Subject: Chemistry SL Title: Preparation of a salt (lead iodide) by using precipitation method. Aim: To produce 1.50 g of lead iodide‚ PbI2‚ assuming 100 % conversion‚ using 1.00 g solid potassium iodide‚ KI‚ and 0.1 M lead nitrate‚ Pb(NO3)2 solution of volume 30 cm3 and hence calculate percentage yield. Calculations: 2KI(s) + Pb(NO3)2( aq) —> PbI2 (s) + 2KNO3 (aq) Mass of PbI2 to be produced = 1.5 g Moles of PbI2 = = 0.003 Moles of KI = 0.003*2 = 0.006 Mass of KI = 0.006*166 = 1.00 g

Assignment 2 unit 3 Describe methods of producing A.C. and D.C electricity. There are two type of electric current it is known as direct current (DC). The other one is known as alternating current (AC). However‚ an electric current can be produce by moving a magnet inside a coil‚ wire‚ so the size of this induces current and it is able to increase by moving the magnet faster.
