What Factors Affect Chemical Equilibrium? Introduction: In investigation 14‚ “What Factors Affect Chemical Equilibrium?”‚ the purpose was to find out which reagents caused a change in the chemical equilibrium. A deep red color was formed when Iron Nitrate [Fe(NO3)3 (aq)] was mixed with water and Ammonium Thiocyanate [NH4NCS (aq)]. The product of these two reactants was Iron Thiocyanate(FeNCS). After different trials of mixing the given reagents

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

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

Torques equilibrium‚ and center of gravity Introduction Torque is a quantitative measure of the tendency of a force to cause or change the rotational motion of a rigid body. A torque is the result of force acting at a distance from an axis of rotation. An essential thing to keep in mind is that the magnitude of the torque is equal to the product of the forces perpendicular distance and magnitude. Theory The magnitude of the torque (t) is found from the product of the force F and

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

Evaluation of the Gas Law Constant Abstract: The result of the change in volume was approximately 22 CC or 0.00084 mol. This translates into the average for the R constant being 83.8L*atm/K*mol. The four determinations ensured that the results were accurate because more than one trial helps somewhat prevent error. Approximately 0.20g of the Mg ribbon was used for these determinations. Introduction: 1. Theory If the temperature of a gas sample was held constant‚ its volume varied inversely
