Which component has Rf value of 1?
Blue.
What are largest and smallest Rf values?
The largest Rf value is 1, which occurs when the compound remains at the origin of the chromatogram and does not move at all. The smallest Rf value is 0, which happens when the compound moves with the solvent front and does not adhere to the stationary phase.
Which is more 1 yard or 2 inches?
To answer this question both values have to be converted to the same unit and compared afterwards. Let's convert both to inches: 1 yard = 36 inches After comparing we can see that value of 36 inches is more than value of 2 inches that makes value of 1 yard more than value of 2 inches.
What is the value of 251?
It is exactly 251: 1 more than 250 and one fewer than 252.
What is the place value of 62?
Only a single digit can have a place value, a number with more than 1 digits cannot .
Why are Rf values always less than 1?
Rf values are distance of substance from origin divided by distance of solvent front from origin. As the substance travels with the solvent, the solvent will always have a greater or equal value to the distance travelled by substance. This means the highest value of Rf is 1.
Is it possible to have a Rf value greater than 1?
No, it's not possible to have an RF value greater than one. Rf values are a ratio of the distance a spot has traveled to the total distance of the solvent front. Since the distance of the front is always greater than the distance of a spot, the Rf value is always less than 1.
What is the maximum and RF value can be?
1, if it completely solube in the solvent, it will travel with it, right to the solvent front.
Which component has Rf value of 1?
Blue.
Why does carotene have the highest Rf value?
The Rf value of the xanthophyll is two thirds that of carotene because xanthophyll has an H bond with cellulose, which slows it down, and makes it less soluble in the solvent. Carotene is more soluble in 9:1 petroleum-ether acetone solution, which caused it to be carried higher and have a larger Rf value.
What does it mean when the Rf value is less then 0?
When the Rf value is zero, it generally refers to the position of the substance in the chromatogram. This means it did not move of that origin point.
What does it mean if the Rf value is 1?
It means that the component will move with the solvent.
Why you used inverting op amp more than non inverting op amp?
since gain is simply -Rf/Ri and is 1+Rf/Ri in case of non inverting
How do you solve the Rf value in Column Chromatography?
Measure the distance from your marked pencil line to the solvent front. Also measure the distance fomr the marked pencil line to the middle of the spot, and divide this by the first distance. This value will be between 0 and 1.
What are largest and smallest Rf values?
The largest Rf value is 1, which occurs when the compound remains at the origin of the chromatogram and does not move at all. The smallest Rf value is 0, which happens when the compound moves with the solvent front and does not adhere to the stationary phase.
What is the Curreny of Maldives?
Hello The currency of Maldives is Rufiyaa. (1$ = 12.7500041 Rf) (1 Euro = 16.3846 Rf) (1 GBP = 20.0294 Rf)
What if you have a rheumatoid factor of 8?
Less than 40-60 u/mLLess than 1:80 (1 to 80) titerA low number (normal result) usually means you do not have rheumatoid arthritis or Sjogren syndrome. However, some people who do have these conditions still have a "normal" or low rheumatoid factor (RF).Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
