Title: Separation of Mixture of Solids - Experiment 3 Date: 9/21/13 Purpose: This experiment is designed to show the different ways to separate solid mixtures into individual elements. It will also determine whether a substance can be considered “pure” or not‚ as well as determining the solubility of each mixture in water. Procedure: 1) Weigh the amount of the mixture on the digital scale. Separate the Iron out by using a magnet to filter out the Iron element. 2) Take the remaining mixture

Abstract Qualitative analysis‚ a branch of analytical chemistry‚ deals with the identity of a substance found in a given sample‚ and not the amount of substance in it. It only concerns the substances present or absent in a given sample. Qualitative analysis is therefore used to determine unknown ions present in chemical samples by observing and analyzing results from various reactions of the sample with chemicals. Qualitative analysis is done through a series of steps. It is usually divided

Corporate Finance Home Wok Chapter 4 Q1: Simple Interest versus compound Interest First City Bank pays 9 percent simple interest on its savings account balances‚ whereas Second City Bank pays 9 percent interest compounded annually. If you made a $5‚000 deposit in each bank‚ how much more money would you earn from your Second City Bank account at the end of 10 years? A: First City Bank: 5000*(1+10*0.09)=9500 Second City Bank: 5000*(1+0.09)10=11837 11837-9500=2337 So we will earn more $2‚337 from
