A twist of 0.03 radians on a shaft equal to the diameter of your car tire, with a G = 65 GPa on a length equal to your height in meters, will it produce a shear stress, τ? Show work.
8 ml of the HCl was used to titrate the pK_a 3.8 group; so 2 ml was enough to titrate the rest of the high pK_a group. The upper pK_a group must have begun the experiment as 80% acid form, 20% base form.
Nickel and aluminum electrodes are utilized to build a galvanic cell. State the standard reduction potential for the nickel (II) ion is -0.26V and that of the aluminum (III) ion is -1.66V. Type the shorthand notation for this cell. Do not include ..
Consider the following reaction at equilibrium. What effect will adding more H2S have on the system? 2H2S + 3O2 ---> 2H2O +2SO2
If the preference for formation of a six-membered ring was not so great, what other cyclic product would be formed from the intramolecular aldol addition of
Explain what volume of 0.200 M K2Cr2O7 will be required to oxidize the Fe2+ iron in 60.0mL of .200 M FeSO4 solution. Cr2(O2-)7 + Fe2+ -->Cr3+ + Fe3+
Assuming no energy is transferred to or from the surroundings, calculate the final temperature of the water after all the ice melts.
What can make the titrated solution at the equivalence point in an acid-base titration have a pH not equal to 7
Problem- A 2.50 mol quantity of NOCL was initially placed in a 1.50-L reaction chamber at 400 C. After equilibrium was established, it was found that 28.0 percent of the NOCL had dissociated: 2NOCL (g) 2NO (g) + Cl2 (g). Calculate the equilibriu..
Outline the phase diagram of the system nh3/n2h4 given that the two substances don't form a compound with each other, that nh3 freezes at -78 C and n2h4 freezes at +2 C and that a eutectic is formed while the mole fraction of n2h4 is 0.07 and that..

how many grams of ethylene glycol c2h4oh2 are needed per kilogram of water to protect radiator fluid against freezing
In BPTI the phenylalanine has five aromatic resonances of equal intensity. However after incubation in 6 M urea the same Phe has three resonances, one of which has half the integrated area of each of the others which have the same area.
