The Solubility of Potassium Nitrate Aim: The aim of this experiment is to find out by how much the solubility of potassium nitrate into distilled water increases when the solution is heated‚ and if yes‚ by how much. Hypothesis: According to data on the internet‚ 3.75 × 10¹ moles of potassium nitrate dissolve in 100g of water. I believe this information may be correct. I also believe that as the solute is absorbing outside heat‚ the energy is increased causing it to dissolve both faster‚ with

Kim Dec. 15‚ 2011 Abstract Two experiments were conducted to figure out the value of the formation constant of tetraamminecopper(II)‚ Kf‚ with different methods and which experimental method produces more accurate result. One was electrochemistry using a Daniel cell and the other one was spectrometry by estimating concentration of complex solution using a calibration curve. The formation constant of cupric ammine complex Cu(NH3)42+‚ Kf‚ came out with 1.93x10^15 using electrochemical cell method

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚

and iodine react. However reaction (4) does not determine the amount of iodine produced‚ it only determines when iodine is present in solution. Essentially reaction (3) is used to determine how much iodine is produced. To understand how the rate constant (k) is temperature dependent‚ another set of data can be recorded

Spilled Salt By: Barbara Neely Something I liked about this story was that it had a realistic plot. It’s completely possible for a mother to have her son go to jail and come back unexpected. This actually happened to someone I knew‚ they were in jail for raping a girl‚ when they really didn’t and his mom had a hard time dealing with him being back from jail when really she just wanted him to leave her life completely. Something I didn’t like about the story was the character of the mom‚ she seemed

Ben Snyder Constant Velocity Lab To the Left: The Position Vs. Time graph Red: Run #1 Blue: Run #2 Green: Run #3 Purpose: To find what the slope of a position vs. time graph represents. Q.1) The Slope of the second run is greater than the slope of the first run. The first piece of evidence is in the data calculations themselves. In run number 1 the calculated slope 15 m/s which is considerably less than the slope of the second run which was at a swift 0.27 m/s. Also as you can clearly see

Solubility and Stoichiometry I. Introduction The first purpose of this experiment is to apply solubility rules to choose two of eight given reactants to do a precipitation reaction. The second purpose is to use stoichiometry to calculate how much of a reactant will be used in a precipitation reaction‚ assuming that the amount of product is given‚ and to figure out the actual yield vs. the theoretical yield and to calculate the percent yield. The other purpose of this experiment is to practice the

He loved South Africa deeply and did everything to win its freedom. In this poem‚ “It Is the Constant Image of Your Face”‚ he closes the first stanza by saying “my land takes precedence of all my loves”. This was his passion. While he was in prison‚ news broke that South Africa had been banned from the 1964 Tokyo Olympics as he had campaigned for
