If 18.4 mL of 0.800 M HCl solution are needed to neutralize 5.00 rm mL of a household ammonia solution, what is the molar concentration of the ammonia?
Some compounds sublime in the capillary and some decompose before melting. How do you determine melting point of these compounds
When 1.00 moles of HI(g) is sealed in 1.00L flask at 225 degrees Celcius, it decomposes until the equilibrium amount of I2(g) is 0.182 moles. Calculate Keq using this information. The decomposition reaction is HI(g)=I2(g) +H2(g).

The solubility of benzoic acid in water is 6.80g per 100mL at 100 degrees Celcius. Calculate the minimum volume of water needed to dissolve 1.00g benzoic acid at 100o^C
100 mL of a 0.125 M solution of HBr was titrated with a 0.100 M solution of KOH at 25 C. The equivalence point will be reached after addition of what volume of the titrant?
A flask contains 0.330 mol of liquid bromine, Br2. Determine the number of bromine molecules present in the flask.
I'm trying to work a separation scheme for 50% ethyl 4-aminobenzoate, 40% benzoin, and 10% 1,4-dibromobenzene. I was going to start with distillation to extract the ethyl 4-aminobenzoate because it has the lowest boiling point. Is there a good sol..
