2H₂S(g)+3O₂(g)→2SO₂(g)+2H₂O(g) What mass of oxygen gas is consumed in a reaction that produces 4.60 mol SO₂ ?

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

answerspecific gravity;

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.
