(1) two baking sheets are made of different metals. you purchase both and bake a dozen cookies on each sheet at the same time in your oven. you observe that after 9 minutes, the cookies on one sheet are slightly burned on the bottom, whereas those on the other sheet are fine. (you are curious and you vary the conditions so you know the result is not caused by the oven.) (a) how can you use this observation to infer something about the specific heat of the materials in the baking sheets? (b) what is the mathematical reasoning (equation) that you need to support your conclusion?
Given that the reaction N2(g) + 2 O2(g) → 2 NO2(g) is endothermic, what is true of the reaction 2 NO2(g) → 2 N2(g) + 2 O2(g) ?
