Lab Report: Scientific Method Your Name: Taylah Harness Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? The goal for this lab is to be able to get the boiling water’s temperature to increase by adding table salt. The problem it is trying to explain is‚ how does table salt affect the boiling temperature of water? does it increase or decrease? or does it stay the same? Hypothesis After reading the lab

May 30‚ 12 Date Submitted: June 6‚ 2012 Name: 2968 Instructor: Reid A hydrate was given to our group and the identity of the hydrate was unknown. The lab workers were told to determine the identity of the unknown hydrate. The identity of the hydrate could be determined by calculating the hydrate’s percent of water. So the lab workers set out to determine the water percent of the unknown hydrate. The percent of any compound or element can be found by using a certain formula. This formula

Calorimetry To determine the specific heat of a metal and its approximate atomic mass. To determine the heat of neutralization for a strong acid-strong base reaction. To determine the quantity and direction of heat flow for the dissolution of salt. Post Lab Questions and Answers: 1. In parts A and B in‚ the calorimeter‚ although a good insulator‚ absorbs some heat when the system is above room temperature. Is the reported value for the specific heat of the metal too high or too low? Explain.

TITLE: Water Based Drilling Fluid Analysis EXECUTIVE SUMMARY: Analysis of drilling fluids is essential to their performance. In this laboratory exercise the aim is to test three drilling fluid samples for; density and rheological properties‚ Fluid loss‚ chemical analysis i.e. testing pH‚ alkalinity‚ testing for chloride ions‚ calcium carbonate‚ calcium‚ bentonite; also determining the amount of solids present in the samples as well as volumes of oil‚ water and solids contained in the sample‚ and

to be composed of 5 % organic material 25% Air 25% water‚ 45% of inorganic material which could be either sand‚ silt‚ or clay. Being almost a majority these 3 categories have a lot to do with soil’s relationship with its second most important component‚ water. It has been measured and figured that sand is the larger of the 3 aggregates having the greater diameter being called a coarse sand which we know to not hold water very well. A soil whose aggregates are within a fine and coarse texture is

stre ngth of cement by applying Compressive and Tensile tests on Cement-Sand mortar. Standards: ¾ Compressive strength of cement using mortar cubes: B.S.12 – Part 2 ASTM : C 109 ¾ Tensile strength of mortar using briquettes: B.S.12 – Part 2 ASTM : C 109 General Discussion: In these tests (Compressive and Tensile tests) we measured the mechanical strength of the hardened cement. These tests are done on cement – sand mortar and not on the hardened cement itself‚ the r eason of not using

Michael Castelli Keegan Bauman Potato Lab Dr. Peano Block 1 Introduction: Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis‚ which is a transport mechanism. In this lab the problem being tested was what environment affects the mass of the potatoes the most. The independent variable is the environments used salt‚ water and iodine solution. The dependent variable is the mass of
