combusts as: CH4(g) + O2(g) ---> CO2(g) + 2 H2O(g) Net Ionic Equations Net ionic equations are equations that show only the soluble‚ strong electrolytes reacting (these are represented as ions) and omit the spectator ions‚ which go through the reaction unchanged. When you encounter net ionic equations on the test‚ you’ll need to remember the following solubility rules‚ so memorize them! Also keep in mind that net ionic equations‚ which are the bare bones of the chemical reaction‚ usually take

The concentration of water does not change to any considerable extent during the reaction and does not appear in the rate law. This experiment was an intermediate event and such a reaction is most often called hydrolysis and is represented by the equation: C4H9Cl + H2O C4H10O + HCl. Experimental A burette was rinsed with 0.25M sodium hydroxide. The burette was drained and refilled with the sodium hydroxide solution. 100mL of isopropyl alcohol/water solvent was placed in a 100 mL volumetric

EMSE 6020: Decision Making with Uncertainty HOMEWORK 4‚ SUMMER 2013 Instructor: Joost Santos DEADLINE: June 27‚ 2013 Problem 1: (2 pts) Two contractors (1 and 2) placed a bid on a road construction project. They were each asked to provide percentile estimates of the time (x‚ in years) it would take the road to undergo a major maintenance after its completion. We seek to maximize this time variable x‚ as larger values imply better structural integrity as well as cheaper projection of the net

of -1. Straight Lines: Equation of a straight line is y = mx + c‚ where m = gradient‚ c = y-intercept. The equation of a line‚ if we know one point and the gradient is found using: (y - y1) = m(x - x1) (If given two points‚ find the gradient first‚ and then use the formula.) Two lines meet at the solution to their simultaneous equations. Note: When a line meets a curve there will be 0‚ 1‚ or two solutions. 1. Use substitution to solve the simultaneous equations 2. Rearrange them to form a quadratic equation
