The Event: The mixer beats the egg yolks in a spiral motion‚ as the sugar is being added to the eggs. Due to the fat content of the egg yolks‚ the yolks are isolated from the egg whites to avoid the deflation in the rising of the whites. Two separate batters consisting of the egg whites which were whisked until it became frothy and the egg yolks were then mixed together with butter using a spatula in folding motion. After which a sifter was used to add the flour and the cocoa powder into the mixture

Introduction: The importance of this lab is to get a deeper understanding of how the concepts of solutions and insolubility applies to the lab’s purpose of making chalk using precipitation reactions. A precipitation reaction is when a solid/ precipitate (insoluble) is formed when two solutions that contain soluble salts are combined. Some additional scientific concepts investigated in this lab are insolubility‚ double replacement‚ and limiting reactants. Insolubility occurs when a solute is incapable

The method used the density of extrcellular fluid (ECF) as a measure of ionic and osmotic concentration. All body fluids are more dense than water since they consist of water (SG=1) plus solutes. Increased solute concentration causes an

Chemical Reactions Lab Synthesis Reactions: Synthesis reactions occur when two elements or compounds combine to create one single compound. The general equation of synthesis reactions is: A+B→AB. The following are the complete balanced equations for the five synthesis reactions performed in the lab. Reaction 1: Reaction 2: Reaction 3: Reaction 4: Reaction 5: The reaction of CO2 and water is a prime example of a synthesis reaction. This is a synthesis reaction because it follows the general

Lab #1 ‐ Introduction to the Microscopy & Observation of Prokaryotic and Eukaryotic Cells Introduction Many of the cells and organisms that you will be studying are at the lower limits of visibility of light microscopes; therefore‚ it is extremely important that you attain critical lighting and focussing. It is also important to handle the microscope competently to avoid damaging either the microscope or the preparation you are studying

School Paper recycling using Organic Dye Project by: Sumber Myadagmaa Tsatsral Byambadorj 1. INTRODUCTION OF THE PROJECT Deforestation is one of the biggest problems that the world is facing. Thousands and thousands trees are cut down to make the paper that we use every day. Major labor is working as well to make the papers that we use every day. The question is what do we do with our waste papers? Most of us simply throw away the paper. Most of the countries have big paper plants.

In this lab‚ each person in the group will have two pennies. Galvanization of a penny will create a brass penny. Galvanizing the penny in sodium hydroxide with zinc causes the penny to turn from bronze to silver. Once the penny is fully galvanized you will burn the penny and spray it off and then it will turn gold. There will be a weight change also a mass change. Observing the penny to see it turn from bronze to silver to gold. Literature review Covalent bonding is a bond when atoms share pairs
