REACTIONS OF HYDROCARBONS Vanessa P. Manibpel De La Salle University - Dasmariñas ABSTRACT Five substances namely 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 and the rest retain the purplish color of KMnO4. On the other hand

Urueta English 200 PW2 H. Price 12/6/12 Essay The writer Meurer once said‚ “A great marriage is not when the ‘perfect couple’ comes together. It is when an imperfect couple learns to enjoy their differences.” (Meurer‚ 2012). My girlfriend’s mother and my father when I interviewed them‚ they took me to the same place as this quote when I read it. They told me that they help each other to have a better marriage instead of complaining and arguing about their defects. The Mother (Hinojosa‚ 2012) said

Courtship and marriage customs vary considerably from culture to culture. In Canada‚ the customs tend to reflect the diverse ethnic backgrounds in the country. Arranged marriages are rare among Canadians. Most people prefer to get to know members of the opposite sex by going out together. If two people decide to get married‚ they be-come engaged and the bride-to-be may receive a diamond ring from her fiancé’. While the parents’ permission is not required unless the bride or groom is under legal

Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are two ordinary examples which require very little description. Just a little more involved are the displacement reactions‚ with

Chemical Reactions What is a Chemical Reaction? Types of Chemical Reactions Redox Reactions Nonredox Reactions Classifying Reactions What is a Chemical Reaction? A chemical reaction is a process in which the identity of at least one substance changes. A chemical equation represents the total chemical change that occurs in a chemical reaction using symbols and chemical formulas for the substances involved. Reactants are the substances that are changed and products are the substances that are

Chemical Reactions Chemical reactions happen in almost everything around us. Reactions are very important in everyday life‚ and science. Chemical reactions are the changing of substances to other substances by the breaking of bonds in reactants and the formation of new bonds in products. There are different types of chemical reactions such as combination reaction‚ decomposition reaction‚ single-replacement reaction‚ double-replacement reaction‚ and combustion reaction. Combination

endothermic reaction happened everywhere around us. Basically exothermic and endothermic reaction is transfer energy to the surroundings and take in energy from the surroundings (BBC GCSE bitesize). If the reaction forward ，then is exothermic.If the reaction is the backwards ‚then is endothermic. When a reaction take place‚ the energy started to transfer from different object to the surroundings or take away energy from the surroundings. When temperature started to change.

“Marriages and Families” and “Diversity and Change” by: Schwartz and Scott What does marriage in the United States and other countries around the world mean? Debunking has five myths about marriage 1- The Universal Nuclear Family‚ 2-The Self-Reliant Traditional Family‚ 3- The Naturalness of Different spheres for Wives and Husbands‚ 4- The Unstable African American Family‚ and 5- The Idealized Nuclear family of the 1950’s.

The hypothesis If a chemical reaction occurs‚ then there will be indicators of a chemical change‚ was supported throughout this experiment. Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined. When stirred‚ a blue precipitate formed at the bottom of the test
