briefly summarize what determines the maximum number of covalent bonds that can be formed by elements in period 2. why can elements in period 3 violate this rule

i dont know the answe

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.
