mechanical switch. It is common to use relays to make simple logical control decisions. The development of low cost computer has brought the most recent revolution‚ the Programmable Logic Controller (PLC). The advent of the PLC began in the 1970s‚ and has become the most common choice for manufacturing controls. PLCs have been gaining popularity on the factory floor and will probably remain predominant for some time to come. Most of this is because of the advantages they offer. • Cost effective for controlling

Discussion The main purpose of this lab was to synthesize four soaps and two detergents and determine which one would be the best for an environmental group to use in the event of an oil spill.1 To complete this task‚ five subgoals had to be achieved first. To find the solubility of the fats‚ oils‚ soaps‚ and detergents‚ each of them were placed into different solvents to see if they dissolved. None of the oils and fats were soluble in water (H2O)‚ sodium hydroxide (NaOH)‚ or hydrochloric acid
