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

When doing research nurses have come up with theories to expand nursing practice and these theories help ideas to be composed. Theory backs and puts forward research problems‚ research discoveries confirm or disprove theory explanations‚ as stated by Borbasi and Jackson‚ (2012).The research article that I have chosen for this assignment is from International Journal of Nursing Practice. It is a qualitative study that was written by King and Walsh‚ (2007) and the topic is ‘I think PCA is great‚ but

able to determine whether a cost is fixed or variable is vital to the understanding of overhead loading and cost behavior. A fixed cost is unchanged with a change to the cost driver. (Horngren‚ Sutton‚ and Stratton p.46) Which means that a fixed cost does not rise with the change is production of your product. A good example of a fixed cost is rent. No matter how many widgets you make (within a relevant range) your rent will not increase. A variable cost‚ on the other hand‚ does change with the
