Lauren, a chemistry student, makes the following claim: My results showed that even more energy was lost during combustion during the food burning compared to burning pentanol. I think this is because the large flames and fast burning caused more energy to be lost to the surroundings. Also, I could see smoke during the combustion, showing that not all the fuel was burned. Does this match your results?

Which of the following is most likely true about water in chemical solutions?

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.

Witch two conditions can limit the usefulness of the kinetic molecular theory in describing gas behavior?
