IB Chemistry 2 Prompt -Design an experiment relating to or utilizing the concepts of stoichiometry. Background Information -Stoichiometry is the study of the quantitative relationships between reactants and products. You can calculate or predict the amount of reactants needed or product will be produced from a balanced equation with some known quantitative physical properties. Stoichiometry was first introduced to chemistry by Jeremias Benjamin Richter from Germany in the late 18th century

Introduction: The importance of this lab is to get a deeper understanding of how the concepts of solutions and insolubility applies to the lab’s purpose of making chalk using precipitation reactions. A precipitation reaction is when a solid/ precipitate (insoluble) is formed when two solutions that contain soluble salts are combined. Some additional scientific concepts investigated in this lab are insolubility‚ double replacement‚ and limiting reactants. Insolubility occurs when a solute is incapable

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

n this lab experiment factors that affected solubility are temperature‚ liquids‚ concentration‚ pressure‚ polarity‚ and molecule. In this experiment we use temperature‚ centrifuge‚ and concentration solutions to be able to achieve the results that we wanted. Step one of the experiment was to mix HCl‚ to cause a precipitation form‚ after that we had to decant the solution‚ then we used a centrifuged to separate the the precipitate of the supernatant liquid. After the decant was done‚ then the process

That‚ plus the fact that all the starting and finishing materials are non hazardous and safe‚ is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited

Evolution Lab The finches on Darwin and Wallace Islands feed on seeds produced by plants growing on these islands. There are three categories of seeds: soft seeds‚ produced by plants that do well under wet conditions; seeds that are intermediate in hardness‚ produced by plants that do best under moderate precipitation; and hard seeds‚ produced by plants that dominate in drought conditions. The lab is based on a model for the evolution of quantitative traits-characteristics of an individual that
