1. Briefly explain the following: a. Chemical equilibrium- Chemical equilibrium is the state of a reaction when the concentrations of the reactants and products are no longer changing and remain constant. The forward reaction proceeds at the same rate as the reverse reactions making them equal. This type of equilibrium is also named dynamic equilibrium or a dynamic process. When a reaction has reached its chemical equilibrium‚ the constant K value will remain constant unless the temperature changes

The Golden Ratio The golden ratio is a number used in mathematics‚ art‚ architecture‚ nature‚ and architecture. Also known as‚ the divine proportion‚ golden mean‚ or golden section it expresses the relationship that the sum of two quantities is to the larger quantity as is the larger is to the smaller. It is also a number often encountered when taking the ratios of differences in different geometric figures. Represented mathematically as approximately 1.618033989‚ and by the Greek letter Phi

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation
