What is the horizantal line test and vertical line test?
Horizonatal line test is a test use to determine if a function is one-to-one. If a horizontal line intersects a function's graph more than once, then the function is not one-to-one. A one-to-one function is a function where every element of the range correspons to exactly one element of the domain. Vertical line test is a test used to determine if a function is a function or relation. If you can put a vertical line through graph and it only hits the graph once, then it is a function. If it hits more than once, then it is a relation.
If a function is positive at a test number does the function has no zeros?
false!
What is the relationship between chest circumference and lung function test?
what is the relationship between chest circumference and lung function test
How do you use the vetical line test to determine a function?
f(x) = x2 This is a function by the vertical line test because a vertical line drawn through this function will only intersect the function at one point
When is it not a function?
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
Why resorcinol is used as a reagent in test in seliwanoff test?
Resorcinol is used as the complexing agent to provide the color reaction, although the exact nature of the colored product is not known. Since resorcinol favors electrophilic aromatic substitution, the reaction may be similar to the Molisch Test.
Why is resorcinol used to test honey?
Resorcinol is used to test honey to see if sugar has been added to the honey. After adding the solution of resorcinol to the honey boil it, if the mixture turns red it means sugar is added and the honey is not pure.
Why is it necessary to spray the chromatogram with resorcinol?
Resorcinol is a colouring agent for some chromatography experiments.
What is C6H6O2?
Resorcinol
Why does resorcinol give a false positive with the Duquenois Levine test?
the D-L test is based on the presence of 1,3-dioxybenzene partial structure. Any substance that contains this partial structure will test positive.
Principle in seliwanoff's test?
dehydrated ketones react with resorcinol to give a deep cheery red colour and aldose react to give a faint pink colour.
Chemical name of resorcinol?
1,3-dihydroxybenzene
What is more acidic catechol or resorcinol?
catechol
What is the IUPAC name of resorcinol?
meta Dihydroxybenzene
Why resorcinol is soluble in water?
Resorcinol is 1,3-dihydroxy benzene, it is acidic and two 'OH' groups make the system sufficiently polar so it is soluble in polar solvent water.
Is resorcinol soluble in water?
Resorcinol is 1,3-dihydroxy benzene, it is acidic and two 'OH' groups make the system sufficiently polar so it is soluble in polar solvent water.
Is Resorcinol polar or non-polar?
I believe so.
