equilibrium constant Kc for the reaction. In this experiment‚ I will study the equilibrium properties of the reaction between ethanoic acid‚ otherwise known as acetic acid (CH3COOH) and water (H2O): CH3COOH(aq) + H2O(l) CH3COO-(aq) + H3O+(aq) When solutions containing ethanoic acid and water are mixed‚ they react to some extent‚ forming CH3COO- and H3O+. As a result of the reaction‚ the equilibrium amounts of CH3COOH and H2O will be less; for every mole of CH3COO- formed‚ one mole of CH3COOH and one

Sample Written Task 1 Criterion A The rationale seems to be a few words over the 200-300 word limit‚ clocking in at 303 words total; not that bad but it needs to stay within the word limit. The rationale also doesn’t give a clear cut purpose as to why he is doing this. He does give some background information about why exactly he chose this exact topic for his written task‚ but he doesn’t tell us what exactly he’s trying to do and what the task is about.

Number‚ n | Numerator‚ N | 1 | 1 | 2 | 3 | 3 | 6 | 4 | 10 | 5 | 15 | Numerator Numerator Row Number Row Number The equation for the numerator can be derived by using quadratic regression on a graphing calculator. The equation is; y = .5x2 + .5x. This translates into; M=.5n2+.5n‚ where n=row number‚ and M=numerator. This means that any numerator from a certain row number can be found by using this equation. For example‚ to find the numerator of the sixth

Original Article EDITORIAL Airlines‚ Emissions and Europe’s Sensible Plan Published: February 26‚ 2012 The carbon dioxide from airplanes accounts for about 3 percent of the world’s greenhouse gas emissions‚ a share projected to go up as air traffic rises. The European Union is now requiring airlines that fly into or out of Europe to pay a fee for these emissions. This is a smart response to an urgent problem. The United States and the other nations opposing the program should either come

OPA Circle Style The three circles; O‚ P and A intersect to create an interesting investigation regarding circles. Since this is a Calculus course‚ the investigation does have to deal with Derivatives. The most important and the focus of this portfolio is the line segment‚ OP’. Using the given diagram above‚ this investigation consists of finding the general equation for discovering OP’. The values that are given are that r‚ is the radius of C1 and C2. OP and AP are the radii of C3. This information
