Concentration of a Reactant Can Affect the Rate of Reaction Aim To plan an investigation that allows me to measure the effect of increasing the concentration of a reactant on the rate of reaction. With the results generated‚ it is also hoped to draw accurate conclusions and explain the results using scientific knowledge. Introduction Some reactions are fast‚ for example neutralisation or burning magnesium in air to produce magnesium oxide. However‚ other reactions can be slow‚ for example‚ rusting of

The Inorganic Chemistry of Carbon Inorganic Carbon For more than 200 years‚ chemists have divided compounds into two categories. Those that were isolated from plants or animals were called organic‚ while those extracted from ores and minerals were inorganic. Organic chemistry is often defined as the chemistry of carbon. But this definition would include calcium carbonate (CaCO3) and graphite‚ which more closely resemble inorganic compounds. We will therefore define organic chemistry as the study

This book is the complex journey back in time to 1940’s Cairo‚ in a little dead end alley where not much happens and community is very important. The story mostly details the lives of Abbas‚ Hussain Kirsha‚ and Hamida as they break away from the community and each end up in some sort of trouble. Naguib Mahfouz clearly illustrates in this novel that relationships such as inter-community relations‚ like marriage and religion are becoming less important due to the British imperialism. The results of

Hypothesis: If I increase the concentration of NaOH from 0.5M to 1M‚ then I will see the temperature slope increase in the reaction with an increased concentration because with an increase of moles‚ the particles will be colliding more often‚ therefore increasing the probability that the proper energy and alignment will occur to create more collisions in the same amount of time. Methods: List of Materials: • 110 mL of NaOH at 1 M (10 mL per run) • 110 mL of NaOH at 0.5 M (10 mL per run) • 220 mL

activities and honors and credentials of the graduates. This report also discusses the factors affecting the employability of IA graduates and explores the relevance of the skills gained in the course of studies. The dif¬ferences of employment experiences‚ internship‚ gender and age groups were highlighted throughout the report. In the end it elicits recommendations on how IA graduates can raise their profiles internationally and enhance their employability. The findings of the study will be useful

IB Economics: Practice Internal Assessment The article “Chinese Dragon bites Local manufacture as Importers laughs last” stated that the imported products‚ majorly from China have became a threat to the local economy in Uganda. The Ugandan government have taken measure ease production on local traders by scrapping the pre-inspection fees and planning to construct industrial parks to lower the hiking cost of production of local products. Chinese products are cheaper and more competitive comparing

ECONOMICS Economic Problem * Unlimited wants‚ limited resources Economic Systems * Questions to answer: 1. What to produce? 2. How much to produce? 3. How to produce? 4. For whom to produce? * Criteria to classify economic systems 1. Productive resources owned by private individuals (private sector) or government (public sector) 2. Role of market forces of demand and supply in allocating resources‚ determining prices‚ distributing incomes 3. Role of government in production

found that‚ in acidic pH environment‚ the reaction rate of starch being broken down by alpha amylase is less than that of the reaction rate at a neutral and slightly basic pH environment. This finding partially supports our hypothesis. The spectrophotometer readings in our experiment measured the absorbance of 3-amino-5-nitrosalicylic acid‚ a colored molecule formed after dinitrosalicylic acid (DNSA) has reacted with the products of the enzymatic reaction or the simple sugars. Therefore‚ the absorbance
