Choose all that apply. when creating a graph, you should: determine the x- and y- variables label the scale on the x- and y- axes plot the data points draw a line of best fit to represent the data trend

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
