The reaction described by h2(g)+i2(g)⟶2hi(g) has an experimentally determined rate law of rate= some proposed mechanisms for this reaction are: mechanism a (1) h2(g)+i2(g)−→(g) (one-step reaction) mechanism b (1) i2(g)⥫⥬=−(g) (fast, equilibrium) (2) h2(g)+2i(g)−→(g) (slow) mechanism c (1) i2(g)⥫⥬=−(g) (fast, equilibrium) (2) i(g)+h2(g)−→(g)+h(g) (slow) (3) h(g)+i(g)−→(g) (fast) which of these mechanisms are consistent with the observed rate law?

If 90.0 grams of ethane reacted with excess chlorine, how many grams of dicarbon hexachloride would form

What information does a complete ionic equation give that the balanced equation doesn’t show?

Tooth enamel consists mainly of the mineral calcium hydroxyapatite, ca_10(po_4)_6(oh)_2. trace elements in teeth of archaeological specimens provide anthropologist with clues about diet and diseases of ancient people. students at hamline university measured strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. solutions with a constant total volume of 10.0 ml contained 0.726 mg of dissolved tooth enamel plus variable concentrations of added sr. added sr find the concentration of sr in the 10 ml sample solution in parts per billion = ng/ml. find the concentration of sr in tooth enamel in parts per million = mu g/g.
