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>
Answer: Allows scientists to avoid the effects of light pollution
Just took the quiz on edge.
Answer:
It could be some type of gas.
Type of intermolecular forces are expected between 3-bromopyridine molecules dipole induced dipole force.
Intermolecular pressure is the pressure among molecules it includes the forces of appeal and repulsion. however the intermolecular forces are weaker than intramolecular pressure, has London dispersion pressure.
Dipole precipitated Dipole Forces A dipole-brought on dipole enchantment is a weak enchantment that results while a polar molecule induces a dipole in an atom or in a non polar molecule by traumatic the arrangement of electrons inside the non polar species.
It is a dipole as the hydrogens have a partial superb fee and the oxygen has a partial negative charge. An precipitated dipole is the end result of molecules interacting and causing one of the molecules electrons to have this distorted rate.

Answer:
The volume is 77 L.
Explanation:
where P is pressure, V is volume, n is moles, R is the gas constant, and T is temperature in Kelvins.
The current STP temperature is 0∘C or 273.15 K (used for gas laws), and the pressure is 105Pa, which most people write as 100 kPa (both pressures are equal).
