EXPERIMENT 6 – Empirical Formula of a Compound INTRODUCTION Chemical formulas indicate the composition of compounds. A formula that gives only the simplest ratio of the relative number of atoms in a compound is the empirical formula or simplest formula. The ratio usually consists of small whole numbers. We call a formula that gives the actual numbers of each type of atom in a compound the molecular formula. The numbers in a molecular formula will be whole number multiples of the numbers in an empirical

Value density/ packaging density IBMS 203 Huang Yang 0842317 Value density is defined as the value of a good per pound of weight. For example‚ the value of a pound of diamond which is much higher than the value of a pound of bananas. That is the value density‚ two goods have same size and same weight‚ but they have different values. It is used to determine a product where should be stored and how can it shipped. It can show how important of transportation cost in the total product

Density: Using Experimental Techniques to Solve an Inquiry based problem ABSTRACT The topic of this experiment is Density. The objective is to find two ways in which the density of a given object can be determined‚ and to find out which of the two ways is more accurate and hence better to use in such a case. The two methods used in this experiment are finding the dimensions of the object and water displacement. These are two ways of finding the volume of an object‚ and they were chosen since

slavery. 5. Why did the northerners and southerners disagree about the Kansas-Nebraska act? The reason the northerners and southerners disagreed about the Kansas-Nebraska act was because they thought it was taking power away from them. 6. How did “Bleeding Kansas” cause problems for democrats? “Bleeding Kansas” caused problems for democrats because the antislavery boycotted the government. Slavery Dominates Politics 7. What positions did Lincoln and Douglass take in our debates

Practical Report Experiment 1 Abstract In this experiment we found that you can calculate the density of elements with close presotion with crude experiments Introduction The aim of this experiment was to see how close you could measure the density of atoms with crude experiments. The second part of the experiment dealt with Solubility of large ions and their Hydration enthalpy. Hydration enthalpy is the enthalpy change when 1 mole of an ionic substance dissolves in a solution to give a solution

Ashley Robins 9/13/11 Honors Chemistry Period 4 Density Lab Purpose: 1. To determine the density of a solid using different laboratory techniques for measuring volume. 2. To use the intensive property of density to identify an unknown substance. Procedure: 1. Obtain a bag marked with a number containing a cube and a cylinder from the teacher. Record the number on the bag in the data table. Density of a cube: Using a balance‚ record the mass of the cube to the nearest tenth of a gram

Period 7 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

Density (Linearized plot) TA: Blue Rex rex Group Members: Billy and Mandy Tuesday; 1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then
