Suppose a new metallic element x is discovered, and its reactions with oxygen gas and chlorine gas at 298 k are studied. trial reaction δhºrxn (kj/mol) 1 4x(s) 3o2(g) → 2x2o3(s) –600 2 2x(s) 3cl2(g) → 2xcl3(s) –800 3 4xcl3(s) 3o2(g) → 2x2o3(s) 6cl2(g) –200 however, it is later discovered that one of the samples was contaminated, and the δhºrxn value from this trial is not reliable. which trial had the contaminated sample, and what should the correct value of δhºrxn be for this trial
