Lab 9: Analysis of Commercial Bleach Introduction Many common products are effective because they contain oxidizing agents. Some products‚ which contain oxidizing agents‚ are bleaches‚ hair coloring agents‚ scouring powders‚ and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (or NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized from the molecular form (Cl2) to the

NT1210 Chapter 4 Lab 4.1.1 Standards are put in place to make everything work together error free. Because Stability‚ Consistency‚ Minimization of packet errors. 4.1.2 Because the voltage used to transmit data needs only be high enough for the receiver to detect it. Making the voltage higher would make the receiver electronics more difficult. 4.1.3 Hospitals‚ security systems‚ PA & recording studios. The drawback of STP cables is that they will increase the total cost of an installation.

OLD COINS TURN TO GOLD DESIGN: Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon. Procedure: First‚ we turned on the hot plate.

Installing 70/30 copper nickel (cuni) pipe sometimes can be a test of human patients‚ mechanical knowledge‚ and dexterity. It is‚ however‚ well worth the effort‚ because once you complete the job whether you’re a novice or connoisseur of the art you gain a sense of pride for a job well done. Additionally‚ you will have confidence in knowing that your pipe will stand the test of time and vigorous challenges they’re used for. The only problem that comes with working with 70/30 cuni pipe is‚ having

Answer: Suppose two programs (NegCue and FastContext) are available and ready to run. I will put them on the same server and write a script to execute them together at the same time and record the processing time. Thus‚ the processing times of both programs will be paired for each run. By the end of the experiment‚ I will have 200 pairs of recorded processing time. Next‚ I will use paired t-test to exam rule hypothesis proposed above. Specifically‚ for example‚ let’s assume that I have recorded the
