In order to first perform the reaction‚ 1.5 mL of 4-methylcyclohexanol was added to a pre-weighed 5mL conical vial. The conical vial was then weighed to find the actual mass of 4-methylcycloheaxanol. Then‚ 0.4mL of 85% phosphoric acid was added to the conical vial using a plastic pipet. Six drops of concentrated sulfuric acid was then added to the vial using a glass pipet. A spin vane was then added before adding the Hickman head‚ water condenser and a drying tube packed with calcium chloride to

CHAPTER 4 Objectives: 1. Define consciousness.--------- 2. Appreciate the role of the circadian rhythm. 3. Describe the stages (5) of sleep including the sequence of the stages. The development of the electroencephalograph led to dramatic increases in what is known about sleep. When electrodes are attached to the face and scalp of sleepers‚ different patterns are produced on the graphic record called the electroencephalogram or EEG. The patterns vary in frequency and amplitude of the waves

The final compound which I am going to look at is 4-aminobenzenecarboxylic acid. The compound is also known as 4-Aminobenzoic acid. The molecular and structural formula of the compound is C7H7NO2 which means that the compound consists of seven carbon atoms attached to seven hydrogen atoms along with one nitrogen atom and two carbon atoms attached as a carbon-oxygen double bond. The displayed formula for the 4-aminobenzenecarboxylic acid compound is shown and it shows the formula in a ring form therefore

It would be impossible to categorize all potential causes for alarms in all existing network systems however‚ understanding some common alerts and categories is essential for any network manager. Many Network Management Systems have a log and event manager that collects data

Assignment Week 4 Chapter 11 20. A parallel RL circuit has values of IL = 240 mA and IR = 180 mA. Calculate the magnitude and phase angle of the circuit current. It=√ IL^2 + IR^2= √ 240mA^2 + 180mA^2= 0.3 x 10^-3= 300mA θ= tan^-1(-IL/IR)= (-240mA/180mA)= -53° 300mA∟-53° 22. Calculate the total impedance for the circuit shown in Figure 11.38b. It= √IL^2 + IR^2= √800mA^2 + 120mA^2= 0.808949 x 10^-3= 808.95mA Zt= Vs/It= 120V/808.95mA = 148Ω θ= tan^-1(-IL/IR)= (-800mA/120mA)= -81.5= 82° 148∟82° 24
