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.

Calculate the mass (in grams) of 8.56 moles of sulfur.
oksano4ka [1.4K]

Answer:

275g

Explanation:

Depending on the molar mass you are given, you can use that to solve this.

(I'm going based on my science class' molar mass of sulphur being 32.07g/mol)

Starting off, the formula for finding moles is

n=m/M (moles = mass / molar mass)

We can manipulate this equation to solve for mass.

m=Mn

now fill in what we now.

m = 32.07*8.56

mass = 274.5192

Now round for significant digits (if you are needed to do)

mass = 275g
