Chemistry Laboratory 6A – Stoichiometric Analysis of an Iron-Copper Single Replacement Reaction Martin Sun Purpose The purposes of this experiment were to: determine the number of moles of iron reacted; determine the number of moles of copper produced; and calculate the ratio of moles of copper to moles of iron. Materials and Methods Materials and methods for this laboratory followed those laid out in Experiment 6A on pages 56-59 of Essential Experiments for Chemistry by Morrison and Scodellaro

different types of chemical reactions using physical and chemical properties and balanced chemical equations. There are four different types of chemical reactions decomposition reactions‚ single displacement reactions‚ synthesis reactions‚ and double displacement reactions. A decomposition reaction happens when a compound breaks into two or more elements or compounds. Generally‚ for decomposition reactions heat‚ energy‚ light or electricity is needed to separate the compound. In a single displacement

Observations | Reaction Type | Complete and Balance | 1. When heated in oxygen‚ magnesium gives off a bright white flame. | combination reaction | 2Mg + O2-----> 2MgO | 2. Bubbling and fizzing occurs; the zinc appears to “dissolve” and what appears to be “steam” comes off out of container. | single-displacement reaction | Zn + 2 HCl (aq) --> ZnCl2(aq) + H2(g) | 3. Black smoke occurs | decomposition reactions | 2 (H2O2)(aq) MnO2 2 (H2O) + (O2) | 4. reddish-brown deposit

LECTURE 1 DATA TYPES Our interactions (inputs and outputs) of a program are treated in many languages as a stream of bytes. These bytes represent data that can be interpreted as representing values that we understand. Additionally‚ within a program we process this data that can be interpreted as representing values that we understand. Additionally‚ within a program we process this data in various way such as adding them up or sorting them. This data comes in different forms. Examples include: your name

Mike Morrison – SCH3U Types of Chemical Reactions Lab Intro/Purpose The purpose of this lab is to determine types of reactions with only the reactants and through observation. Through observing the experiments‚ one is able to see a visual of each type of reaction taking place and it gives them a better understanding of how chemical reactions work and what products they may form. Materials & Procedure Materials: * Wood Splints - Copper Sulfate * Sodium Sulfate - Copper

Today I observed a left total knee replacement procedure. The surgeon was Dr. O’Neil and anesthesiologist was Dr. Wells. Before the operation began‚ I followed one of the nurses to ask the patient questions to help us determine their medical history and if the patient ate anything within the last twelve hours. Once we took the patient to the O.R.‚ Dr. Wells checked the patient’s vital signs and ordered the patient to sit up and have bad posture. Dr. Wells cleaned an area of the back where he injected
