element found?- Strontium commonly occurs in nature and forms up to 0.034 of igneous rocks and is also found I the form of the Sulphate mineral Celestine (SrSO4) and Carbonate Strontianite (SrCO3). The main mining areas for Strontium is in areas of UK‚ Mexico‚ Turkey and Spain and the world production of strontium ores is approximately 127006 kg every year. Strontium can also be

studies showing 90MPa achievable in as little as 6 hours (Gourley et al. 2011). In addition‚ GPC has a higher tensile strength which in some applications may make steel reinforcement obsolete. GPC properties such as low shrinkage and improved acid‚ sulphate and fire resistance‚ give it improved durability. This therefore makes GPC a viable replacement for project applications such as sewerage systems‚ corrosive environments and radioactive and hazardous material containment. TABLE OF CONTENTS
