Standard Addition Graph: Tooth enamel consists mainly of themineral calcium hydroxyapatite. Trace element in teeth ofarchaeological specimens provide anthropologists with cules aboutdiet and disease of ancient people. Students at HamlineUniversity measure strontium in enamel from extracted wisdom teethby AAS. Solutions with a constant total volume of 10.0 mLcontained .750 mg of dissolved tooth enamel plus variableconcentrations of added Sr. A.) Find the concentration of Sr and its uncertainty in the 10-mL sample solution in parts per billion ng/mL. (b) Find the concentration of Sr in tooth enamel in parts per million g/g
draw correlation diagram the HOMO of allyl anion and the LUMO of ethylene and comment on the symmetry match of the two.
Fluorine-18, which has a half-life of 110 min, is used in PET scans. (see section 4.5.) If 100 mg of fluorine-18 is shipped at 8 A.M., how many milligrams of the radioisotope are still active if the sample arrives at the radiology laboratory at 1:..
Using a band diagram, explain how magnesium can exhibit metallic behavior when its 3s band is completely full.
How many moles of CO2 will be produced in the combustion reaction starting with the 15.02 grams of ethane.
A swimming pool measures 25 meters wide by 145 meters long by 1 meters deep. How many gallons of water are required to fill the pool?
Looking at the table of first ionization energy, if the n=1 shell held 3 electrons max instead of 2, then the first ionization energy for Li(g) would be around _____ MJ/mol.
Blood alcohol content (BAC) is often reported in weight-volume percent (w/v%). For example, a BAC of 0.08% corresponds to 0.08 g CH3CH2OH per 100 mL of blood. In Ontario, and the rest of Canada, the maximum legal BAC for fully licensed drivers is ..
Carbonyl fluoride, , is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, via the reaction
Draw the structure of propanoic acid (propionic acid) with the approiate hydrogen bonded water molecules -- that is, put in the maximum number of water molecules that could H bond with propionic acid. Remember -- H bonds (hydrogen bonds) are indic..
When the reaction is conducted in this way, however, a polymeric product is produced after step 1. What is the structure of the polymer? Why does p-acetamidobenzenesulfonyl chloride not produce a polymer
Calculate the theoretical ph of one of your buffer at 0^0 C. Assume that room temperature is 22^0 C. If none of your buffer is listed on the table of changing pka with temperature, do this problem for TRIS at ph 8.0.
