CH.15 Review Questions Growing Tensions Between North and South 1. How did the North and the South differ in the 1840s? In the 1840s‚ the North and the South differed because the North had slaves and the South didn’t. 2. How did Southerners react to the Wilmot Proviso? The way the Southerners reacted to the Wilmot Proviso was that they were mad because the government was taking what Southerners thought was their property. 3. What was Stephen A. Douglas’s role in passing the

Discussion and Conclusion In this lab‚ a submarine Adventure: Density Saves The Day‚; I had made many of the calculation for the best result of the lab. My calculations section contains: the volume of the unknown metals‚ where I figure out the volume of each metal so that I will be able to determine its density in order to find its identity; the density of unknown metals‚ where I figure out the density of each metal so that I will be able to determine its identity; percent error between known

9/17/13 The Density of Metals Lab BACKROUND: Density is a constant relationship between the mass and volume of a specific type of matter. Measurements of both mass and volume can be obtained for a metal sample. The relationship can be shown graphically by plotting the volume of a sample on the horizontal x-axis and the mass of the sample along the vertical y-axis. Plotting the values for several samples‚ a linear relationship can be seen for a density (slope=density). PURPOSE: During this lab‚ you will

Hamza Aziz General Chemistry I Lab 09/12/2007 Lab 7 Density of Sprite and Diet Sprite Abstract: The density of regular Sprite was found to be 1.037 +/- g/mL. compared to Diet Sprite which was 0.9965 +/- g/mL. Among the three volumetric glassware Pipette was most precise (ó=0.0016 g/mL). Burette was the second best (ó=0.0023 g/mL) and graduated cylinder was the least precise (ó= 0.007 g/mL). Density was found to be intensive property. The slope of the graph of mass against volume was 1.05

Percent Water in a Hydrate PURPOSE To determine the percent water in a hydrate sample. INTRODUCTION Many substances contain water molecules as a part of their crystal structure. We call such solids hydrates‚ and we call the bound water the water of hydration. A hydrate has a definite number of water molecules bound to each anhydrous salt unit. The formula of the hydrate copper(II) sulfate pentahydrate is CuSO4 · 5 H2O The dot indicates that the molecules of water are attached to the ions in

Determination is a positive emotion that involves persevering towards a difficult goal in spite of obstacles.[1][2] Determination occurs prior to goal attainment and serves to motivate behavior that will help achieve one’s goal. Empirical research suggests that people consider determination to be an emotion; in other words‚ determination is not just a cognitive state‚ but rather an affective state.[3] In the psychology literature‚ researchers have studied determination under other terms‚ including
