2H2S(g)<---> 2H2(g) + S2(g) The value of Kc for the thermal decomposition of hydrogen sulfide is 2.2x10^-4 at 1400 K. A sample of gas which [H2S]=3.65 M is heated to 1400 K in a sealed vessel. After chemical equilibrium has been achieved, what is the value of [H2S] in M? Assume no H2 or S2 was present in the original sample.

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt
