An oxidation-reduction reaction happens when hydrogen, oxygen or halogen atoms are transferred, so in this case, your answer would be B.
Explanation:
oh shi sorry I wish I could help but I'm stupid
Yes. In a homogeneous mixture the hydrogen and oxygen are not chemically combined; in water vapor, they are. You can separate a homogeneous mixture of hydrogen and oxygen by physical means, such as by cooling the mixture until the oxygen liquefies. If you cool water vapor you're just going to get liquid water and then ice - not two separate substances. That's because compounds can only be separated into their elements by chemical means.
Answer: 2LiBr(aq) + F2(g) —> 2LiF + Br2
explanation: Br and F are both nonmetals. Nonmetals should only replace other nonmetals in a single replacement reaction.
The statement that best describes the effect of low ionization energies and low electronegativities on metallic bonding is the first one - the valence electrons are easily delocalized.
Due to these low energies and negativities, valence electrons can be moved around quite easily and their positions may be altered quite drastically.
