What is the molar solubility of silver chromate? What is the solubility of silver chromate (in grams/L) in 0.045 M potassium chromate?
You have a balloon that is not permeable to gas molecules. The balloon is spherical and has a circumference of 3.141592654 m when it is filled with a gas at 20 EC and 1.0000 atm pressure.
Suppose that O1 and O2 are eigenfunctions of a linear operator A with eigenvalues a1 and a2, respectively, and that we construct a linear combination Y=C1O1 + C2O2
Ammonium Chloride and sodium hydroxide. Sodium cyanide and ammonium bromide. Potassium hydrogen sulfate and lithium acetate. Ammonia hypochlorite and ammonia
Water with an alkalinity of 2.00 X 10^-3 equivalents/L has a pH of 7.00. Calculate [CO2], [HCO3-], [CO3^2-], and [OH-].
a gas sample containing 1.50 mol at 25 exerts a pressure of 400 torr. some gas is added to the same container and the temperature increased to 50 C. If the pressure increases to 800. torr, how man moles of gas were added to the container? assume a..
Write the reaction with water that is the ionization of propionic acid to propionate, draw this out in two ways. First with expanded structures, of course, all atoms and all bonds.
Does caffeine or chlorophyll have a higher Rf value? Briefly explain why by discussing the intermolecular forces present in the molecules
A solution of salicylate dianion is prepared by mixing 0.158 g of reagent grade acetylsalicylic acid in 5 mL of 1 M sodium hydroxide and heating the mixture until all of the solid dissolves.
there is no measurable difference between final and initial pH - that is why it is called a buffer E. final pH is 0.16 pH units lower than original pH
The most probable mechanism of reactivity for the solvoysis of 2-chloro-norbornane is: a. Sn1 b. Sn2 c. E1 d. E2 The reaction for this secondary compound was very slow going compared to solvolysis of benzyl chloride
For the reaction CO(g) + H2O(g) CO2(g) + H2(g), Kp = 0.64 at 900 K. If the reaction is initiated with just H2(g) and CO2(g), each at a partial pressure of 0.540 atm, what is the partial pressure of CO(g) at equilibrium
the heat of combustion of c10h18 is -6286 kj/mol. the heat of combustion for c10h8 is -5157kj/mol.
