Asubstance is found to be reactive, flammable, soluble, and explosive. which of these observations is a physical property? a. reactive b. explosive c. soluble d. flammable

C. Soluble

Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.

the answer is c soluble

h let me think

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.
