process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

to discoveries of new life‚ space exploration has led to much advancement‚ including ones that we use in our daily lives. An example would be those comfortable beds that are made of memory foam. Unlocking the mysteries of what’s beyond or planet is the solution to many problems we have here on earth. The possibility of finding new resources and life in space‚ overpopulation on planet earth and finding a new source of fuel are just a few of many reasons to encourage space exploration. Planet earth

of the astronauts’ life in space was to be recorded for future examination and there was little left to chance. Virtually every minute of each day was spelled out by the flight control directors on the ground and the rigid timelines were to be followed to the letter. The astronauts were to conduct experiments on themselves (exercise) as well as other scientific fields (solar astronomy‚ botany‚ biology‚ metals processing NASA not only wanted to study the experiments given to the astronauts but

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

travel to space and back. But today it is happening and it is called space tourism. Arnold Schwarzenegger’s movie‚ ‘Total Recall’ had space tourism as a central theme. Such tourism however is the privilege of the hugely wealthy for it costs a lot of money. On April 28‚ 2001‚ Dennis Tito‚ a California-based multi-millionaire became the first paying space tourist. He paid $20 million for the trip! Tito travelled on a Russian Soyuz capsule launched by an American company called Space Adventures
