The compound that has the highest molecular weight based on the chromatogram is the compound with Rf 0.25.

A chromatogram is an output that shows the extent of separation of the components of a mixture. If the Rf is high, then it means that the substance traveled a large distance through the plate and vice versa.

Similarly, the molecular mass of the substances correlate with the Rf value observed for each component. The components with high molecular mass always show a low Rf value.

This implies that the lowest Rf value corresponds to the largest relative molecular mass. Thus, the compound that has the highest molecular weight based on the chromatogram is the compound with Rf 0.25.

Which of the following compounds would have the highest boiling point?
grin007 [14]

Answer:a. 1-propanol,

Explanation:

Boiling point depends on the relative molecular mass of the compound and the kind of intermolecular interactions present in the substance. 1-propanol has a relative molecular mass of 60 and posses strong intermolecular hydrogen bonding. The presence of hydrogen bonding is known to lead to an increase in boiling point. As a result of this, it is obvious that 1-propanol has the highest boiling point among other compounds in the list.

What is the wavelength of electromagnetic radiation with a frequency of 9.23 × 10^-7 Hz?
stich3 [128]

3.25 x 10¹⁴m

Explanation:

Given parameters:

Frequency of the radiation = 9.23 x 10⁻⁷hz

Unknown:

Wavelength of the radiation = ?

Solution:

The velocity of electromagnetic radiation is the same as that of the speed of light in vacuums.

  Velocity = frequency x wavelength.

 Velocity = 3  x 10⁸m/s

Since the unknown is wavelength, we factor it out:

    Wavelength = \frac{Velocity }{frequency}

    Wavelength = \frac{x}{y}\frac{ 3 x 10^{8} }{9.23 x 10^{-7} }

                          = 3.25 x 10¹⁴m
