gas required to form 1.00 x 103 g ammonia. Your Turn 2 • If you react 52.9 g of potassium chlorate (KClO3) with excess phosphorus‚ what mass of tetraphosphorus decoxide (P4O10) would be produced. KClO3 (s) + P4 (s) → P4O10 (s) + KCl (s) Answer: 36.8 g P4O10 Stoichiometry • In the real world‚ reactions do not always have 100% efficiency. • Often‚ use an excess of one of the reactants (usually the cheaper one). • Limiting Reactant – reactant that will be totally consumed. • Excess

CHE 242 Tutorial 3: Problems & Answers Week 4: Feb 2- 6‚ 2009 1. Consider a gas that occupies 1.00 dm3 at a pressure of 2.00 bar. If the gas is compressed isothermally at constant external pressure‚ Pext‚ so that the final volume is 0.500 dm3‚ what is the smallest value Pext can have? Calculate the work involved using this value of Pext. Solution For compression to occur‚ the value of Pext must be at least as large as the final pressure of the gas. P1 = 2.00 bar‚ V1 = 1.00 dm3‚ V2 = 0.500

Using the character’s thoughts‚ conversations and interactions to demonstrate the progress from disruption to accord while dramatizing the interplay of key values such as virtue and honor‚ ‘Shakesy’ presents a revenge tragedy that exists as being more relatable at a human level‚ as opposed to an epic tale. Though‚ may I might add‚ the tale is still epic in a timeless sense‚ ‘Spearesy’ uses small-scale
