A pigment solution contains compound A with 4 polar groups and compound B with 2 polar groups. You plan to separate these compou
Karolina [17]

The more polar A compound moves ahead of the less polar B compound.

Explanation:

The analytical process that involves the separation of colored substance or chemicals is named as paper chromatography, a replacement of thin-layer chromatography. In this method, there is the use of two solvents and rotation of paper at 90^0. It helps in isolating two complex compounds of equal polarity.

A non-polar mixture of solvent is required in the mobile phase of this method. In accordance with the retention factor of this process, the more polar compound A will go further than compound B as the solvent is non-polar.

One problem with wind energy as a major source of electricity is _____. A. it is nonrenewable B. it causes major air pollution C
irina [24]

The correct option is D.

Wind has some advantages which makes it suitable as a source of energy but it also possesses some disadvantages which reduces its potentials as a viable source of energy. For instance, large expanse of land will be needed to construct wind farms and this may not be feasible especially in populated areas. Another disadvantage is that electricity production will be depended on the availability of wind, when there is no wind, there will be no electricity.

What is molecular polarity
krek1111 [17]

Answer:

The electron density of a polar bond accumulates towards one end of the bond, causing that end to carry a slight negative charge and the other end a slight positive charge. Likewise molecules in which there is an accumulation of electron density at one end of the molecule, giving that end a partial negative charge and the other a partial positive charge, are called polar molecules.
