Purpose: The purpose of this lab was to analyze the trends of the atomic radius (AR) and the first ionization energy (IE) for the first 36 elements of the periodic table. Procedure: A piece of graph paper was given out by the teacher. A periodic table that has the atomic number‚ atomic radius (AR)‚ and first ionization energy (IE) was given out by the teacher. A sheet of paper was taken out to record the elements‚ atomic number‚ atomic radius (AR)‚ and the first ionization energy (IE). To record

Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment

We measured its relative mass and recorded in our lab notebook. The liquid was consequently poured into the cylinder and the volume measured. To finish off the experiment‚ section three was conducted in order to compare samples of known liquids. Samples of olive oil‚ isopropyl‚ and water were obtained

Separation of a Mixture: Unknown # 12-Green Chemistry 221 with Professor Thomas Quale May 2012 Formal Lab Report Abstract An unknown sample‚ # 12-Green‚ was separated into its individual variable components‚ iron‚ ammonium chloride‚ silicon dioxide‚ and sodium chloride. The techniques used to separate the components of unknown # 12-Green‚ magnetism‚ sublimation‚ extraction‚ and filtration‚ were chosen based on the unique properties of each component. Using these separation techniques‚ each substance

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Analysis of Alum‚ AlK(SO4)2・12 H2O Partner: Cindy Date: Sep 15‚ 2011 Purpose: The purpose of this experiment is to verify the identity of the alum by finding the properties of the substance; melting point and mole ratio of the water to the anhydrous. Every substance has unique characteristics which help to determine the identity of it. The actual values of the properties can be compared to the experimental values. In real life‚ this can be used to determine the unknown medicines. Hypothesis:

The purpose of the lab was to construct a graph of sugar content versus density for 5 sugar solutions and to determine the sugar content of the 5 beverages using graphical analysis. The hypothesis was that if a beverage has more sugar‚ then it will be more dense. The results of the lab included the densities of all the solutions and beverages‚ which was then graphed. Then‚ using the graph‚ the sugar content for the beverages was determined and a rank of the beverages was created. From lowest sugar
