Description Part I: a) Include the excel graph used to determine final temperature. b) Include a table showing the calorimeter constant Part II: a) Include the excel graph used to determine final temperature. b) Include a table showing The exp specific heats determined for copper and aluminum The theoretical specific heats of copper and aluminum The % error for specific heats of copper and aluminum Part III: a) Include the excel graph used to determine final temperature. b) Include a table showing The experimental ?H neutralization The theoretical ?H neutralization % error. Limiting reagent kJ/mol (The lab procedure and my recordings directs to measure the temperature of cold water for 4 min and to include that in each of the graph. The data that I sent you only has one averaged initial temperature for cold water so you do not need and can not graph that at any point. So all graphs are simple and have one series of data and not 2 , with the y= temperature of mixture and the x= time from 1 to 5 minutes. The trendline is linear and the equation will provide the Tfinal for mixture. ) The parenthesis Is correction my professor made to the lab I added my data in the files. https://cccconfer.zoom.us/rec/play/7pV7d-6upzs3E9aVtASDAPR-W47vLqis1yIe__EOnhnjWyMBMwb0M7EQZeV3Y3uRoXpHI93wWwArx8kE?continueMode=true&_x_zm_rtaid=9pHyXaJ7TJuMN3fNhGS00A.1587163755109.510a294995745110346370bb407cd3d7&_x_zm_rhtaid=342 this link explains how to do the lab.

Description For K-323 here are the 2 parts needed. Notice that you do not need to submit purpose, procedures or data and observations or conclusions! 1. Title page (just your name and the expt number - will help me identify what I am looking at when I download the submissions and view them). 2. Answers to analysis Q - with the following modifications. You can write answers to Q by hand or in MS-Word or some combination of those. Please rewrite the Q before answering. For Q 1 and Q 2 show all working so I can see what data numbers you are using. For Q3 a) and Q 3b): For each temperature calculate 1/T and ln(rate). Show these calculated values in a table. Create a plot of ln(rate) vs 1/T. This should be an x-y scatter plot with ln(rate) on the y-axis and 1/T on the x-axis. Remember to have a title, and axis labels on the graph. Use landscape format for any kind of printing that you do with this graph. Add a best fit straight line and make sure the equation of the line is shown on the graph. You can make this graph in MS-Excel, or Logger pro or other graphing software you may have. Remember you can download Logger pro from Canvas - you will find it in the modules section under Expt S-201 with instructions on how to install it. For Q3c) Use the slope of the line from the graph to calculate the activation energy in kilojoules per mol (kJ/mol). Data 1 room temperature T i = 21.0 c Ti = 2:30 min to sec? Tf = 2:40 min to sec? Mean? 2) in high temperature Ti = 40.0 c Tf =28.0 c ti =2:10 min to sec? Tf= 2:16 min to sec¿ Mean? 3) In low temperature Ti= 5.30 c Tf= 10.6 c Ti= 3:40 min to sec? Tf= 3:51 min to sec? Mean?
Description Replacement lab: Cobalt Chloride and LeChatlier?s Principle http://chemcollective.org/vlab/85 Click on the words "Cobalt Lab" (on the right side just above WorkBench 1) which will further explain the lab problem within this assignment. After following the directions given there, create a Word document where you will list the following 4 items: Consider the chemical reaction: Co(H 2O) 6 2+(aq) + 4Cl -(aq) <==> CoCl 4 2-(aq) + 6H 2O(l) 1. Predict the effect of removing chloride ions. In which direction will the above reaction shift? 2. Predict the effect of adding HCl. In which direction will the above reaction shift? 3. Is the reaction endothermic or exothermic? 4. The environmental temperature for this lab is 25 oC. Calculate the K value at this temperature as well as the K value at any other temperature of your choosing between 0 and 100 0C. Report this new K value and at what temperature it was found. Hint: You can compare these two K values to help verify your determination of endothermic or exothermic for the above reaction. Submit the Word document
Description Which of the items below would be considered the densest? (Show your step-by-step work for calculating density of each, in the units of g/mL, to support of your final answer) A piece of wood with a volume of 2.5 L and a mass of 12.5 kg A ball with a volume of 139 mL and a mass of 93 g A tire with a volume of 2.12 L and a mass of 4.22 x 104 mg A wire with a volume of 3.91 x 10-7 L and a mass of 7.93 x 10-1 ng A block of metal with a volume of 1350 mL and a mass of 1.29 x 103 g 2. Potassium has two naturally occurring isotopes. The masses (amu) and percent abundances of the two isotopes are given below. Show your work, and calculate the average atomic mass of the element in amu units. 3.Name the steps of the scientific method and apply them to an everyday problem you might solve using the method. Be detailed with your answer, and explain each step of your problem. Submit your answers in a single Microsoft Word document. Be sure to cite and reference using APA guidelines when quoting or paraphrasing material. At a minimum, you should cite the textbook when answering question 3.
Description Q1.1 – Hierarchical organization and chemical complexity can be exemplified by the Saguaro desert as the ecosystem. Provide an example for each of the other six hierarchies leading up to this ecosystem. Energy Conversion Processes Q1.2 – The Second Law of Thermodynamics states that all spontaneous processes in the universe tend toward the dispersal of energy in the absence of energy input, which leads to death for a living organism. What are the two sources of energy for an autotroph over a 24 hour period and what are the chemical processes involved in each? Structure and Function of Water Q1.3 – Planetary scientists are searching for planets with water because it will support our chemical life. Name three properties that make H2O uniquely critical to life on Earth. Biological Membranes Q1.4 – Flippases are enzymes that catalyze the flip-flop movement of phospholipids in a membrane bilayer. What property of membranes contributes to the energy barrier that flippases lower in order to increase the rate of phospholipid flipping?
