The Indian Slave Trade essays

The Indian Slave Trade essays My paper proposes to focus on the Indian slave trade in the colonial Southeast as a representative aspect of Anglo-Indian exchange relations generally. I am particularly interested in the years immediately preceding the Yamasee War against South Carolina, which erupted in 1715. The paper has two principal objectives in this regard. First, the paper seeks to analyze the forms of communication and cooperative action that provided the foundations for intercultural exchange. This demands that Anglo-Indian trade be viewed not simply as an economic transaction or even as an exercise in cultural accommodation and adaptation but as a form of continuing dialogue or discourse. In a previous article, published in the South Carolina Historical Magazine, I have already argued that the Indian slave trade was conducted in two phases, the first under Native American control and the second under English control. I would like to explore the mechanics of that cooperative process in more detail in my proposed paper and, equally important, begin linking the discourse that shaped the slave trade to other aspects of Anglo-Indian exchange. Second, the paper seeks to explore the aptness of current models for understanding Euro Indian relations in the South. Few southeastern scholars have attempted to apply Richard Whites Middle Ground approach to the study of Euro-Indian exchange in the colonial South. Similarly, Daniel Usners concept of a Frontier Exchange Economy, developed in his groundbreaking work Indians, Settlers, and Slaves has not been widely used beyond the Mississippi Valley region. By analyzing the Indian slave trade as a form of discourse and sharpening our focus of Euro-Indian interaction, the proposed paper hopes to re-examine the vocabulary of historical discourse as well. ...

Theoretical Yield Example Problem - Chemistry Homework

Theoretical Yield Example Problem - Chemistry Homework This example problem demonstrates how to predict the amount of product produced from a given amount of reactants. Problem Given the reactionNa2S(aq) 2 AgNO3(aq) → Ag2S(s) 2 NaNO3(aq)How many grams of Ag2S will form when 3.94 g of AgNO3 and an excess of Na2S are reacted together? Solution The key to solve this type of problem is to find the mole ratio between the product and the reactant.Step 1 - Find the atomic weight of AgNO3 and Ag2S.From the periodic table:Atomic weight of Ag 107.87 gAtomic weight of N 14 gAtomic weight of O 16 gAtomic weight of S 32.01 gAtomic weight of AgNO3 (107.87 g) (14.01 g) 3(16.00 g)Atomic weight of AgNO3 107.87 g 14.01 g 48.00 gAtomic weight of AgNO3 169.88 gAtomic weight of Ag2S 2(107.87 g) 32.01 gAtomic weight of Ag2S 215.74 g 32.01 gAtomic weight of Ag2S 247.75 gStep 2 - Find mole ratio between product and reactantThe reaction formula gives the whole number of moles needed to complete and balance the reaction. For this reaction, two moles of AgNO3 is needed to produce one mole of Ag2S.The mole ratio then is 1 mol Ag2S/2 mol AgNO3Step 3 Find amount of product produced.The excess of Na2S means all of the 3.94 g of AgNO3 will be used to complete the reaction.grams Ag2S 3.94 g AgNO3 x 1 mol AgNO3/169.88 g AgNO3 x 1 mol Ag2 S/2 mol AgNO3 x 247.75 g Ag2S/1 mol Ag2SNote the units cancel out, leaving only grams Ag2Sgrams Ag2S 2.87 g Ag2S Answer 2.87 g of Ag2S will be produced from 3.94 g of AgNO3.
