    Basic Stoichiometry PhET Lab rvsd 2/2011 Let’s make some sandviches! _ Introduction: When we bake/cook something‚ we use a specific amount of each ingredient. Imagine if you made a batch of cookies and used way too many eggs‚ or not enough sugar. YUCK! In chemistry‚ reactions proceed with very specific recipes. The study of these recipes is stoichiometry. When the reactants are present in the correct amounts‚ the reaction will produce products. What happens if there are more or less of

    Name:______________________________Period:______ The Ramp (and Friction) PhET Simulation Lab go to: phet.colorado.edu/en/simulation/ramp-forces-and-motion Introduction: When an object is dragged across a surface‚ the force of friction that must be overcome depends on the normal force as F=uN and the normal force is given by N= Wy‚ the vertical component of weight pointing perpendicular to the surface. When the angle of an inclined plane changes‚ the normal force changes and so does the friction. In this lab‚ you will change the angle of an

    Stoichiometry I. Introduction/ Purpose: Stoichiometry is the study of the quantitative‚ or measurable‚ relationships that exist in chemical formulas and also chemical reactions. The calculations of a stoichiometry problem depend upon balanced chemical equations. The coefficients of the balanced equations indicate the molar ratio of the reactants and products taking part in the reaction. There are three major categories of stoichiometry problems such as mass-mass‚ mass-volume‚ and volume-volume

    Molecule Polarity PhET Lab A study of electronegativity‚ bond polarity‚ and molecular polarity Introduction: In this atomic-level simulation‚ you will investigate how atoms’ electronegativity value affects the bonds they produce. When two atoms bond‚ a pair of electrons is shared between atoms. Electronegativity is a measure of a single atom’s ability to hoard electrons shared in that bond. In this lab you will work diligently‚ at your own pace‚ to answer a number of questions. To begin‚ from

    Stoichiometry Lab Stoichiometry is the end result of adding up chemical elements that were involved in chemical reactions (http://dictionary.reference.com/browse/stoichiometry). The word stoichiometry was obtained from two greek words meaning element and measure. This explains the definition for the term. A chemist named Jeremias Benjamin Richter was the chemist responsible for first realizing what stoichiometry was (http://www.chemteam.info/Stoichiometry/What-is-Stoichiometry.html). In 1972

    In the Stoichiometry Challenge Lab we compared the theoretical results of the reaction between sodium carbonate (Na2CO3) and sulfuric acid (H2SO4) with the actual data we found. I hypothesised that If the mole ratio between Na2SO4 and H2SO4 is 1:1 then when I react 0.5 grams of Na2SO4 (reactant with H2SO4) I should get 0.669 grams of Na2SO4. The actual reaction between .05 grams of Na2CO3 and 5 mL of of H2SO4 produced 0.79g of Na2SO4. When I were testing the reaction‚ I measured out the reactants
