2CH4 + 2NH3 +3O2 Arrow 2HCN + 6H2O CH4 is going to be used up making it the limited reagent 13.5 g CH4 10gNH3(1 mole NH3)(2 mole HCN) (14.01g NH3)(2 mole NH3) =.714 mole HCN Do the same for Ammonia and you get .499 mole HCN or .50

It's a monomial and we are told to simplify and assume no denominator is equal to zero. its a -10m-1y0r means -10m to the neg. 1 power and y to the 0 power and r. I don't know how to write the powers. that equation is divided by -14m-7y-3r-4.which means -14m to the -7 ...

For the reaction H2(g) +S(s)->H2S(s), Triangle H= -20.2 kJ and triangle S= 43.1 J/K. WHen will the reaction be spontaneous? I know that it has to be negative to be spontaneous but i dont exactly know how to answer this question.

**chemistry**

is this true or false? i think its false because isnt it spontaneous if its positive When (triangle i think its called delta) H for a reaction is large and positive, the reaction is not expected to be spontaneous.
