the following sets of information write an equation. Assume that each set of information describes a linear relationship. Assume Y is the variable measured on the vertical axis and X is the variable measured on the horizontal axis. Write all equations in slope-intercept form. a. When X = 10‚ Y = 5 and when X = 7‚ Y = 2. Answer: First find the slope of the line: slope = rise/run = (5 – 2)/(10 – 7) = 1. Then‚ write the equation in general form: Y = mX + b and substitute

PROPORTION METHOD The proportion method is used in both of these expressions. A proportion is an equation that says that two ratios are equivalent. The use of cross multiplying is in use in both expressions as well. I believe the first expression (#56) uses the extreme-means property; the product of the means is equal to the product of the extremes. #56.

reactors‚ or nature‚ can be described by reaction equations. Knowing the skeletal reaction equation‚ the reactants and the products are also known‚ but for quantitative predictions‚ the reaction equation needs to be balanced. A balanced equation is an equation or a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products. (1) From a balanced equation‚ the mole relationship can be figured out. The amount

The reaction of copper metal with silver nitrate solution is a single replacement reaction‚ represented by the following unbalanced equation: Cu(s) + AgNO3(aq) → Cu(NO3)2(aq) + Ag(s) The values of the coefficients can be determined experimentally by measuring the mass of copper wire that reacts with

Chapter 2: Linear Functions Chapter one was a window that gave us a peek into the entire course. Our goal was to understand the basic structure of functions and function notation‚ the toolkit functions‚ domain and range‚ how to recognize and understand composition and transformations of functions and how to understand and utilize inverse functions. With these basic components in hand we will further research the specific details and intricacies of each type of function in our toolkit and use

Introduction The purpose of this experiment is to determine the rate equation for the “Iodine Clock Reaction” experiment. The experiment will consider the equations 〖2I〗^-+S_2 O_8→2〖〖SO〗_4〗^(2-)+I_2 and I_2+2〖S_2 O_3〗^(2-)→2I^-+S_4 O_6 in order to determine the rate law of Rate=k[〖〖S_2 O_8〗^(2-)]〗^a 〖[I^-]〗^b by using the experimental data to calculate the values of exponents a and b as well as the rate constant k.
