Jose found four turtle eggs sitting in the grass in his backyard. He plans to take them to a nature center near his house where a scientist will help them. Jose needs to design a closed container to transport them to the nature center. Two important criteria are that the eggs must be kept warm—at a temperature between 27–32 degrees Celsius (C), and the eggs must be protected so the shells do not break. Jose wants to put a packet around the eggs that meet both criteria. He sets up three different possible combinations of water, calcium chloride, and baking soda in three different sandwich bags. Each bag represents a possible design for a packet. All three bags sit for the same amount of time. The table below shows his observations. (See pic below before the question) Which design should Jose choose for his packet? Why? a. Bag 1—energy was released in the form of a liquid, which will help protect the eggs.
b. Bag 2— energy was released in the form of gas, which will help protect the eggs.
c. Bag 3—energy was absorbed in the form of a solid, which will help protect the eggs.
d. None of the bags keep the eggs warm or provide protection.

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.
