Hydrolamine ,NH2OH , is a reducing agent found in some film developing solutions. How many hydrogen atoms are in 1.80moles of hy
kolezko [41]

Answer:

number of hydrogen atom in 1.8 mole of NH2OH = 9.8\times 10^{22}

Explanation:

percentage of hydrogen in NH2OH = mass of hydrogen / mass of whole molecule

                                                             =\frac{3\times 1}{14+3+16}\times 100

                                                             = 9.09 percentage

therefore number of moles in 1.8 moles of hydroxy amine = \frac{9.09}{100}\times 1.8

                                                                = .16 moles of hydrogen

number of hydrogen atom = (number of moles )×(avagadro number)

                                              = 9.8\times 10^{22} atoms of hydrogen

What does the rf value describe on a microscopic level why is this important?
lys-0071 [83]

Answer: The retention factor describes the rate at which a compound migrates on a microscopic level.

The retention factor (Value) serves as a simple measurement of the relative binding of the compound of interest under the experimental conditions.

Retention factor values are used in identification purposes;

• Use to determine the affinity of the solute to the solvent

• Greater retention factor means greater affinity of solute to the solvent
