A chemist studying the properties of photo- graphic emulsions needed to prepare 500 mL of 0.18 M AgNO3 (aq). What mass of silver nitrate must be placed into a 500 mL volumetric ?ask, dissolved, and diluted to the mark with water? Answer in units of g.
I dissolved .5 grams of mustard in 3 mL of distilled water. I was asked to determine the mass percentage of acetic acid in mustard, so I added 2.5 mL of NaOH to turn the mustard solution red.
Suppose that you developed your own new temperature scale, denoted oN. You chose 30.0oN as the temperature of freezing water and 280oN as the temperature of boiling water at 1.0 atm pressure.
Given equilibrium pressure, calculate Kp, When heated, ammonium carbonate decomposes as follows. NH4CO2NH2(s) f/r2NH3(g)+CO2(g)
How many grams of CaCl2 would be required to produce a 3.5 M (molar) solution with a volume of 2.0 L.
A patient needs 0.004g of a sulfa drug. There are 5.00mg tablets in stock. How many tablets should be given.
5.0 g of H2O at 23.0 oC is added to 100.0 g of H2O at 67.5 oC. What is the temperature of the resulting mixture
Compute the final pressure in the tank if nothing else is altered in the surroundings. (The two gases do not react)
Using K=3.9 as the equilibrium constant, Keq, Compute the amount of Isoamyl acetate, also known as isopentyl acetate (C7H14O2 )that must be present at equilibrium.
When CO2 is bubbled through an ether solution of benzylmagnesium bromide, and the resulting mixture is acidified, phenylacetic acid is produced.
A 0.4647-g sample of a compound known to contain only carbon, hydrogen, and oxygen was burned in oxygen to yield 0.8635 g of CO2 and 0.1767 g of H2O.
Could you explain why carbonate, specifically sodium carbonate (Na2CO3) would be particularly good at neutralizing these acids and their conjugate bases?
What volume of 0.200M Hydrochloric acid must combined to 250mL of 0.300M C8H7NaO3 to produce a buffer of solution with a pH of 3.37?
