Write the equations that represent the first and second ionization steps for selenic acid (H2SEO4) in water.
When given a problem with an aqueous solution containing Na3PO4 and you need to find the boiling point of the solution only knowing the solution is 18.7% by mass Na3PO4 and the Kb for water is .512 It also says to consider if the solute is an elec..
The total amount of water runoff from the road is equal to a volume that would make the water on the roadway be at a depth of 0.4 inches if it all stayed on the roadway.
a buffer composed of .250 mol H2PO4- and .250 mol HPO4^2- diluted with water to a volume of 1.00L. the pH of the buffer is 7.210 how many moles of HCl must be added to decrease the pH to 6.700
When we looked at assigning the electrons in nitrogen to sites in the 2s and 2p orbitals, we used the 2s anti-bonding site. Which statement about this site is not true?
A technician was accidentally exposed to potassium-42 while doing some brain scans for possible tumors. the error was not discovered until 48h later when the activity of the potassium-42 sample was 2.1?ci .if potassium-42 has a half-life of 12 h
Calculate the minimum pH difference between the stroma and lumen, so that three protons passing through an ATP synthase would provide enough energy for the generation of one ATP molecule
Calculate the pH of a buffer that contains 0.270 M hydrofluoric acid (HF) and 0.180 M cesium fluoride (CsF). The Ka of hydrofluoric acid is 6.80 x 10^-4.
What minimum voltage is required to electrolyze anhydrous HF? Hint: the H-F bond is so polar that liquid HF is essentially composed of H+ and F- ions.
An apparatus to be used in a decomposition study was filled with N2 gas at 400.00 mm Hg and 400.0 deg C. The volume of the apparatus was 400.0 mL.
Suppose 8.26 g of solid Mg(OH)2 is added to 36.1 mL of 0.488 M H2SO4 solution. What will the concentration of Mg2+ be when all of the acid has been neutralized. How many grams of Mg(OH)2 will not have dissolved.
what polymer is made from the monomer vinylidene chloride
Water expands on freezing. Since water is the principle ingredient in soft drinks when the soft drink freezes it will rupture the can.
