Nuts and Bolts Purpose: The purpose of the lab is to correctly describe and distinguish samples and models of elements‚ compounds‚ and mixtures. The lab asks you to examine conceptual models of matter in which atoms of one element are represented by nuts while atoms of another element are represented by bolts. After examining each model‚ complete the following tasks: a. sketch a representative molecular picture of the model; b. describe the composition of the model in words (does

Metals & Non-Metals Metals: Good conductors of heat and electricity. Have shining luster. Malleable (this means that they can be hammered or distorted). Ductile (this means that they can be drawn into wires). Most have high melting and boiling points. Are sonorous (give out sound when beaten). Usually solid at room temperature. An exception to this is mercury‚ which is liquid in nature. Examples: Aluminum‚ Gold‚ Copper‚ Silver‚ Sodium‚ Potassium‚ Mercury. Corrode or oxidize in

Introduction If you’ve watched the previous two Olympics you’ve been fortunate enough to have seen the fastest man on the planet run the 100m and 200m. Today I want to inform you about how Usain Bolt revolutionized sprinting by being the 1st of his sport to truly be a genetic freak of nature. You have to be gifted to be an Olympic sprinter‚ but today I’m going to explain how his height and stride‚ how he gets out of the box‚ and how his closing speed makes him the fastest man on the planet.

states that an object will float in water providing its mass is equal to or less than the volume of water it displaces. The second objective of the experiment was to produce a value for water density. It was expected that when additional mass was added to a floating vessel‚ it would displace more fluid and the increasing submerged volume of water could be measured‚ and a value for water density could be calculated using the equation . The density of pure water was assumed to measure 1000 kg/m³ at
