Calculate the number of moles in 3.00 × 108 L of 0.0400 mM CrO42–.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

explanation:

0.07 g/cm³

1.37 g/cm³

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
