write a word equation? To write a word equation‚ write the names of the reactants separated by plus signs followed by an arrow‚ and followed by the names of the products separated by plus signs. 8. How do you write a skeleton equation? To write a skeleton equation‚ write the formulas of the reactants to the left of the arrow and the formulas of the products to the right of the arrow. 9. Describe the steps in writing a balanced chemical equation. To write a balanced chemical equation‚ first write

Rate = [pic] Rate = -[pic] = -[pic] = [pic] = [pic] Notes: • The minus sign makes the value of the rate positive (since A2 < A1). • The division of each concentration by the coefficient from the balanced equation makes all of the above rates equal. • The unit of rate could be moles per liter per second (mol L-1s-1) or Ms-1 Example: Write the rate expressions of the following reaction in terms of the reactants and products H2(g) +

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

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

physicists‚ engineers‚ statisticians‚ operations research analystsand economists use mathematical models most extensively. Mathematical models can take many forms‚ including but not limited to dynamical systems‚ statistical models‚ differential equations‚ or game theoretic models. These and other types of models can overlap‚ with a given model involving a variety of abstract structures. Examples of mathematical models Population Growth. A simple (though approximate) model of population growth

properties corresponding to the idea of absolute rest. They suggest rather that‚ as has already been shown to the first order of small quantities‚ the same laws of electrodynamics and optics will be valid for all frames of reference for which the equations of mechanics hold good.1 We will raise this conjecture (the purport of which will hereafter be called the “Principle of Relativity”) to the status of a postulate‚ and also introduce another postulate‚ which is only apparently irreconcilable with

Now we will look at how the (b) factor changes the parabola‚ below is the origional graph from the top of the paper except the red line represents the same parabola with a (b) added onto it. The original equation was Y=x^2(blue line) and the new equation is Y=x^2+x(red line). The change is moving the vertex of the parabola left ½ and down ¼ but the shape of the parabola it’s self is unchanged. Here are some other examples of changing (b) in a parabola with a steady (a) As seen

Ionic Equation Going back to our first concept or topic‚ we’ve learn how to identify the Oxidizing and Reducing agent and the Oxidation as well as the Reduction. In this part of the Redox reaction or in this step‚ it is very important that you already know the Oxidizing and Reducing agent for us to find the half reaction. In this step or part‚ we will also learn how to balance using the addition of electrons in both sides if necessary. After this step we can now write the net ionic equation. There
