Melissa Carrithers AP Chemistry 12/17/14 Rate Law Determination Pre-Lab Purpose: The purpose of this lab is to observe the reaction between sodium hydroxide and crystal violet so that the order of the reaction could be determined along with the rate constant‚ k‚ and the half-life for this reaction. Hypothesis: If the reaction between crystal violet and sodium hydroxide reacts appropriately‚ then the order will be first order. Procedure: Mix 10 mL of sodium hydroxide and crystal violet solution

Lacsap’s Fractions IB Math SL Internal Assessment Paper 1 Lacsap’s Fractions Lacsap is Pascal spelled backward. Therefore‚ Pascal’s Triangle can be used practically especially with this diagram. (Diagram 1) This diagram is of Pascal’s Triangle and shows the relationship of the row number‚ n‚ and the diagonal columns‚ r. This is evident in Lacsap’s Fractions as well‚ and can be used to help understand some of the following questions. Solutions Describe how to find

Lab 3: Reaction Order and Rate Laws Name: Student Lab Partners: None Date of Experiment: 16 March 2014 Location: My House Course Number: CHE112 Abstract: When combining compounds‚ there are always two roles considered in the reaction. These are reactants and products. Reactants are the initial compounds before mixing. The products are synonymous with the term byproduct‚ or what remains when the reaction occurs. For example‚ Sodium (Na+) and Chlorine (Cl-)

Ionic Reactions Introduction: Today we are going to observe the chemical changes when mixing two solutions. Some will change colors‚ produce gases proving if the solutions are soluble or insoluble. Materials and Methods: I first pulled out the small wells and place two drops of the Cobalt (II) Nitrate in seven of the wells. I then moved to the next row and placed two drops of Copper (II) Nitrate in the next row‚ into seven of the wells‚ and so on with the other three Nitrates. I then cut off

Premium Null hypothesis Statistical hypothesis testing Hypothesis
water molecules can incorporate themselves into the ionic crystal structure. Water‚ after all‚ has an oxygen atom with two lone pairs capable of behaving as a Lewis base; it bonds easily to metal ions as evidenced by complex ions in transition metal chemistry. The metal ions and the water molecules are bonded by dative coordinate bonds from the oxygen atom of the water. Therefore‚ Water of crystallization is water that is stoichiometrically bound into a crystal. Crystal salts containing water of crystallization

Factors Affecting Reactions I. Factors Affecting Reactions [545] • Every chemical proceeds at its own rate. • By changing the conditions of the reaction‚ the rate of almost any reaction can be modified. • The rate of a chemical reaction depends upon: o Temperature o Concentration o Particle Size[SA] o Catalyst A. Temperature [545] • Increasing the temperature causes molecules to move faster‚ so there’s an increased chance of them colliding
