CH 127 – Chem 2 Lab Determination of an Equilibrium constant Goals The purpose of this experiment is to determine the equilibrium constant for the reaction Fe3+(aq) + HSCN(aq) –>FeSCN2+(aq) + H+(aq). The equilibrium constant expression Kc for Reaction is kc=FeSCN2+[H+]Fe3++[HSCN] Procedure *Preparation of the Beer’s law plot Prepare five solutions of FeSCN2+(aq) of known concentrations between 1x10-5M and 1x10-4M by diluting various volumes of 4.62x10-4 HSCN.

Rational Systems of Organizations In modern society‚ the things that we encounter and demand in our everyday lives‚ such as technology‚ the internet‚ trade‚ stocks‚ and manufactured products‚ all contribute to the need for formal organizations. A significant part of our lives is governed by these institutions because we function as their consumers or employees‚ or in the case of a CEO‚ who may classify them as business partners or competitors.

After the attack‚ not only were Muslim- Americans suddenly seen as evil by the American people‚ but a program was initiated which required immigrants from specific countries to register with the government in order to screen for any risks to the nation.

Abstract Equilibrium is the condition of a system in which competing influences are balanced. In the experiment we measured and experimented for the equilibrant force‚ conditions and center of gravity. Our results showed consideration as to disregarding other forces than weight and tension. 1. Introduction Equilibrium is a state of balance in which it is a condition where there is no change in the state of motion of a body. Equilibrium may be observed on objects which are at rest and also

Introduction: Chemical equilibrium is when the concentrations of the reactants and products have reached a state where reactions occurring in one direction are at the same rate of reactions occurring in the opposite direction. This process‚ called dynamic equilibrium‚ is the main subject of Le Chatelier’s Principle. Le Chatelier pointed out that if a system at equilibrium is subjected to a stress that momentarily causes the system to be not in equilibrium‚ a spontaneous change will occur to

Explain 2 types of barriers to entry which can prevent potential competitors from entering an industry Monopoly and oligopoly both are types of barriers to entry which can prevent potential competitors from entering an industry A barrier to entry is anything that prevents entry when entry is socially beneficial A monopoly possesses high barriers to entry. This deters other firms from entering the market and thus allows the monopoly to keep their status as a single seller of unique product
