nitrateAmmonium Nitrate How they are manufactured? Ammonium nitrate is made commercially by passing ammonia gas (NH3) and a water solution of nitric acid (HNO3) through a pipe. The ammonia combines with the nitric acid to form ammonium nitrate. The formula for this reaction can be written as NH3 + HNO3 → NH4NO3. Large amounts of heat are released during the reaction‚ so the pipe and supporting equipment must be very strong. The solution of ammonium nitrate in water is allowed to evaporate‚ leaving

Title: Separation of a Mixture of Solids Purpose: Learn and demonstrate how to separate different ingredients from a mixture of solids using different methods based on the properties of each ingredient. Procedure: I weighed mixture and tools‚ and proceeded to begin separating each ingredient. I used a magnet to separate the iron from the mixture. Then I heated the mixture in water to get the non-soluble sand out. Then I filtered out the benzoic acid after cooling it into a crystal form

The Separation of a Liquid Mixture by Simple Distillation Objective The purpose of doing this experiment is to separate two miscible liquids samples of cyclohexane and toluene using simple distillation. The objectives will be to record boiling range and volumes (mL) of distillates that are attained during the process of distillation. Background Distillation is a frequently used technique for separating mixtures based on differences in the boiling points of components in the mixture. The

SCIENCE REPORT AMMONIUM NITRATE NH4NO3 Problem Our task was to investigate what the optimum ratio of solute to solvent that will produce the maximum cooling/heating effect? Hypothesis With a smaller quantity of water (50mls) and the same amount of Ammonium Nitrate added. After any period of time the mixture will be a cooler temperature than that of a mixture with a larger quantity of water. Variables X Water X Teaspoons X Time X Ammonium Nitrate X Thermometer X Stirring

conduct and taught based upon the primary instruction and introduction to mixtures. With this lab I was able to determine and execute the proper separation of a mixture of solids through various means‚ such as evaporation and filtration. Using these techniques presented the separation of different ingredients from a mixture was conducted based upon the usage of individual physical properties of each substance presented in the mixture. . Observations: Throughout this experiment I noted several things

Nupoor Matieda October 10‚ 2014 PD 9/10 Lab Report Separation of a Mixture of Sand and Salt Goal(s): To separate a mixture of sand and salt and to find the percent of each component by mass of each mixture Background Theory: A mixture is a combination of two or more pure substances in which each pure substance retains its individual chemical properties. Mixtures can be separated by physical processes such as filtration and evaporation. Filtration is a process where solids

Separation of a Mixture Do-Your-Own-Lab What you will need to do: 1. Create a flow chart for the separation of your unknown mixture – BERFORE doing lab 2. Create data table – BEFORE doing lab 3. Do lab 4. Analyze data – calculate percent composition of your unknown mixture = 15 points = 30% 5. Write a complete lab report = 35 points = 70% 1. A flow chart is often used to illustrate the steps involved in the separation of a mixture. Flow charts are constructed BEFORE

Student’s experiments can be done in groups. Groups can be given different mixtures. Each group then carry out their own experiment‚ makes a write up of their procedure and presents to the rest of the class together with the samples obtained. UNIT 1: MIXTURES AND PURE SUBSTANCES This unit is suitable for senior one (S1) BRIEF DESCRIPTION OF THE UNIT: This unit deals with: • Methods of separating mixtures. • Methods of drying solids. • Methods of determining purity of solids
