Experiment 1 :Alkanes&Alkenes:Combustion and action of sulphuric acid. Introduction In the study of organic chemistry‚ the organic compounds which are made up of carbon and hydrogen are called hydrocarbons. They can be gases as‚ propane‚ they can be liquids‚ for example‚ benzene‚ or they can be low-melting solids and waxes‚ for example‚ polystyrene. There are four classifications of hydrocarbons; saturated hydrocarbons or alkanes‚ unsaturated hydrocarbons or alkenes and alkynes‚ cycloalkanes‚ and

EXPERIMENT A: CIS-TRANS CONVERSION OF BUTENEDIOIC ACID PRE-LAB ASSIGNMENT 1. Maleic acid is the cis version and fumaric acis is the trans version of butenedioic acid. 2. 3. See attached paper. 4. Maleic anhydride is the compound that crystalizes in part A in the experiment. 5. HCl acts as a catalyst to break one of the carbonyl group in the maleic acid which rotates the structure to form a trans structure of the butonal acid which is the fumaric acid. And it does so by donating

education that is not an option for everyone? The idea that gender separated classrooms was once out of reach for nearly everyone in this country. Now‚ thanks to the National Association for Single Sex Public Education‚ providing a unique educational environment is not out of reach. The NASSPE‚ founded in March of 2002‚ provides a strength against groups that try to bully public school districts into removing the gender separated classrooms. The American Civil Liberties Union is one of those groups

the experiment is to study the effect of citric and buffered lactic acids on the flavour of hard-boiled sweets and the effect of acids on various flavours in high temperature applications. Introduction Materials and Methods An amount of water‚ sugar and glucose syrup of 30g‚ 100g and 70g were weighed respectively into a stainless steel pot. The mixture was then heated and removed immediately from the induction cooker after reaching the desired temperature of 145˚C. Flavours of 0.51g and acid of 1
