What Is 25 Closest To 30 Or 20?
It is equally close to both. If you are expected to round, the usual convention is to round up (to 30) in such cases - although sometimes other rules are used as well.It is equally close to both.

What tool used when measuring diameter of a round bar?
caliper. Micrometer
What is the difference between round and around?
Round is circular. Around means ' in the vicinity of'. Or used as an estimate Examples : The ball is round. That boy is always hanging around my sister. The bill for the meal will be around £25.
Does 50 round to 100 or 0?
That depends on the rounding rules used.
Estimate each sum or difference. identify the method you used. 312 - 287.6?
First you round 312 to 310 and then you round 287.6 to 290, which equals, 20. ;)
Why are cuvettes that are used in the 200-400nm range made of silica?
A cuvette is a very small tube that is sealed at one end and made of plastic, glass, or fused quartz. The reason why the cuvettes that are used in the 200-400 nm range are made of silica is because of the shifts in the chemical equilibria.
Identify function of each of the cuvettes?
hff
Why do you use quartz cuvette rather than using glass cuvettes?
Glass will absorb radiation below 320nm whereas quartz will allow transmission of the UV wavelengths. So use glass cuvettes for wavelengths in the visible range from 380nm to 780nm and quartz cuvettes for wavelengths below 380nm.
How is your blank cuvette different from your other cuvettes?
It is your control. Your baseline reading.
What are the precautions to be taken while using UV spectrophotometer?
One should not touch the optical assembly with bear hands. Optical surface of cuvettes should not be touched with fingers to avoid erratic reading. Always ensure effectiveness of silica gel kept in instrument. Preserve the instrument from dust particles. Never wash the cuvettes with chromic acid. Wash the cuvette with the distilled water and then with methanol before storage. Check the calibration status before using the instrument and ensure the timely calibration. Do not overfill the cuvettes. Perform the visual inspection of cuvettes for suitability.
What is the molar absorptivity of Cu2 plus at 620 nm given that the cuvettes used in lab had a pathlength of 1.00 cm with a concentration verse absorbtivity curve of y equals .727x plus .0557?
.727/g*M, slope is molar absorbtivity
What is a cuvette and how is it used?
A cuvette is, basically, a glorified test tube for use in a spectrometer. They're sometimes square in cross section to avoid refraction artifacts. Depending on what part of the spectrum is under consideration, they may be made of quartz, though plastic and glass cuvettes do exist. You put a liquid sample into it then put the cuvette into the instrument. The beams inside of the instrument can 'see through' the quartz and 'read' your sample.
What term is used to describe a pearl that is not round?
"Baroque" is a pearl that is not round.
What part of speech is the word round in the sentence circles are round?
"round" is used to describe the "circle". "circles" is the noun and "round" is an adjective.
What is a round object often used in games that rhymes with scrawl?
scrawl rhymes with "ball" which is a round object used in games!

What is the use of half- round file?
Half Round Files are used to smoothen rough edges after cutting or sawing woods, metals, plastics, etc. They are also used for shaping and curving materials into desired form or shape.
