From your Δ H soln and the tabulated Δ H f 0, determine Δ H f 0 for the cation in the salts. Natural, Vegan, and Organic ingredients. We ran out and he asked me to buy him some more. It looks and acts much like ice, but it contains huge amounts of methane; it is known to occur on every continent; and it exists in huge quantities in marine sediments in a layer several hundred meters thick directly below the sea floor and in association with permafrost in the Arctic.
