No, the equation is: HPO4-2 → H+ + PO4-3
The HPO4-2 and PO4-3 are conjugate acid base pairs.
Rate = k[A]m[B]n
The buffer is in used is called as pinned buffer
Reactions that increase the moles of gas will increase in entropy.
the system has become more random
The pH is 5,6.
You think probable to an endothermic chemical reaction.
grams liquid x mol/g x H fusion
We can't answer because we don't know the statements you were given.
Air
(Explanation): water has a high specific heat capacity, but it can boil. stone (😂) also is a good thermal insulator, but it can get really hot. Metal is a very good thermal conductor, so it is definitely not that. Therefore, air is the best (its also really hard to boil).
