A person receives 50 mrad of gamma radiation. Explain what is that amount in grays? Define what would be the equivalents does in millirems?
Bronze is an alloy consisting of 88.0% copper and 12.0% tin. The density of copper is 9.28 g/mL and the density of tin is 7.48 g/mL. Calculate the approximate density of bronze.
Benzene is a organic solvent with the formula C6H6. it boils at 80.1 degrees celcius and melts at 5.5 degrees celsius. benzene's density is 0.88gm/ml, its heat of fusuion is 10.0 KJoules per mole.

The following isotopic cluster was observed in a mass-spectrum of a parent peak of a halogenated compound:
For an electron in a hydrogen atom, compute the most likely radius (in Angstroms) of the electron in each of the following states:
If a single pill contains 0.150 grams of KCN How much HCl in grams would be necessary to consume all of the KCN
the kp value was calculated as 8.491 g. what does the kp value tell you about the solubility of benzoic in the two
In a chemical reaction (unbalanced equation), AsF3 + C2Cl6 = AsCl3 + C2Cl2F4, the theoretical yield of C2Cl2F4 was calculated to be 1.86 mol. If the percent yield in the reaction was 77.2%.
The volume of the base required to neutralize the acid was 47.14 mL. Aqueous silver nitrate was then added to precipitate the Cl- and Br- ions as AgCl and AgBr. The mass of silver halides obtained was 0.9974 g. What are the molarities of HCl and H..
