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

Why Calcium nutrition is so important? Calcium is one of the most important minerals that body needs in order to function properly and to maintain optimal health‚ especially when it comes to bone. Calcium is used in so many ways throughout the body. It is necessary for contracting muscles‚ forming and strengthening bones and teeth‚ conducting nerve impulses throughout the body‚ blood clotting‚ maintaining a normal heart beat as well as other important processes. Calcium performs a number of basic

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

South African. His activist life likens him to a crusader for his country. A knight on duty for a mistress; and this has so often appeared in his poetry. 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

Error Analysis: Force constant in springs Maria Loraine Menorca National Institute of Physics‚ University of the Philippines Diliman‚ Quezon City lorainemnrc@gmail.com Abstract This experiment aims to fully understand the analysis of possible errors in the measurement of the force constants in different spring systems. Springs can be utilized to store and release energy. According to Hooke’s Law‚ the response of a spring to external forces is characterized by the equation F = -kΔx. In this experiment

______________________ Evaluation of the Gas Law Constant Objectives In this experiment‚ we will determine the Ideal Gas Constant‚ R‚ which relates the number of moles of gas present to its volume‚ pressure and absolute temperature. Background To see how "R" was derived‚ we must look at the proportionalities defined by the other fundamental gas laws. For example‚ Charles’ Law showed us that the volume of a gas sample is proportional to its absolute temperature at constant pressure. Thus V ∝ T abs . In addition

Title of Experiment 12: The Effect of Ionic Strength on the solubility of an Electrolyte Aim: The purpose of this experiment was to determine the thermodynamics variable of enthalpy‚ ∆H for the dissolution reaction of boric acid in water. The solubility of boric acid was measured over a range of various temperatures by finding out at what temperature crystallization began for solution of different molarities. A graphical relationship between the natural logarithm of molal concentration and the inverse
