It's important that your lab equipment is set up and calibrated correctly.Calibrationinvolves making sure the scale isn't off by a certain amount, that zero really means zero. For example, we use scales and balances to measure the mass of an object in kilograms, grams, or pounds. But it...
Another advantage of the offset boring head is the fact that a graduated micrometer collar allows the tool to be moved accurately a specified amount (usually in increments of 0.001) without the use of a dial indicator or other measuring device. NOTE: On some boring heads, the reading on t...
If a graduated cylinder wasn't calibrated correctly, how would that affect the results of a measurement? Show how you could prepare the given substance from propan-1-ol. Briefly explain how a mass spectrometer works. What kinds of information does one obtain from the instrument? What physical ...
9.To prepare a buffer, use 25 mL graduated cylinder to add 10 mL of 0.10 M HC2H3O2 and 10.0 mL of 0.10 M NaC2H3O2 to a 100 mL beaker. 10.Measure the pH of the buffer solution and record. 11.Add 1 drop of 0.10 M HCl, stir, measure and record the pH. 12.Repeat step 11 for...
Electrochemical cells are part of electrochemistry. Explore the parts of an electrochemical cell, the definition of an electrochemical cell diagram, the functions of the anode and the cathode, and how to make a homemade battery. Related to this Question ...
When a metal has a low melting point you can, of course, just melt it and pour it into a graduated cylinder to measure its volume. But gallium, if there was any of it in this alloy, tends to "wet" a wide variety of other substances. So, presuming there was gallium or something th...
I still know how to use both and I could use either if I wanted or needed. But I don’t want to or need to use a typewriter, electric or manual, or use a slide rule, period. Such is a Third Grade Brain’s approach to reading. It’s a typewriter. As long as it accomplishes ...
above which a narrow graduated stem is located. The water to be tested is filled into a graduated cylinder, into which the hydrometer is then gently lowered until it floats freely, without moving. The density is then read off from markings on the graduated stem, i.e. where the water surfa...
These holes must be drilled (size to allow 1/4" tapping) perpendicular to the steel cylinder. Balance a steel ruler on the cylinder at the drill point and bring down the Drill Press (Turned Off). If the drill is in the right alignment the steel ruler will be parallel to the drill tab...
How does the scientific approach to knowledge differ from other approaches? How is chalcone used in medicinal chemistry? If a graduated cylinder wasn't calibrated correctly, how would that affect the results of a measurement? The Resolution Equation in chromatography d...
