Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Hanging at a Constant Determining the effect mass has on acceleration Block 5 11/25/12 Purpose: The purpose of this lab is to determine the effect of additional mass added to a cart’s existing mass‚ without changing the applied force‚ on the acceleration of the cart. We will test this effect by hanging a constant mass to a cart and use a computer program‚ LoggerPro‚ to calculate the acceleration which is expressed through the

Chemistry Notes Oxides Oxides are used to determine whether an element is a metal or a non-metal. Most non-metals are classed as acidic oxides. While most metals are classed as basicoxides. Acidic Oxides * Reacts with water to form acids * Neutralises alkaline solution to form salt + water Basic Oxides * Neutralises acidic solutions to form salt + water Amphoeteric Oxides * These are non-metals which display both acidic and basic properties Alkaline Oxides * Reacts with

I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration

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

of blood pumped from one’s heart and clinically measured per minute. There are several points in the body where the heart rate may be taken‚ but it is read clinically at the wrist over the radial artery. Cardiac output is important because it determines one’s potentials for gas exchange and thus physical activities. Exercise over time increases one’s physical fitness. A way to measure fitness is by taking a blood pressure reading. Blood pressure is read by a device called a sphygmomanometer

the mid sixteenth century a silver mine located at Potosi‚ South America was formed. This silver mine was one of the few major silver mines in the world‚ the others located in Northern Central America and Southern Japan. This certain mine was known for its distinctive rich black flint. Extensive excavation required more than three-thousand Indians to work away with picks and hammers to break up the ore and bring it up to the surface. Just after refining the ore‚ the silver is shipped to Spain then from

Potato Osmosis and Diffusion Lab Report Emily Cocq Research Question: Will there be a difference in the experimented potato cores after being subjected to high concentrations of sugar? Introduction: Water can move through protein channels in cell membrane/cell walls. The water will move due to the water potential of the cells. If there is a greater concentration of solutes (chemicals) inside the cell than outside the cell and the chemicals can not move‚ then water will respond by moving
