In determining the direction of a chemical reaction we must rely on an understanding based on a number of factors, and contributions that are not always easy to assess. Although the assessment is prone to error, but it is usually reliable where it seems reasonable to try, and that is certainly to answer ignorance. In predicting chemical reactions there are several known factors such as, if the free energy of a reaction is known, then there is no problem predicting a chemical reaction. Then if only enthalpy changes are known, then predictions usually apply to room temperature but are more or less reliable as well for higher temperatures. If the reaction occurring in the solution and the oxidation potential of the involved compound is known then the prediction is relatively simple, and this oxidation potential buys a rough guide for possible reactions in the absence of a solvent. If the equilibrium constant is known, relating to ΔG0 = - RH in K gives us a change of free en...

CHEMICAL REPORT "Redox Reaction" CHAPTER I PRELIMINARY A. Purpose: In this activity will be studied spontaneous redox reactions and not spontaneous B. Platform Theory: Reduction is the acceptance of electrons or decreases in oxidation numbers, whereas oxidation is the release of electrons or an increase in the oxidation number. The redox reaction is a combination of the simultaneous reduction and oxidation reactions. There is no electron discharge event (oxidation reaction) without an electron capture event (reduction reaction). Redox reactions may be either spontaneous or spontaneous. The spontaneity of a redox reaction can be determined using a voltaic series. The order of the metals in the volt series is: K-Ba-Ca-Na-Mg-Al-Mn-Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H2) -Sb-Bi-Cu-Hg-Ag-Pt-Au The metals next to k2H2 are active metals (strong reducing agents) while the metals on the right H2 are less active (weak reductors). The more to the left the re...

Stoichiometry is the basic chemical calculation that states quantitative relation of chemical formulas and  chemical equations. Here are the materials you need to know to understand, from the concept of moles and molar masses, empirical formulas and molecular formulas, basic stoichiometry of solutions and ideal gases, and the writing and equalization of reactions, with examples of problems and discussions.  In chemistry, chemical reactions are frequently written as an equation, using chemical symbols. The reactants are displayed on the left side of the equation and the products are shown on the right, with the separation of either a single or double arrow that signifies the direction of the reaction. The significance of single and double arrow is important when discussing solubility constants, but we will not go into detail about it in this module. To balance an equation, it is necessary that there are the same number of atoms on the left side of the equation as the...
