HELP! Why are intensive properties useful for identifying a substance? A. They are physical properties.

B. They are chemical properties.

C. They describe the amount of substance you have.

D. They do not depend on the amount of substance you have.

explanation: no but i do not usually comment

fe 55.85 g/mol and h2o 18.02 g/mol.

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.
