In this lab‚ theoretical chemical equations of ionic compounds were balanced by the group to determine ratios of reactants and products. The products were determined by the group through switching the cation with their anion partner. Using this information‚ it was determined by the group‚ whether the reaction should result in a solid‚ gas‚ or water based on theoretical solubility. Then several experiments testing the reaction of these ionic compounds were performed by the partners. Two ionic compounds

Sodium hydroxide is caustic and can burn skin and clothes if it touches them. Rinse any spills well with copious amounts of water. Also‚ most of these chemicals are toxic by ingestion. So remember‚ no food or drinks in the lab! 1. All reactions will be performed in the 96-well plate. a. Place 2 drops of cobalt (II) nitrate solution into seven

Nomenclature for Ionic Compounds Ionic compounds consist of cations (positive ions) and anions (negative ions). The nomenclature‚ or naming‚ of ionic compounds is based on the names of the component ions. Here are the principal naming conventions for ionic compounds‚ along with examples to show how they are used: Roman NumeralsA Roman numeral in parentheses‚ followed by the name of the element‚ is used for elements that can form more than one positive ion. This is usually seen with metals. You

Premium Evaporation Water Laboratory equipment
The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water‚ the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions‚ write balanced equations‚ and to write net ionic equations for precipitation reactions. Based on the solubility rules my

What are Yield to Maturity (YTM) and Yield to Call (YTC)? By calculating the present and future value of bonds‚ managers can make sound decisions about their potential strengths and weaknesses as investments. Answer the following questions in this week’s Discussion 2 thread: 1. What terms (or inputs) are needed to calculate yield to maturity (YTM)? How does this compare to calculating yield to call (YTC)? To calculate the YTM you will need to use Annual Interest‚ Par value‚ Market Price

brown sugar on the amount of CO2. To do this‚ white sugar was replaced with brown sugar and the amount of CO2 produced was calculated with a vernier gas pressure sensor. The control group was yeast and white sugar and the experimental group was yeast and brown sugar. The hypothesis that if brown sugar and yeast are mixed‚ then it will produce more CO2 than a mixture of white granulated sugar and yeast was accepted. The white sugar and yeast mixture had a slope of .003254 kPa/s. The brown sugar and
