CHEMICAL REACTIONS: ACID-BASE BUFFERS Short Overview Acids and bases represent two of the most common classes of compounds. Many studies have been done on these compounds‚ and their reactions are very important. Perhaps the most important reaction is the one in which an acid and base are combined‚ resulting in the formation of water (in aqueous solution) and a salt; this reaction is called neutralization. A buffer solution is a solution that contains both an acid and a salt containing

The third part Section C 5-25% of sodium chloride was prepared by the instructor. For each percent concentration of sodium chloride a 25 mL was prepared. Weighing the graduated cylinder before and after the sodium chloride was transferred the density were calculation. Pre- Laboratory Questions: 1.

7 Ordinary Differential Equations Matlab has several different functions for the numerical solution of ordinary differential equations. This chapter describes the simplest of these functions and then compares all of the functions for efficiency‚ accuracy‚ and special features. Stiffness is a subtle concept that plays an important role in these comparisons. 7.1 Integrating Differential Equations The initial value problem for an ordinary differential equation involves finding a function

While the ultimate goal is the same‚ to determine the value(s) that hold true for the equation‚ solving quadratic equations requires much more than simply isolating the variable‚ as is required in solving linear equations. This piece will outline the different types of quadratic equations‚ strategies for solving each type‚ as well as other methods of solutions such as Completing the Square and using the Quadratic Formula. Knowledge of factoring perfect square trinomials and simplifying radical expression

Accounting Equation Paper ACC 300 Accounting Equation The accounting equation is the basis of double entry accounting. The equation places debits and credits on each side of the equation with a balance on each side being required. The debits are accounted for as assets‚ while the credits fall under liabilities and shareholder equity. (Kimmel‚ Weygandt‚ and Kieso‚ 2011) The equation looks like: Assets = Liabilities + Shareholder Equity. A system of journal entries that show a debit and credit for

quadratic equation is an equation that has a second-degree term and no higher terms. A second-degree term is a variable raised to the second power‚ like x2. When you graph a quadratic equation‚ you get a parabola‚ and the solutions to the quadratic equation represent where the parabola crosses the x-axis. A quadratic equation can be written in the form: quadratic equation‚ where a‚ b‚ and c are numbers (a ≠0)‚ and x is the variable. x is a solution (or a root) if it satisfies the equation ax2 +

MSG or monosodium glutamate is a sodium salt of glutamic acid which can be naturally found in many common foods that are rich in protein content such as dairy products‚ meat‚ vegetable and mother’s milk. In fact‚ our own bodies do produce glutamic acid via Krebs cycle during metabolizing food. Glutamate is the most abundant naturally occurring non-essential amino acid (Ninomiya‚ 1998) and it is a very common part of our diet. In the food industry‚ MSG is widely used as a flavor enhancer. It is responsible
