Purpose/ objectives: 1. To learn if food concentrations affect yeast activity 2. To improve skills in writing a lab report better 3. To practice measuring skills 4. To understand how yeast works Materials: * * 6 identical large test tubes (18 X 150mm) * 1 graduated cylinder (24ml) * Molasses stock solution ( 1:4- molasses: water) Dropper * Yeast suspension (1 gram of dry yeast in 100 mls water) * Aluminum foil * 1 test tube rack * 1 graduated cylinder (small) * 1 beaker * 6 small test tube (10 X 75mm) * Rule marked in millimeters Hypothesis: If you add more molasses to the yeast then the gas would became greater because the yeast cells reproduce so the waste became greater and
For my speech, I am going to explain to you, how to make German Chocolate Cake. First, you need all your ingredients. You need a box of German chocolate cake mix, 1 1/4 cups of water and 1/3 cup of oil. It’s a bit fattening, but sometimes fat makes it better and it will hold the mixture together better. You need 3 eggs, a bag of pecans, a bag of coconut, 1/2 stick of butter, a greased 9 by 13 inch pan, a measuring cup, a mixing bowl, and a whisk or an electric mixer.
It is for children with wheat allergies. The dough is quite sticky at first, but just continues kneading it and it will turn out beautifully. • ½ cup rice flour • ½ cup cornstarch • ½ cup salt • 2 tsp cream of tartar • 1 cup cold water • 1 tsp cooking oil • Food coloring Combine all ingredients except food coloring in a medium saucepan. Cook over medium heat stirring constantly until mixture thickens and forms a ball. Allow the dough to cool and then add in your food coloring.
It was important for the company to select the correct variables when determining segments and also gain insight on why home usage of baking soda is declining (e.g. lifestyles, behaviors) to effectively reposition the product. They then identified customer segments that are distinct and identifiable (e.g. how much is purchased?) that can be targeted through innovative marketing.
Purpose: The purpose of this experiment is to determine the quantities of the impurities of the baking soda produced by the Athenium Baking Soda Company and also identify the salts present in the baking soda sample. Introduction: NaHCO3, sodium bicarbonate or even sodium hydrogen carbonate, are many different names for a common item, baking soda. Baking soda are has many different uses, most of them involving cleaning household items. It does have other uses such as a hygiene product. There are several different ways to create baking soda, but the Athenium Baking Soda Company chose to make baking soda by reacting ammonium hydrogen carbonate with a highly concentrated aqueous solution of NaCl or brine.
Because baking soda is a natural compound, using it in these products can replace potentially environmentally harmful products. Out of several methods to produce baking soda, the Athenium Baking Soda Company has chosen the method of reacting brine with ammonium hydrogen carbonate to form baking soda: NH4HCO3(s) + NaCl(aq) => NaHCO3(aq) + NH4Cl(aq) Brine is defined as water containing a higher concentration of sodium chloride than typical seawater, along with the possible impurities potassium chloride (KCl), lithium chloride (LiCl), and calcium chloride (CaCl2) (brinechem). After NaHCO3 is dried and filtered, it may contain contaminants (KCl, LiCl, CaCl2) in the residue. To ensure the standards of the products are kept high, many baking soda manufacturing companies employ technicians and scientists to analyze and approve the products. This analysis is commonly referred to as quality control and includes periodic inspections designed to ensure the company’s products are meeting the set standards such as being uncontaminated, not losing quality during the manufacturing process, and not containing chemical structure or composition imperfections.
Background Information: Baking soda (NaHCO3) constitutes a compound that has numerous practical and economical uses. NaHCO3 is used in fire extinguishers, household cleaners, fruit cleaner, heavy duty dish cleanser, hand and face wash, tooth and denture cleaner, for cooking and for acid indigestion. The wondrous applicability of baking soda is that it can be created by using a number of methods. The Athenium Baking Soda Company has decided to make baking soda using the method of reacting crystalline ammonium hydrogen carbonate with brine, which is “salt water with a high concentration of sodium chloride, as well as potassium chloride, lithium chloride, and calcium chloride.” NH4HCO3(s) + NaCl(aq) NaHCO3(aq) + NH4Cl(aq) Ammonium hydrogen carbonate + Brine Baking soda + Ammonium chloride When the baking soda is dried and filtered, there may be contaminants present in the residue, such as KCl, LiCl, and CaCl2. To analyze the purity composition in their baking soda, as well as the quality of workmanship, structural flaws, composition, and longevity, the Athenium Baking Soda Company has hired our team.
Add the softened cream cheese to the food processor and make sure that the oreo cookies and cream cheese are mixed well together. One will then line a cookie sheet with wax paper and roll the dough into small bite sized balls. To make this easy, take the one-fourth measuring scoop and scoop the dough out of the bowl and onto the cookie sheet. Once the bite sized balls are lined up on the cookie sheet, place them in the freezer for thirty minutes. While the balls are freezing, one should take this time to melt the white chocolate.
Then you get a large spoon and mix it all together until it forms into dough. 3. Extra flour is added to the dough, table and roller so they do not sick. 4. Roll the dough out until it is a quart of an inch thick and then use your preferred cutter to shape the dough into cookies.
To make peach cobbler you will need a few basic items: first clean and sanitize your work area (kitchen counter). Then you will need your mixing tools and equipment which is bowls, spoons, pan, oven mitten and measuring cups. Then your dry ingredients which are flour, sugar, cinnamon, and your wet ingredients are lemon juice, butter, and peaches. As the cook you decide what to put in the peach cobbler since this process can be messy. So you should wear an apron don’t make this anywhere else accept on a clean counter.
