Styles Inventory (LSI) is a survey that “measures 12 specific styles of patterns of thinking that can either help or hinder a person from reaching his or her potential” (Human Synergistics). Human behavior is a perplex issue and is most often influenced by culture‚ religion‚ education‚ value systems‚ ethnic and other factors. Individuals often know what drives there particular styles but unless studied they may not know what their strengths and weaknesses actually are. The LSI survey identifies

Question 1 (Limiting Reagent) 15.00 g aluminum sulfide & 10.00 g water react until the limiting reagent is used up. [Atomic mass: H = 1.008‚ Al = 26.98‚ S = 32.07‚ O = 16.00] Here is the balanced equation for the reaction: Al2S3 + 6 H2O ( 2 Al (OH)3 + 3 H2S (i) Which of the two reactants is the limiting reagent? (ii) What is the maximum mass of H2S which can be formed from these reagents? (iii) How much excess reagent remains after the reaction is complete

Observing a Limiting Reactant An experiment was carried out to predict the limiting reactant in a chemical reaction between Magnesium and Hydrochloric acid‚ using the mole concept. Limiting Reactant: It is the reactant that will deplete or will be used up first during a chemical reaction. Limiting reactant also determine how long the reaction will last for. Balanced Equation: Mg + 2HCl = MgCl2 + H2 The balanced equation is needed to determine the mole ratio between the two reactants. From

By examining one specific example of stoichiometric determination‚ which is: “Stoichiometry and limiting reacting”‚ we found out the different mass proportions in which substance react. In this case‚ we used two common acids for this experiment (HCl‚ and H2SO4) and base NaOH Introduction: For this experiment‚ we use Stoichiometry and limiting reactant. The limiting reactant refers to the reactant that controls the amount of product that is

LSI Assignment My Results [pic] Personal Thinking Styles Based on the information presented in the survey‚ it is clear to see that my personal thinking style is highest for my affiliative style and approach. This is primarily because I like to ensure that I have support whenever I make my way in a test whether it is on an academic level or on a personal basis. My ability to forge these relationships with my cohorts is something that I value very much as I’m a strong believer that you learn

During this lab‚ we found the excess reactant and limiting reactant between Aluminum and Copper (ll) Chloride. Using stoichiometry‚ we were able to make predictions. Through the reaction 2Al + 2CuCl₂ → 3Cu + 2AlCl₃ we carried out this experiment and determined that the limiting reactant was CuCl₂ and that the aluminum was in excess. We also determined the percentage yield of copper. Purpose: The purpose of this experiment was to determine the limiting reactant and percentage yield of the reaction that

Limiting Science Rough Draft #2 David Baltimore’s written work of Limiting Science: A Biologist’s Perspective discusses the controversy of research in molecular biology and its limitless freedom‚ disputing there should be freedom in which direction science heads‚ but the public should decide the pace at which it goes. Baltimore first begins his argument with the discussion of how molecular biology began. It was born from individual sciences where attempts at trying to solve the mysteries in these

from theoretical yield. Through simple molar calculations‚ using the coefficients in the balanced chemical equation( CaCl2(aq) + 2NaOH(aq) Ca(OH)2 + CaCl2)‚ the limiting reagent could be determined from the volumes of reactants used. The number two to four tests turned out as expected‚ NaOH and CaCl2 respectively being the limiting reagents. In the second test‚ according to our calculations‚ the products should have completely reacted‚ leaving pure water after filtration. In the test‚ the addition
