A sample of water is to be analyzed for solids content. Ten liters (10 L) of water are passed through a filter initially weighing 15 g. After drying at 105oC, the filter plus residual weighs 43 g. The filter is heated to 550oC, and the filter plus
The system is under both mechanical and thermal equilibrium. Calculate the entropy and Gibbs energy of mixing when the patrition is removed, Assume that the gases are perfect.
When light of frequency 5.26×1015 s-1 shines on the surface of a metal, electrons are ejected with a maximum kinetic energy of 2.68×10-19 J.
By how much must the iron unit cell expand to accommodate carbon? That is, what is the increase in the unit cell length.
Chromium (iii) hydroxide Cr(OH)3 is highly insoluble in distilled water but dissolves readily in either acidic or basic solution. Briefly explain why the compound can dissolve in acidic or in basic but not neutral solution.
Draw a schematic showing several neighboring lattice unit cells and indicate the slip systems (slip plane(s) and slip direction(s)) which are activated by this type of loading. How many independent slip systems are active?
A partially filled closed tank contains ethyl alcohol at 68 degrees F. If the air above the alcohol is evacuated, what is the minimum absolute pressure that develops in the evacuated space?
The following reaction has an equilibrium constant of K =1.6x10-21 at 298 K. The equilibrium constant increases to K = 10.0at 1100 K. Given this information and the following reaction, what does this tell you about the change of enthalpy, ΔH
If the annual production of acetyl salicylic acid in the U.S.A. were converted to 5-grain aspirin tablets, approximately how many tablets would there be for each person?
Calculate the change in entropy if 24.7 g of water at 78.4°F is mixed with 15.3 g of alcohol at 106°F. (The specific heat of water at constant presure is 4186 J/kg·K and that of alcohol is 2305 J/kg·K.)
