It’s not hard to make kabsa if you follow these steps. You should have all the ingredients ready. This is important because you don’t want to be surprised when you can’t find what you need. Then you can begin the process of making kabsa. First‚ you need to cut up the green pepper‚ onion‚ garlic‚ and two tomatoes. You can also cut up the chicken or the meat at this time. Then you can put the garlic‚ green pepper‚ and onion in oil and cook them until they are brown. Keep the stove on a medium

Ben Quinones AP Chem Mr. Perry 25 January 2013 Molar Mass by Freezing Point Depression Conclusion: My Lab unsuccessfully found the molar mass of the unknown given to us in the lab. We were tasked with finding the molar mass of an unknown compound using the colligative property of Freezing Point Depression. The way we did this was first finding the temperature at which ice crystals form for just regular BHT. Luckily thanks to our TA we were given temperature probes so we could pinpoint exact

Title: Boiling Red Water Materials: Water A clear glass or plastic cup Food Colouring (Optional) 1/4 cup Vegetable Oil 1 tsp Salt Procedures: Fill a glass 3/4 full with water Add 5 drops of food colouring Add the oil Add salt How it works: The salt brings the oil down with it as it sinks to the bottom of the bottle. When it reaches the water‚ the salt dissolves and the oil is then free to float back to the top. NOTE: this is not originally

Purpose: a) Determine the melting points of two organic compounds known to have the same melting range when pure. b) Determine the mixture melting point of a mixture of the two pure compounds. c) Identify an unknown organic compound by determining its melting point and mixture melting point. Procedure and Observations: Using the procedure outlined in Appendix A of the Lab Manual‚ approximately equal samples of p-Nitrophenol and acetanilide‚ which are known to have the same melting range

Investigation of the point of incipient plasmolysis of onion cells (Allium cepa) using NaCl (Sodium Chloride) concentrations of 0.1M‚ 0.2M‚ 0.3M‚ 0.4M‚ 0.5M‚ 0.6M Design Research Question (Aim): The aim of this lab was to determine the point of incipient plasmolysis of onion (Allium cepa) cells using Sodium Chloride (NaCl) concentrations of 0.1M‚ 0.2M‚ 0.3M‚ 0.4M‚ 0.5M‚ 0.6M. Hypothesis: When the water concentration of a solution outside the cell is lower than the concentration inside the cell

The objective of this lab was to identify an unknown compound by determining the melting point range using fast and slow ramps. Also‚ to determine the eutectic point of Urea and Cinnamic Acid. An unknown compound that was numbered 8 was chosen. A small amount of the unknown compound was placed in a weighing paper using a spatula. The weighing paper was folded in half twice and then was grinded using a spatula. After the unknown compound was grinded about 1-2mm was added into a capillary tube. A

Results My unknown sample was number 18. I did three melting point trials‚ which resulted in a melting point range of approximately 120°C to 122°C‚ as shown in Table 1. I also did two mixed melting point trials using Benzoic Acid and Succinimide‚ as shown in Table 2. Percent recovery is 28.26 grams. Table 1: Unknown Melting Point Trials Trial Melting Point 1 120°C – 122°C 2 120°C – 122°C 3 119°C - 122°C Table 2: Mixed Melting Point Trials Trial Benzoic Acid MP Unknown #18 MP Succinimide MP

saLT AFFECT THE BOILING POINT OF WATER? 1 How Does Salt Affect the Boiling Point of Water? Elizabeth Mompoint Everglades High School HOW does saLT AFFECT THE BOILING POINT OF WATER? 2 Abstract The purpose of this experiment was to determine whether or not salt would affect the boiling point of water. Much of the research I conducted rejected my hypothesis which stated: if I add salt to water‚ then the boiling point of the water

from the bed‚ she tiptoed through the boxes which lay everywhere and put a kettle of water onto boil. Waiting‚ she glanced over all her possessions‚ grateful she had the whole day before her. She scooped instant coffee into the cup and poured in now boiling water. Stirring the coffee‚ she tried to decide where to begin. She took a quick sip of coffee and searched her box of books. She ordered them neatly on a shelf. Then‚ she lifted her suitcase onto her bed. She unlatched the clasps and opened it and

Raghed Odeh Chem 227 11/01/2017 Using Conductivity to Find an Equivalence Point Provide a brief statement of the purpose of this activity. Be sure to define equivalence point. Explain conductivity and the idea behind why conductivity can be used in determining the equivalence point in a titration. The purpose of this experiment was to use the conductivity to find the equivalence point. The equivalence point is the point in a titration where the amount of titrant added is enough to completely neutralize
