How are casts formed by decaying organisms? organisms turn into rock over time. organisms leave carbon residue on a rock. organisms leave impressions in sediment that hardens into rock. impressions left by organisms are filled in with sediment that hardens into rock.

The amount of iron in ore can be quantitatively determined by titrating a solution of the unknown with a standard solution of dichromate, cr2o72−. the net ionic equation is 6fe2+(aq)+cr2o72−(aq)+14h+(aq)→6fe3+(aq)+2cr3+(aq)+7h2o(aq) part a the titration of 25.0 ml of an iron(ii) solution required 18.0 ml of a 0.230 m solution of dichromate to reach the equivalence point. what is the molarity of the iron(ii) solution?
