Acordo de livre comércio da américa do norteDricadiass
O NAFTA foi assinado em 1992 por Canadá, México e EUA para garantir livre comércio entre os países, derrubando barreiras alfandegárias. Apesar de benefícios como redução de custos e geração de empregos, também trouxe problemas como intensa migração ilegal e oposição de fazendeiros e sindicatos.
O NAFTA é um acordo de livre comércio entre Canadá, EUA e México com o objetivo de reduzir barreiras alfandegárias e custos comerciais entre os países. O acordo trouxe tanto benefícios como acesso ao mercado americano para o México, quanto malefícios como aumento do desemprego nos EUA e maior pobreza no México.
O NAFTA é um bloco econômico formado pelos Estados Unidos, Canadá e México com o objetivo de reduzir barreiras comerciais e estimular o comércio entre os países membros. O tratado busca eliminar tarifas de importação, facilitar o fluxo de mercadorias e serviços, e incentivar investimentos entre os países para aumentar a produtividade e competitividade da região.
O NAFTA (Acordo de Comércio Livre da América do Norte) é um tratado assinado em 1992 pelos Estados Unidos, Canadá e México para criar uma zona de livre comércio.

Organic chemistry: Hydrocarbons, Alkyl Halides and alcoholsIndra Yudhipratama
This document outlines topics in organic chemistry including hydrocarbons, alkyl halides, and alcohols. It discusses the reactions and properties of alkanes such as combustion and free radical reactions. Alkenes and alkynes are introduced along with elimination and addition reactions. Alkyl halides are explored with substitution reactions. Finally, the document covers alcohols and their elimination through dehydration and oxidation reactions.
Preparation of alkanes class 11-HYDROCARBONS (PART 1)ritik
Alkanes can be prepared through three main methods - catalytic hydrogenation of unsaturated hydrocarbons, reduction of alkyl halides, and decarboxylation of sodium salts of carboxylic acids. Alkanes undergo substitution reactions where one or more hydrogen atoms are replaced. They can also be oxidized through combustion which produces carbon dioxide and water, or through reactions with oxygen or air over catalysts to form alcohols, aldehydes, and other products. Higher alkanes can crack into lower alkanes and alkenes at high temperatures. Conformations of alkanes can be represented using Newman and saw-horse projections.
The document discusses several methods for preparing alkanes, including:
1) Hydrogenation of alkenes and alkynes via hydrogenation reactions.
2) Reducing alkyl halides using lithium aluminum hydride or zinc and acid.
3) Formation and destruction of Grignard reagents from alkyl halides.
4) Coupling reactions like the Wurtz reaction and Corey-House coupling.
The document contains information about 5 students' matric numbers and a passage discussing alkyl halides. It defines alkyl halides and describes their classification, nomenclature, physical properties, synthesis from alcohols and alkenes, and reactions including nucleophilic substitution and elimination. Examples are provided to illustrate key concepts and reaction mechanisms.
This document discusses the classification and properties of hydrocarbons. It describes three main categories of hydrocarbons: saturated hydrocarbons, unsaturated hydrocarbons, and aromatic hydrocarbons. Saturated hydrocarbons contain only single carbon-carbon bonds and include alkanes such as methane. Unsaturated hydrocarbons contain double or triple carbon-carbon bonds and include alkenes and alkynes. Aromatic hydrocarbons contain benzene rings. The document provides examples like propane and propene to illustrate these different types of hydrocarbons.
1) The document summarizes key concepts about ketones and aldehydes from an organic chemistry textbook chapter, including their structures, nomenclature, physical properties, reactions, and industrial uses.
2) Methods of synthesizing ketones and aldehydes are discussed, including oxidation of alcohols, Friedel-Crafts acylation, and reactions of nitriles, acid chlorides, and carboxylic acids.
3) Common reactions of ketones and aldehydes described include nucleophilic addition, hydration, imine and acetal formation, reductions, and oxidations.
This document provides information on the nomenclature, structures, and isomerism of alkanes, alkenes, and alkynes. It discusses their classification as saturated or unsaturated hydrocarbons and how they form homologous series. The key reactions of alkanes and alkenes discussed are substitution, addition, elimination, combustion, hydrogenation, halogenation, hydration, oxidation, and cracking. IUPAC nomenclature rules for naming hydrocarbon structures are also outlined.
