Good evening ladies and gentlemen and welcome to the Apex Club of 2013‚ my name is James Bajjada and tonight‚ I shall discuss and introduce the notion of Australia as a global citizen and the role our country has played in promoting World wide peace‚ security and equality. What is a Global citizenship? Global Citizenship is about understanding the need to tackle injustice and inequality‚ and having the desire to do so. It is about valuing the Earth as precious and unique‚ and safeguarding the future

Mole Ratio of a Chemical Reaction: Copper & Silver Nitrate Lab #4 OBJECTIVE In this experiment‚ you will determine the number of moles of reactants and products present in the reaction of copper and silver nitrate‚ and calculate their mole-to-mole ratio. The mole-to-mole ratio relating to the disappearance of copper and the formation of silver metal will be used to write the balanced equation for the reaction. The reaction of copper metal with silver nitrate solution is a single

Mole Fraction Return to Solutions Menu The mole fraction is: moles of target substance divided by total moles involved The symbol for the mole fraction is the lower-case Greek letter chi‚ χ. You will often see it with a subscript: χsolute is an example. Example #1: 0.100 mole of NaCl is dissolved into 100.0 grams of pure H2O. What is the mole fraction of NaCl? Solution: 100.0 g / 18.0 g mol¯1 = 5.56 mol of H2O Add that to the 0.100 mol of NaCl = 5.56 + 0.100 = 5.66 mol total Mole fraction
