Calculate the pH resulting from mixing 15.00 mL of 0.800 M HIO3 (pKa = 0.77) with 45.00 mL of 0.0200 M NaOH.
What are the structures of the products that would be expected to be obtained on hydration of 1-octyne and 2-octyne?
Consider the four equations of states(EOS) below describing PVT behavior of gases. Let a and b be constants. EOSI : PV = RT EOSII: (P-a)V = RT EOSIII: P(V-b) = RT EOSIV: P = RT/(V-b) - a/V (a) Prove for EOSI that both U and H are functions of T on..
Assuming the mixture has the same specific heat (4.184J/goC) and density (1.00 g/cm3) as water, calculate the heat (in J) transferred to the surroundings, qsurr.
What volume of gold would be equal in mass to a piece of copper with a volume of 140.0 mL? The density of gold is 19.3g/mL; the density of copper is 8.96 g/mL.
The labeling of acetone with 18O is catalyzed by both acid and base. Show Mechanisms for both reactions.
What is the change in internal energy (in J) of a system that releases 675 J of thermal energy to its surroundings and has 7.60x10^2 cal of work done on it
Calculate the molar solubility of Fe(OH)2 in a buffer solution where the pH has been fixed at the indicated values. Ksp = 7.9 x 10-16. When pH is 7.8
what is the change in internal energy of a system that absorbs 0.570 kj of heat from its surrounding and has 0.843 kcal of work done on it give in scientific notation
how many grams of KOH are present in 32.5mL of a 6.42 M KOH solution
M. tuberculosis, the organism that causes tuberculosis, can be completely destoryed by irradiation with UV light with a wavelength of 254 nm. What is the frequency?
If the reaction mixture initially contains only O2(g) and F2(g), then at equilibrium, the reaction mixture will consist of essentially only OF2(g).
At this temperature, calculate the number of moles of NO2(g) that must be added to 2.76 mol of SO2(g) in order to form 1.20 mol of SO3(g) at equilibrium.
