For example, Tartaglia’s formula for a cubic equation x^3=x gives the solution as 1/√3 ((√(-1))^(1/3)+1/(√(-1))^(1/3) ).

at low acidity, since at low acidity, anything less than 1.0 x 10-3M, the effect of the hydrogen ion is negligible. To calculate the rate, the experiment will have to utilize the rate equation, which is expressed as Rate = k[H2O2]a[I-]b. At low acidity, the rate of the Hydrogen ion will not change, from our equation: H2O2 (aq) + 2I- (aq) + 2H+ (aq) → I2 (aq) + 2H2O
Christaller's Central Place Theory Introduction Central Place Theory (CPT) is an attempt to explain the spatial arrangement, size, and number of settlements. The theory was originally published in 1933 by a German geographer Walter Christaller who studied the settlement patterns in southern Germany. In the flat landscape of southern Germany Christaller noticed that towns of a certain size were roughly equidistant. By examining and defining the functions of the settlement structure and the size of

graphically, to find the k (rate constant) at 0˚ C and at room temperature, also to find the Ea (activation energy). Principles: Several different chemical kinetic principles were used in this experiment. The reaction rates of this chemical equation were determined experimentally. This then allowed the reaction mechanisms (i.e. orders of each component, rate constant, etc.). These mechanisms were ultimately determined to be compiled to form a rate law. Rate = k[A]m[B]n Integrated
to travel at a rapid rate. But exactly how fast will he be traveling at a certain time? Without this knowledge, Joe could easily splatter against the surface of the earth. In order to calculate Joe's velocity at any time, T, we use the following equation: X = Vi * T + .5 * g * t^2 Where X is the change in distance, Vi is the initial velocity, t is time, and g is the acceleration due to gravity. Since we know Joe's initial velocity was 0, and the acceleration of gravity is always 9.8 m/s^2,

Two Variable Inequalities Melissa Hillard MAT222: Intermediate Algebra (GSQ1331C) Instructor Lisa Wallace August 10, 2013 Two Variable Inequalities For this assignment the class was asked to solve problem 68 from page 539 of our textbook Elementary and intermediate algebra (Dugopolski, 2012). Problem 68 tells the number of refrigerators and TV’s that will fit inside of an 18 wheeler truck. The class is asked to write an inequality to describe the region of the graph that is shaded in
Ionic Reactions Abstract This experiment is designed to study the nature of ionic reactions, and write net ionic equations for precipitation reactions, as well as to identify spectator ions, perception reactions and solubility of different compounds. Experiment and Observations In this experiment I was using a 96-well plate to add two drops of the following solutions into seven wells in rows A through E: cobalt (II) nitrate, copper (II) nitrate, iron (III) nitrate, barium
