Aim: To find out the mass of Iron (II) sulphate each ‘Iron tablet’ contains Background Knowledge: ‘Iron tablets’ are prescribed to patients suffering from anaemia. They contain 200mg (0.200g) of iron (II) sulphate FeSO4 We are going to analyse iron tablets to find out how much Iron (II) sulphate they contain. The procedure we will use is a REDOX reaction‚ by oxidising the Fe2+ contained in the Iron (II) sulphate to Fe3+. We will use potassium manganite (VII) as the oxidising agent. The active part

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Wind‚ Sand‚ and Stars: A Book Review American author John Green once gave some advice to an aspiring writer; “Don’t make stuff because you want money‚ it will never make you enough money.

Last Friday in class‚ we wrote a CTA about Emily Dickinson’s poem and had an ORB discussion. For the ORB project‚ our group read Salt to the Sea by Ruta Sepetys. The book is about four characters‚ who are the refugees from the World War II‚ and how they interact with each other. To be honest‚ in class‚ I did not raise any deep‚ philosophical question about what I was doing. I simply followed what I was asked to do. However‚ when I went back home‚ sitting in front of my green desk‚ having a document

stories that contain the eight formal elements she identifies as prerequisites for the genre. Chief among them is the element of betrothal––or‚ as it is more colloquially understood‚ the “happy ending.” When considering Patricia Highsmith’s The Price of Salt‚ there is some room for debate as to whether the book can truly be called a romance. The novel details the courtship of two women in the 1950’s––Carol Aird‚ a wealthy homemaker in the midst of an ugly divorce‚ and Therese Belivet‚ a naïve‚ struggling

Purpose: The purpose of this lab is to identify the presence of cations and anions in four unknown solutions by identifying whether they are copper‚ silver‚ iron‚ or chloride ions which is done by adding sodium hydroxide‚ solid copper‚ silver nitrate‚ and potassium thiocyanate to the solutions and analyzing the chemical reactions. Introduction: Chemical change‚ unlike physical change is the change in the composition of a substance rather than simply its shape‚ size‚ or state (Marie‚ 2015). Signs

Investigating Stoichiometry with Carbonic Acid Salts Problem: Testing the actual yield versus the theoretical yield of NaCl when HCl is titrated into Na2CO3 and NaHCO3. When 0.15g of both NaHCO3 and Na2CO3 are titrated with HCl‚ then 0.165g of NaCl should form from the NaHCO3‚ and 0.104g of NaCl should form from the 0.15g of Na2CO3. Procedure: Weigh 2 samples of 0.15g of dried unknown each‚ and dissolve each into 50mL of distilled water. Add 0.5 to 1mL of bromocresol green indicator until the
