Name the four types of bonds carbon can form

Carbon can form single bonds (sharing of 2 electrons), double bonds (sharing of 4 electrons), and/or a triple bond (sharing of 6 electrons).

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.
