Question

PLEASE HELP! I'M NOT THAT GOOD AT CHEMISTRY AND I REALLY NEED TO PAST THIS.
1. You have three elements, A, B, and C, with the following electronegativity values:
A = 0.9
B = 3.0
C = 3.5
You react the elements to form the substances AB, AC, and BC. Answer the following questions:
• What type of substance is AB? What types of bonds are present? Explain your answer.
• What type of substance is AC? What types of bonds are present? Explain your answer.
• What type of substance is BC? What types of bonds are present? Explain your answer.
• If any of the substances are ionic compounds,

Answer 1

which element is the cation and which is the anion? Explain your answer.

Answer 2

@Whitemonsterbunny17 Can you help me please?

Answer 3

AB is most likely a covalent and polar substance, because it contains polar covalent bonds. (The difference in electronegativity, 1.1 (3.0-.9), is in the range for polar covalent bonds).

I think the range is about .4 to 1.7, with less than .4 being non-polar covalent and greater than 1.7 being ionic. Keep in mind that geometry affects polarity.

So with the other questions, consider the difference in electronegativity between the 2 bonded substances and where that falls in the range.
