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

SEPERATION OF A MIXTURE Purpose: The purpose of this lab is to find out how components of a mixture can be separated and analyzed. Procedure: The procedure for this lab report is as follows: 1. Mixture is taken‚ and has to be measured in order to meet the requirements of 2-3g. 2. The mass of the tray is measured and then the scale is zeroed out and the mixture is added to find out the mass of the original mixture. 3. Next‚ find the mass of the 250mL beaker‚ zero out the scale

Purpose: The purpose of this separations lab was to see what the most efficient way is to separate a dry mixture using all kinds of materials. The mixture was of salt‚ sand‚ iron filings‚ and bird seed. Results: The results of mass recovered were very different from what the actual mass was. The iron filings were about the same besides recovering 0.1 extra gram. For the bird seed‚ there was 0.7 grams more collected from the original mass that is 2.0 grams. The sand had 2.5 grams recovered‚ where

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

in Ms. O’Brien’s Honors Science class we conducted two experiments the Mixed Substances Lab and the Investigating Mixtures Lab. The objective of the Investigating Mixtures Lab was “To observe that not all liquids behave the same way when mixed with other liquids”. Before we started the lab we we each created a hypothesis mine was “If the water and vegetable oil are mixed and the two combine and make a mixture‚ then the vegetable oil will float and the water will sink”. This is the important information

-Unknown Mixtures Lab- Purpose: The aim of this experiment was to find out the two substances of the unknown mixture from salt‚ sugar‚ dirt‚ and baking soda by looking at its properties. Hypothesis: Find the unknown substance by testing it out by heating it‚ pouring water‚ vinegar‚ and observing it . Procedure: 1) Materials- * 100ml of water * Vinegar * Bunsen Burner * 2 beakers * 1 spatula 2) First‚ do steps (3-6)to find out the properties of salt‚ sugar

Name Date Lab: Denisty – Solids and Liquids Part 1: Density Background Information: The density of an object is how much “stuff”‚ or molecules‚ a substance is made of. Density is how tightly packed the molecules are. To calculate the density of a substance we need to know the mass (weight) of the substance and the volume (how much space) of the substance. Mass is determined by weighing an object. Volume of regular shaped objects is calculated by measuring
