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

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

Introduction: The relationship of pressure to volume for a gas in a rigid container was first described in 1662 by the Irishborn scientist Sir Robert Boyle (16271691)‚ and is known as Boyle’s Law. As long as the temperature of the gas remains constant

Size‚ Temperature‚ Concentration‚ and a Catalyst on Reaction Rate Introduction: Chemical reactions can be affected by a number of different factors. Particle size‚ temperature‚ concentration of a solution‚ and catalysts play a big role in the rate of reaction‚ they determine how fast a reaction will occur. According to the collision theory‚ the rate of reaction depends on the frequency of effective collisions between particles. Every reaction is different in that they all require different conditions
