Let's write the reaction first:
<span>2 Au + 2 BrF</span>₃<span> + 2 KF → 2 KAuF</span>₄<span> + Br</span>₂<span>
</span>
To know which of the substances is the oxidizing agent, calculate the oxidation numbers of each element before and after the reaction. If the element's oxidation number decreases, then that is the oxidation agent. Let's calculate Br.
BrF₃: x + 3(-1) = 0; x = +3
Br₂: 0 (for any elemental form, oxidation number is 0)
The oxidation number is reduced from +3 to 0. <em>Thus, BrF₃ is the oxidizing agent.</em>
The type of central-atom orbital hybridization corresponds to each electron-group arrangement
Linear
What is linear arrangement?
Linear molecules are molecules that are straight and have a bond angle of 180 degrees. These molecules are made up of a central atom that is bonded to two other atoms via single or double bonds (sometimes there can be triple bonds as well).
Furthermore, the central atom usually can have either 0 or 3 lone electron pairs (AX2 or AX2E3) in the AXE notation.
The geometry described by linear molecular geometry revolves around a central atom that is bonded to two other atoms (or ligands) at a bond angle of 180°.
