Spirit Burner Experiment Aim: To perform an experiment in the labs to determine the heats of combustion of selected alcohols and then to use this information and the gathered data from chemical data sources to determine trends in the longer chain alcohols. The Variables that MUST be controlled throughout the experiment are: • The height from spirit burner nozzle to the base of the water filled beaker • Air drafts around the room must be kept to minimum so as to keep the heat on the base of the

Bunsen Burner Founded by the German scientist Robert Bunsen‚ the Bunsen burner is one of the most common objects that you will find in any laboratory. The Bunsen Burner has many different parts that it is made up of. The parts that it is made of include the barrel‚ collar‚ gas flow valve‚ gas intake valve‚ and the base. The barrel is metal tube that will screw onto the base of the burner. It contains small holes called air intake openings at the bottom that allow airflow into the barrel. What

For instance‚ exercising on a daily basis can increase muscle and help manage weight. Also‚ exercise can lower cholesterol levels in blood and lower the risk of type 2 diabetes and some cancers. Moreover‚ while exercising the respiration rate increases because he/she has to expel the carbon dioxide

A Bunsen burner can be very useful if is as used properly. There are many different types of Bunsen burners but they all use a mixture of gas and oxygen to make a flame that could be used in a laboratory. To use a Bunsen burner‚ there are several critical steps. But before one starts any experiment‚ one should always read through the experiment procedures and make sure that one clearly understands all steps of the experiment. First‚ one must make sure the main gas is on. It is very important

Chemistry Lab Getting to know your Bunsen burner Part I The Bunsen or Tirrell burner is commonly used in laboratory heating operations. While the details of construction vary among burners‚ each has a gas inlet located in the base‚ a vertical tube or barrel in which the gas is mixed with air‚ and an adjustable opening or ports in the base of the barrel to introduce air into the gas stream. The burner may have an adjustable needle valve to regulate the supply of gas‚ or adjusting the

How to do a Deadly EEI in Chemistry Students: These are some hints about the requirements of a high quality Extended Experimental Investigation for the Queensland Senior Chemistry Syllabus. Guidelines given to you by your teacher should take precedence if there is any doubt. They are addressing a Year 12 EEI but will still guide you for Year 11. They refer to a hypothesis-testing EEI. What’s the purpose of an EEI? You‟ll do an EEI to research a question you have about some chemistry-related phenomena
