temperature before and after mixing was recorded and included in tables. When the experiments were completed analysis was performed using the laws of thermodynamics. The data collected was used in equations to find theoretical values for final equilibrium temperature. The theoretical values were compared with those measured during the experiment. The total average percent difference between the measured final temperature and the theoretical final temperature is less than 5.0%. This low deflection

element through a number of chemical reactions including redox‚ metathesis‚ decomposition‚ and single replacement reactions‚ the cycle will be complete once solid copper is recovered. Attempting to create a diagram of the ecological cycle of copper must require knowledge about copper’s chemical cycle first‚ which may then allow for the development of possible solutions to copper pollution.

Abstract The photocatalytic degradation of phenol has been tested primarily with titanium dioxide (TiO2) either alone or in combination with other materials. In this work‚ Mg/Al hydrotalcites prepared by two methods using inorganic (HC) or organic (HS) chemical reagents‚ along with mixed oxides produced by calcination of these products (HCC and HSC) were mixed with titanium isopropoxide to obtain hydroxide-TiO2 compounds (HCC-TiO2 and HSC-TiO2) to test their photocatalytic activity compared with

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

com/articles/2008/06/06/business/air.php The Principle of Market Equilibrium The equilibrium price is the price at which the quantity demanded of a good or service is equal to the quantity supplied. The Principle of Market Equilibrium states that perfectly competitive markets are always moving toward said equilibrium. If the price is too high or low‚ there will be a surplus or shortage‚ respectively‚ which will drive the price towards the “market-clearing” equilibrium price. When there is a shift of the demand and/or

LONG-RUN EQUILIBRIUM OF A FIRM UNDER PERFECT COMPETITION In the long run‚ a firm in the perfectly competitive market can earn only normal profit. So‚ the profit maximization under long run is: (1)Necessary condition P=LMR=LAR=LMC=LAC (2)Sufficient condition Slope of MC > Slope of MR We can establish this condition from the following analysis. In the above diagram for any market price OP1 the existing firms can earn supernormal profit as for the equilibrium output level OQ1. The average

DISCUSSION In this experiment‚ we will extract plasmid DNA that carrying pKan and pAmp from E. coli that have been cultured overnight in LB media containing antibiotic kanamycin and ampicillin respectively. So‚ the DNA that will be introduced later will make the bacteria resistance to antibiotic kanamycin or ampicillin. A plasmid is a small‚ circular‚ double stranded DNA molecules and cloning vector that are widely used for recombinant DNA technology. It can be physically separated from chromosomal

Saccharin is the ingredient thought to have the biggest interference and was used as the experimental basis2. Instruments: UV/VIS spectroscopy was used to analyze the absorption spectra of the many solutions in this experiment. It was chosen for its ability to collect absorption data quickly and efficiently. A Target Factor Analysis program was used to
