Lab Report Marisa McKinney P. 2 Purpose: To investigate the periodic variation of density in Group 4A elements. Background: When the elements are arranged in order of increasing atomic number‚ they exhibit periodic recurrence of properties. Elements in the same group in the periodic table tend to have similar physical and chemical properties. These similarities are due‚ in large part‚ to similarities among the electron configurations of the elements in a group. You can find periodic

is involved with the cannon being fired then the force of gravity would cause the cannon to start to slow down‚ wouldn’t go as far and the direction or trajectory of the cannon ball would be a curved line going down. Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &

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
