Discussion The reaction through which 4-mrthaoxyacetophenone is converted to 4-methoxybenzoic acid is a haloform reaction. This reaction involves two distinct stages that occur in the same environment. The first stage occurs through the based-catalyzed halogenation of the ketone that forms a trihalo ketone. First‚ the bleach is transformed into chlorine and hydroxide ions through the following reaction: Then‚ the hydroxyl is able to attack the rather acidic (pKa ~ 20) α-hydrogen of the ketone

ction paper Reaction Paper The play entitled ‘’Insect Talk’’ focused on the Global Warming issue and how it affects our ecosystem especially to insects. After watching this play‚ some thoughts about the effects of global warming enter to my mind. The negative effects of global warming are numerous‚ and we hear about them all of the time. As the earth warms‚ insects can more easily migrate to new areas. This creates a huge problem for the local environments‚ because the animals and other insects

economic growth‚ poverty reduction‚ and preservation of the environment‚ as clearly shown by the experience of the other East and Southeast Asian countries. Economic growth is facilitated by higher private and public savings – owing to slower growth of the youth dependents – required for investment in human capital (i.e.‚ spending on education and health per person) and infrastructure. Slower population growth combined with faster economic growth leads to significant poverty reduction‚ human development

What is this rhetoric referring to? This rhetoric is referring to an economic purpose of schooling‚ particularly the Human Capital Theory. Joel Spring‚ in his book American Education (2016)‚ defines Human Capital Theory is that with investment in education within a community‚ that community will have more wealth returned to that community (p. 90). Human Capital Theory dates back as far as the 19th century‚ since then it has been used to justify political and economic goals of schooling. In this paper

Damien Hirst is no stranger to playing with morbid themes based on death‚ human self-destruction‚ and a somewhat forced mortality. “You try to avoid death‚ but it’s such a big thing that you can’t. That’s the frightening thing‚ isn’t it?” He often stresses that people are generally too concerned about what’s going on in between- nobody takes into consideration the start or the end‚ and just are happy to remain floating somewhere in the middle of these two points. In his early career he spent time

Rates of Reaction Coursework Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate. Both of the chemicals are clear solutions and they react together to form a yellow precipitate of sulphur‚ the equation for this reaction is: Na2 S2 O3 + HCL‚ H2 O + NaCL + SO2 + S Sodium Thiosulphate + Hydrochloric

INDIGENOUS PEOPLE REACTION PAPER WOW! After the symposium‚ I realized how lucky I am to be in a concrete house‚ not worrying if the strong wind will take it with all its might; to live in a more comfortable house with comfortable clothes on. Indigenous people’s always stressing the hell out of them searching for food everyday‚ they can’t even apply for a stable job here in the city or at least away from secluded areas where they live. On the other hand‚ I salute them for they’re always active
