For the reaction CH4(g) + 2H2S(g) ↔ CS2(g) + 4H2(g), after disrupting equilibrium the initial values for each gas were 1.24M CH4, 1.52M H2S, 0.285M CS2, and 0.233M H2. The original value for Kc was 0.00012, which means what about Q?

Which statement about hf is true? it is zero for any compound in its standard state. it is positive when the bonds of the product store more energy than those of the reactants. it is negative when a compound forms from elements in their standard states. it is zero for any element that is in the liquid state.
