The world’s creamiest oatmeal

Image
Oatmeal can be a quick and easy breakfast, but are you making it right. In this blog post I am going to be showing you how to make oat meal the right way. Serves 1-2 people   Prep time: 10 minutes   Cook time: 20 minutes Ingredients 1/2 cup Oats 1 cup water 2 table spoon sugar 3 table spoon condense milk (can use honey) 1 teaspoon vanilla Direction Measure out the oats in a small dish and wet the oats with water for five minutes. Take a pot, add water, then leave it to boil on the stove. Then add the wet oats. Continuously stir for one minute. If the oat get too thick you can add more cold water. Add the sugar, condense milk, vanilla and stir. You can eat it with banana or grapes 1. Add oats and cold water together. ​ ​ S M L  2. Allow the water to boil. A the wet oats.    Ready to serve!! Hope to enjoy. ​ ​ S M L

Simple lemonade reciepe

  Ingredients 1/2 cup of sugar 3 cups of water 1 lemon 9 ice cubes Directions 1. Pour half of the sugar in a jar with the lemon juice. 2. Mix the sugar and the lemon juice with a spoon 3. Add the other half of the sugar and the 1/2 cup of  warm water and mix  until most of the sugar dissolve. 4. Add the remaining ingredients. Enjoy!!

Preparation of Dibromosuccinic Acid- Post Lab 9

Observations 1.       Within 5 minutes the color of the solution starts to become colorless. 2.       We added around .5ml of the bromine stock solution to the solution while it was on the water bath. 3.       The product of this experiment was in the vacuum filter for 20 minutes. Data Fumaric acid: 0.19 Bromine: 2.7 ml Final weight of Fumaric acid: .59g Theoretical yield: 0.0028 mol x 275.88 g/mol = 0.77g Percentage yield: .59g/0.77g x 100%= 76% Melting point 250-255 ◦C Question Which stereoisomer of dibromosuccinic acid (racemic melting point = 170 o C, meso melting point = 290 o C) did you obtain? The stereoisomer of dibromosuccinic is Meso. The melting point of our experiment product is between 250-255 ◦C. It is not exact meso melting point however, it is closer to meso than racemic melting point.

Isolation of Eugenol- Post Lab 8

Observation 1.       The water and spice boils very rapidly with white foam on top. 2.       It take about half an hour for the first drop of distillate. 3.       After the first drop of distillate it take around 10 minutes for the distillate to reach to 15 mL. Data Spice:  3.04 grams Test tube: 19.84 grams Test tube + spice final weight: 20.49 grams % recovery+ .64/3.04 x 100%= 21.3% Infrared Spectrum: 1.445 Question Why is steam distillation used in this experiment? Eugenol has a boiling point of 254 o C, which is very high. Stem distillation lower the boiling point of Eugenol so it can be distilled. This happen because when the solution boils the water vapor carry vaporized compound to the condensation flask. When it is in the condensation flask the liquid phase separate so it can be collected in the receiving flask.

Simple and Fractional Distillation- Post Lab 7

Observation 1.        Fractional distillation took a longer time for the compound to start drop in the receiving flask than the simple distillation. 2.        After 6ml of distillate were collected during simple distillation it takes around 5 minutes for the next 1 mL distillate. 3.        After 4 ml of distillate were collected during fractional distillation it takes around 7 to 10 for the next few ml to distillate. Data Temperature        Volume (ml) 58     1 56   2 50 3 47 4 94 5 100 6 94 7 Temperature        Volume (ml) 1 60 2 65 3 73 4 78 5 85 6 96 7 98 Question The two unknown are Heptane and hexane. Simple distillation graph has a smoother curve which makes i...

TLC and Column Chromatography- Post Lab 5

Observations: 1.       Fluorene traveled further on the TLC plate then the fluorenone. 2.       The samples on the TLC plate were not visible with eyes . 3.       After 70% hexane – 30% acetone was added, the yellow band went down faster. Data: Test tube 3 had the fluorenone, test tube 2 had fluorene and the dot label “M” is a mixture of fluorenone and fluorene. Fluorene travel up more on the TLC plate than fluorenone. Post-lab Question:   Why does fluorenone travel more slowly than fluorene? Why does acetone speed up the rate at which fluorenone travels? Fluorenone has a carbonyl group which means that it is more polar than fluorene. Since fluorenone is more polar it travel more slowly than fluorene. Acetone will speed up the rate at which both fluorene andfluorenone travels up the TLC plate. It will not change the position.
