Write down the aim of your Investigation. To investigate the effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid. Briefly describe your Preliminary Experiment and include your results. Explain how these results have helped you plan your main experiment (p8b). An increase in concentration will lead to an increase in the rate of reaction because there will be a greater number of particles per unit/cm3. The particles will be closer together and

for the poor‚ and other social spending programs‚ relying mostly on the private sector to finance important infrastructure projects. Weak tax collection‚ exacerbated by new tax breaks and incentives‚ has limited the government’s ability to address major challenges. The AQUINO administration has vowed to focus on improving tax collection efficiency‚ rather than imposing new taxes‚ as a part of its good governance platform. The economy still faces several long-term challenges‚ including reliance on

Introduction Comprehensive Agrarian Reform Program (CARP) In 1988‚ the government launched the CARP through Republic Act (RA) 6657‚ seeking the distribution of some 10M hectares of agricultural lands to farmers and regular farm workers. The government also directed specific agencies to provide the required support services and other factors needed to ensure socio-economic upliftment of the lives of the beneficiaries through Executive Order (EO) No. 229. The DTI’s participation in the CARP was

Acid Rain is a type of air pollution‚ which is formed when oxides of sulfur and nitrogen combine with atmospheric moisture to yield sulfuric and nitric acids‚ which may then be carried long distances from a source before they are deposited by rain. This pollution may also take the form of snow‚ fog‚ or a dry form of precipitation. Acid rain is currently a subject of great controversy because of widespread environmental damage‚ for which it has been blamed‚ including eroding structures‚ injuring crops

experiment the objective was to perform a Diels-Alder reaction using cyclopentadiene and maleic anhydride to synthesize the product‚ cis-Norbornene-5‚6-endo-dicarboxylic anhydride. The Diels-Alder reaction is one of the most important reactions in organic chemistry and was first investigated by Otto Diels and Kurt Alder in Germany. It is a [4+2] concerted cycloaddition reaction which involves a diene and a dienophile. The Diel-Alder reaction are mainly used for creating new carbon-carbon bonds‚ mostly

Acid-Base Extraction: Separation of an Organic Acid‚ Base and a Neural Compound Introduction/Background Acid base extraction is a widely used commercial method in separating acids‚ bases and neutral compounds. This is concept is based on several physical properties of the compounds‚ such as boiling point‚ melting points and solubility. The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present‚ such
