Consider a single crystal oriented such that the slip direction and normal to the slip plane are at angles 42.7° and 48.3°, respectively, with the tensile axis. If the critical resolved shear stress is 26.2 MPa, what applied stress (in MPa) will be necessary to cause the single crystal to yield?
predict the products of each precipitation reaction. Balance the completed equation, and then write the net ionic equation. please show steps.
Cesium-131 is a short lived radioisotope (t1/2= 9.7 days) used to treat prostate cancer. How much theraputic strength does a Cesium-131 source lose over 60 days? Express your answer as a percent of the strength the source had at the begining of th..

The pH of an aqueous solution is 6.17 at 25 degree C. Calculate the Ka for the acid. The initial acid concentration is 0.011M.
if 0.200mole of NaOH is added to 1 liter of solution that is 0.100M in aqueous ammonia and 0.200M in ammonium chloride how much does the Ph change.
How does the answer for part (a) change if the gas of interest is He? c) What is the largest molecular mass that is capable of escaping Earth's surface at 298 K?
In solving weak acid equilibrium problems to find [H+] or pH, a major assumption is usually made. This major assumption can be represented by the following
he maximum contaminant level (MCL) for barium (Ba) in drinking water is 2.0 mg/L. Barium can combine with sulfate (SO42-) to form BaSO4(s), which precipitates out of the water. This can be achieved by adding Na2SO4
A 0.5078g sample of impure nitrobenzene was treated with 1.044g of tin. when the reaction was complete, the residual tin was found to weight 0.338g. Calculate the percentage of nitrobenzene in the sample.
The colors of the acid and base forms of the indicator bromocresol green are yellow and blue, respectively, and its pKa is 4.6. What color would be expected for the indicator in a solution of pH 6.0 and in a solution of pH 4.8?
A 1.6-m-long string fixed at both ends vibrates at resonant frequencies of 708 Hz and 1062 Hz, with no other resonant frequency between these values.
A flask containing 450 mL of 0.47 M H2SO4 was accidentally knocked to the floor. How many grams of NaHCO3 do you need to put on the spill to neutralize the acid according to the following equation?
