If only they knew what was in the mystery mixture. After a long time of experimenting‚ the 8th grade scientist came to a decision on how they are going to figure what is in the mystery mixture. Once they started‚ they all looked at its physical properties. Then the scientists thought about the chemical reactions‚ and how that will help the claim the scientists had. More than half of the scientists thought it was baking soda and citric acid. When combining baking soda and citric acid together‚ the

He wants them dead because in the beginning the witches predicted that banquos son fleance would be king. Banquo sorta gave away that he knows that Macbeth killed Duncan. Macbeth hires two murderers to kill fleance and Banquo. They are told to wait within castle walls for Macbeth’s signal. Banquo is killed but fleance escapes. It means that the news of fleances escape would have secured his throne. Banquos ghost is sitting in Macbeth’s chair at the head of the banquet table.Three distinctive characteristics

Analysis of an Unknown Mixture Performed: 2/13/14 Submitted: 3/3/14 Abstract: The purpose of this experiment was to separate and identify the two unknown compounds. The sample used was 105 and it contain 2-propanol and 2-heptanone. IR spectrums were taken of the contents of the second and sixth test tubes and showed the presence of an OH functional group and a small amount of ketone in test tube two and a large presence of ketone in test tube six. The average boiling points of the test tubes

more elements that can be changed. Water is a compound. It contains both Hydrogen and oxygen that can stand alone by itself. The mixture is when two different substances that are blended together. The air is a mixture of these elements carbon dioxide‚ nitrogen‚ and other stuff. Most mixtures are known to be naturally. The main difference between the compound and the mixture is how they are combined. In the pure substance‚ the only way to know if it is an element or compound‚ is by studying the actually

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

Types of Mixtures Lab Purpose • To classify types of mixtures • To determine the polarity of substances Background Information: Polarity In the middle of the night of March 24‚ 1989‚ the giant oil tanker Exxon Valdez veered out of the shipping lanes in Alaska’s Prince William Sound and struck a reef. The side of the tanker was ripped open‚ and 11 million gallons of crude oil flowed out into Alaska’s clear blue waters. Because petroleum oil is insoluble (does not dissolve) in water and less

Introduction A heterogeneous mixture is not uniform throughout. Therefore‚ separate components of a heterogeneous mixture can be separated by using differences in the components’ physical properties. In this laboratory experiment‚ I attempted to experimentally verify that the components of a heterogeneous mixture containing salt‚ sand‚ and benzoic acid can be separated using the separate components’ solubility properties (ability to dissolve in water). Because it is known that organic compounds

Chemical Separation Introduction: The objective of this experiment was to extract the pigments from spinach leaves‚ perform Thin Layer Chromatography (TLC) on the spinach leaf extract‚ and then determine the best solvent mixture to use to separate the pigments in the extract. The pigments are located inside the chloroplast walls in the cells of the spinach leaves. In order to obtain the pigments the cell walls must be broken down thus exposing the pigment containing chloroplasts. Upon
