<em>Follow sig fig rules and round. We are given 4 sig figs.</em>
1.49672 mol Ir ≈ 1.497 mol Ir
Polar Covalent ; the result is a bond where the electron pair is displaced toward the more electronegative atom. This atom then obtains a partial-negative charge while the less electronegative atom has a partial-positive charge.This separation of charge or <span>bond dipole.

The dipoles create dipole dipole interactions which are inter-molecular interactions and thus effects the reactions it takes place.
Also Polar dissolve in water and Non Polar don't.

Put simply, a covalent bond is a chemical bond between two atoms where electron pairs are shared.
Answer:
A
Explanation:
A chemical change happens when one chemical substance is transformed into one or more different things , such as when iron becomes rust so
B: Acids turn the indicator red, pink, orange, and yellow, while bases turn it green based on what it reactions with or comes in contact with so b is maybe
c is wrong
and d a physical change, will technically yes and no there should have not been a smell afterwards so the only really choose that makes sense here is A
