I was able to identify all the liquids in our sludge but only about half of our solids mainly because we only started working at a good pace towards the very final days of sludge. We didn’t identify any gases because there wasn’t any in our sludge. We only had three liquids in our sludge. We were able to get at least 10 ML. of liquid A and Liquid B. We had about 6 ML. of liquid C but on day #18, Monday, May 20, all our our liquid C was gone. I’m not exactly sure what happened like if the test…

Concorde The one and only supersonic passenger airplane that existed up until now was the Concorde. The Concorde belonged to both the British Airway and the Air France and was released on 21st January 1976. The Concorde flew with a speed of 2172 km/h and had a takeoff speed of 402 km/h. It used the most powerful pure jet engines flying commercially (Celebrating). Concorde was 62 m long and still increased between 15 to 25 cm due to heating of the airframe as well as a wing span of about 25 m…

I have always been interested in climate change, in the same line as global warming. I would like to learn more about how the communities and big businesses is causing damage to the climate. I remember one of my friends told me that if you leave your water running outside in your lawn you will be fined, which came as a shock to me.

Renewable energy is the clean power of the future. Mankind is running into a dead end and must act now. The world is filled with variations of power that are rapidly depleting fossil fuels, the average population must understand how these fuels are obtained, what the long term effects of using these fuels has on the world, and how the human race can move forward by using different variations of renewable energy, whether it 's for housing or transportation purposes. "Fossil fuels are an…

CHAPTER TWO LITERATURE REVIEW 2.1 Basic Concepts of Land-Use and Land-Cover Change According to (FAO (Food and Agriculture Organization), 2000; Gregorio, 2005) land cover refers to the biophysical cover of the earth surface or land for instance vegetation cover such as forest, shrub/bushland, and grassland and water. Whereas land cover can be defined as the attributes of the earth’s land surface covered by vegetation, desert, water bodies like lake, sea, ocean, bare soil and ice (Chrysoulakis…

Practical Title: The pros and cons of cell signalling experiments: risk assessments Aims: The aim of this experiment was to identify the risks associated with working in a laboratory by carrying out a risk assessment. The risk assessment instructed us how to safely work in a laboratory while being aware of these risks and what procedures to carry out if an accident happened in the laboratory. Methodology: Prior to the beginning of the risk assessment, laboratory coats, nitrile rubber gloves…

Tin is a Chemical element its symbol is Sn. Its location on the periodic table of elements is period 5 group 14. Its atomic number is 50 and the atomic weight is 118.71. It has 50 protons, 50 electrons, and 69 neutrons. Tin is a solid, ductile, malleable, silvery-white metal. Tin melts at a low temperature of about 232 °C (450 °F). Tin resists corrosion from water, but can be attacked by acids. Around 5000 years ago, humans first began mining and incorporating tin with copper to create bronze…

in succession before the precipitate reaches the substrate. D) When the precipitate reaches the substrate, nucleation and the growth of metal oxide thin films on the substrate take place. E) Finally, the growth of the nuclei leads to the formation of continuous thin layer of metal oxide. Fig. 2.3. Mechanism of thin film formation by spray pyrolysis…
