Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods

Sugar is fairly elastic demand because there are only small changes in quantity purchased if the price of sugar increases without government’s subsidy. This is because sugar is a necessity to everyone and sugar has no much close substitute

Supply and Demand Simulation ECO/365 Supply and Demand Simulation In the supply and demand simulation a neighborhood called Atlantis is given for the setting. Atlantis is a small city with open spaces‚ low population‚ and a low crime rate. There are plenty of sidewalks and street systems for easy access to the highway. The housing in Atlantis is detached homes and apartments. The supply and demand simulation consists of microeconomics and macroeconomics. The simulation presents shifts in the

Price Elasticity of Demand is used to measure the responsiveness of the quantity demanded to the change in price. It is measured by the percentage of change in quantity over the percent change in price [% ∆ in quantity demanded/ % ∆ in price]. Price elasticity of demand (PED) does not have any units as all the units cancel out while calculating it. Also‚ │PED│ is usually negative because the value of quantity demanded will always be inverse to its price (i.e. when price gets high‚ quantity demanded
