UTAR FHSC1134 Inorganic Chemistry Trimester 3 Experiment 1 ________________________________________________________________________ Title: Investigating the Properties of Period 3 Oxides Aim: To examine the oxides of Period 3 elements and describe their structure and bonding. Introduction: Generally‚ there are oxides of metals and non-metals. Metals burn in oxygen to form basic oxides while non-metals form acidic oxides. Structurally‚ they are covalent or ionic compounds. You are to

The ‘Experiment’ by Dr Haskell portrays the unusual experiment that he conducted to compare his bare body and a Chickadees body in harsh freezing conditions. He decided to investigate it further because there was no logical explanation for a tiny bird to be able to survive in such conditions. He related his astonishment to the Bergmann’s rule‚ which states that larger animals will be found in colder climates and smaller animals will be found in warmer climates. Haskell found that the Chickadees

The purpose of this experiment was to test the tonicity of potato cells. The potato cells were placed in different test tubes with water and were left there for 15 minutes. The percent change in mass is then used to determine if the cells lost or gained water‚ therefore determining the tonicity of the cell. Although it was a brief short time‚ the final results showed that the more water the potatoes were placed in‚ the more hypotonic the potato becomes. Tonicity is stated to be the state of a solution

Abstract An experiment is conducted to prepare soap and thus‚ to compare the properties of the prepared soap and synthetic detergents which are precipitation‚ emulsification and cleaning abilities. It can be concluded that soap has the properties if emulsifying oil whereas detergent has not. The abilities of forming precipitates can be seen clearly in soap solution whereas detergent forms no precipitates at all. The experiment is completed and successfully conducted. Introduction

Photosynthesis Experiment Introduction Photosynthesis is a process used by plants‚ making inorganic molecules into organic molecules (food) using sunlight. Carbon dioxide + Water (mainly from rain) Glucose + Oxygen From this process‚ carbon dioxide comes from environment. Glucose‚ as a product is used to make energy for growth. Lastly‚ the oxygen is a waste product in this chemical reaction‚ which become part of the Earth’s atmosphere. At this experiment‚ carbon dioxide and water

At first we wanted to figure out if one gender had a better memory than the other‚ but then we also wanted to observe whether or not their memory showed better results when the objects were related to their gender. Therefore‚ the hypothesis we constructed was: If

The wheelchair experiment introduced me to a world that I have never known. I have never been in a wheelchair or been affected by any form of hearing‚ visual‚ or physical disabilities. So‚ this experiment caused me to really think about how the layout of a space‚ weight of doors‚ etc. could affect someone. While using the wheelchair‚ I felt as if I was in the spotlight every time I entered a room or crossed paths with a group of individuals. People would look on as I posed in the wheelchair and give

Should we use animals for experiments? (against) The question is‚what it means to use animals for experiments? It means‚ the investigators and doctors whose are producing medicines they have to test is first‚somehow‚to see how is the effect of the medicine.This “somehow” means the animals.Moreover I haven’t said anything about testing new products like cosmetic products‚make-ups‚sprays. In my opinion‚the animals are different‚they body and organism are different.For this reason the scientists

To explore the concepts of Utopian theory‚ both political and social‚ one must first engender a concrete definition of what Utopia means. Sir Thomas More‚ the original creator of the term Utopia‚ signifies it as “no place”. However‚ More’s clever play on words seems ultimately to suggest that ”no place” is just no place right now. That is to say that Utopia is “an ideal place that does not exist in reality” yet (Murfin and Ray 529). The theoretical and literary genres of Utopianism which came in
