all-purpose flour. The ingredients for that buttery flakey crust; 1 cup butter flavored shortening, 2 ½ cups all-purpose flour, 2 tbsp. sugar, 1 tsp. salt and 1/3 cup ice water. Now it’s time to do the mixing!!
The relative reactivity of the hydrogens H1, H2, H3 , and H4 were 0.37, 1.4, 2.9, and 1.0 respectively. The radical chlorination of 1-chlorobutane follows the radical reaction mechanism. Abstraction of hydrogen from 1-chlorobutane by the chlorine radical occurs in the first part of the propagation step. Depending on which hydrogen is abstracted by the chlorine radical, determines which product is formed. Hydrogens on the alkene have different reactivity which determines which isomer is favored.
Rate of Evaporation and Intermolecular Forces Laboratory Report General Chemistry Laboratory Bernard Determining the Rate of Evaporation and Intermolecular Forces. Introduction Evaporations occur when a liquid absorbs energy and changes to gas. The evaporation process occurs only at the surface of a liquid compared to the boiling process in which liquid also changes to gas at the bottom of the liquid where the additional heat source is located. Two types of organic compounds were encountered in this experiment- alkanes and alcohols. Alkanes composed of only carbon and hydrogen atoms are referred to as hydrocarbons.
* 100% key lime * 50% key lime * 25% key lime 3. This is the formula to produce different key lime concentrations. * M1V1 = M2V2 Preparing of Kirby-Bauer test Materials and apparatus * Broth cultures of P. anvenginosa, E coli, S. aurens and B. spizizenii * Sterile cotton swab * Forceps * Bunsen burner * Whatman filter paper (small piece after punch) * Key lime discs * Parafilm Procedure 1. Swirl the contents of the broth culture of P. anvenginosa until it is equally murky throughout. 2.
Place the 5cm strip of tape on the bottom half edge of the Petri dish. Place the 100 kernels in the bottom half of the Petri dish. Notice that the 100 popcorn kernels are to represent 100 nuclei of atoms. Put the lid on the Petri dish and shake it around, make sure not to shake fast or hard. Put the dish on the flat surface and count out the popcorn kernels that are pointing to the 5cm masking tape.
The Empirical Formula of an Oxide, Purpose: The purpose of this lab was to determine the empirical formula of magnesium oxide. To do this, we measured the weight of the magnesium before the reaction with oxygen, and then measure it after it had bonded with the oxygen. After the mass of the items were collected, the data was calculated in empirical formula. Background: The empirical formula of a compound is the whole number ratio of the elements in a compound. For example, the empirical formula of water is H2O meaning for every 1 O atom there are 2 H atoms.
Shape dough into 1 inch balls; place 2 inches apart on ungreased cookie sheets. Bake at 400 deg. F for 12 to 15 minutes or until edges are lightly browned. Roll in additional powdered sugar while warm. Cool
The general form of a synthetic reaction looks like this: A + B AB. Here are 5 examples of synthetic reactions: 1) 2H2 + O2 2H2O (The burning of hydrogen to form water) 2) 2C + O2 C O2 (The burning of carbon to form carbon dioxide) 3) 2CO + O2 2CO2 (The burning of carbon monoxide to form carbon dioxide) 4) CaO + H2O Ca(OH)2 (The reaction of calcium oxide
This is cream that when whipped, holds stiff peaks. The frosting recipe is adapted from 'The Waldorf-Astoria Cookbook' by John Doherty. If you are just spreading the frosting on the tops of the cupcakes with an offset spatula or knife I would half the Cream Cheese Frosting recipe. But if you want to pipe lovely tall swirls (I used a Wilton 1M star tip) of
(b) Calculate the volume of 0.2M UO3- needed to react with 20.00 cm3 of 0.1M Cr2O72-. 3. 24.40 g of hydrated iron(II) sulphate, FeSO4.xH2O was dissolved and made up to 1.0 dm3 of aqueous solution, acidified with sulphuric acid. 25.00 cm3 of the solution was titrated with 20.00 cm3 of 0.022M potassium manganate(VII) solution for complete oxidation. a) Write the equation for the reaction.
