REACTIONS OF HYDROCARBONS Diane Cate Satsatin Biology Student‚ Biology Department College of Science‚ De La Salle University-Dasmarinas ABSTRACT Five substances which are Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively

Investigating The Rate Of Reaction Between Marble Chips And Hydrochloric Acid Planning I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction. I will use concentrations of 50cm3 using different volumes of water and acid. Introduction I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. This is the word equation for my investigation

include a purpose‚ procedure‚ data/observations‚ all reactions and side reactions written out with qualitative data beneath each product and reactant except H20‚ and a summary. The purpose of this experiment is to observe the qualitative aspects of a series of reactions involving copper. Procedure 1.Measure about 1g of solid copper. 2.Place Cu in Erlenmeyer flask and place flask under fume hood. 3.Add dropwise 15M HNO3 until solid copper is completely reacted. 4.Place flask in water bath.

Coupled Reactions Louella Rose E. Tan‚ Frances May L. Coralde Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines Results and Discussion A combustion reaction is a reaction that liberates heat and light. Magnesium is a stable element and reacts violently with evolution of much heat and light. The reason the magnesium burned in carbon dioxide was because it combined with the oxygen in the CO2 leaving elemental carbon behind. CO2(g) C(S) + O2(g)

Investigation Srategy I am ivestigating the reaction of sodium thiosulphate and hydroclohric acid. sodium thiosulphate(aq) + Hydroclohric Acid (aq) --> Sodium cloride (aq) + Sulphur Dioxide (g) + Water (l) + Suplhur (s) Na(2)S(2)O(3) + 2 HCl --> 2NaCl + SO(2) + H(2)O + S The finished reaction of the 2 clear liquids is cloudy.I will use this change from clear to cloudy as an indicator as to when the reaction is finished. By using this change ‚ i can see the effect of changing other factors

of those who were trapped under the Chilean copper mine had to consider not one day but even two months. According to The New York Times Company(2014)‚ “On Aug. 5‚ 2010‚ a gold and copper mine near the northern city of Copiapó‚ Chile caved in‚ trapping 33 miners in a chamber about 2‚300 feet below the surface”. At this time no one knew the well being or the nature of the situation that happened at the copper mine. During this time communication between employers‚ families’ members’ involved‚ trapped

Reaction on Climate Change The Philippines has been considered as a highly vulnerable to current (natural disasters)‚ as well as future climate-related risks due to its geographical location and physical characteristics. It lies along the Western Pacific Basin (a generator of climatic conditions such as monsoons‚ thunderstorms‚ Inter-Tropical Convergence Zone‚ typhoons‚ among others) making it a path of an average of 20 tropical cyclones annually‚ nine of which makes a landfall.

Volume 1‚ Issue 1 By: Michelle Mitchell 12/04/2010 Final Reaction Paper Which would you recommend for Desktop Publishing? “I loved working with Microsoft Publisher‚ rather than Microsoft Word. Publisher was so much more fun to work with. It had a lot more of a variety to work with. For instance‚ it has different page designs and layouts. Also‚ in my opinion‚ Microsoft Publisher is a lot easier to work with. I find myself getting confused and not knowing where things are in Microsoft
