When a rock has low porosity, what does this mean?
1. It is so soft 2. Low volume of pores

b) mutualism

hope this : )

you gotta add the following molecules so we can give u an answer

explanation:

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.
