Name: Name of lab partner: Date: Title: Determination of the valency of magnesium Objective: To study the quantitative relationship between the amount of reactant and products of a reaction. A known starting mass of magnesium and the measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium. Introduction: In Chemistry‚ stoichiometry is the study of the quantitative relationship between amounts of reactants and products of a reaction

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

involve the reaction of an acid and a base to produce a salt (ionic compound) and water. Acid + Base ( Salt + Water □ In this lab‚ sulfamic acid (a weak acid which contains one acidic hydrogen) will be used: H2NSO2OH(aq) + NaOH(aq) ( NaOSO2NH2(aq) + H2O(l) (Net Equation: H+(aq) + OH-(aq) ( H2O(l)) □ Titration is a process of neutralization □ Titration is commonly used to determine the concentration of an acid or base in a solution.

THE GRAVIMETRIC DETERMINATION OF SULFATE Learning Goals. 1. To determine the amount of Sulfate in an Unknown sulphate sample. 2. To perform and develop skills in precipitation Gravimetric method of quantitative analysis. DISCUSSION: Gravimetric analysis is one of the oldest analytical techniques and for this reason is referred to as a "classical method." Gravimetric procedures are usually very accurate‚ but more tedious than other methods. The only major equipment needed

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

significance of crying? And do you think the one is weak if one cries? In fact‚ crying is not gender‚ age or personality specific. From my perspective‚ crying is not a sign of weakness‚ but it is an innate ability and one of the most effective ways to reduce stress‚ release anger and express joy. It is also like a stop sign at a crossroad for you to look back and reflect on your shortcomings. Some may associate or stereotype people that cry as weak and feminine. I believe most people who cry are

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
