Answer : Maggie can change the question "How can recycling the plastic lower its exposure effect on environment" which will also include the scientific question on recycling procedures for plastics and what will be the effect of it on environment compared to normal plastics.

The environmental effects can be studied and related with the recyclable plastics and will promote the usage of such plastics.

Predict whether each of the following molecules is polar or non-polar:a) IF,b) CS2, c) SO3, d) PCl3, e) SF6, f) IF5.
BlackZzzverrR [31]
<h3><u>Answer;</u></h3>

Polar: IF, PCl3, IF5  

Nonpolar: CS2, SO3, SF6

<h3><u>Explanation:</u></h3>
  • Polar molecules form when two atoms do not share electrons equally in a covalent bond.
  • A molecule is classified as a polar molecule when the arrangement of the atoms is such that one end of the molecule has a positive electrical charge and the other end has a negative charge.
  • A non-polar molecule does not have electrical poles.The electrons are distributed more equally.
  • Therefore, a non-polar molecule does not have a profusion of charges at the opposite ends. The majority of hydrocarbon liquids are non-polar molecules.
