Question- 1.Calculate the volume in mL of 14.8 M H2SO4(aq) solution required to prepare 250mL of a 2.5 M sulufric acid solution.
2. Calculate the mass (in g) of carbon dioxide produced by the combustion of 35.0g of propane (C3H8(g))____C3H8(g)+___O2(g) ---> ___CO2(g)+H2O(g)
3. Calculate the concentration (in molarity) of a solution prepared by dissolving 17.75g of solid KOH in enough water to make 500 mL of solution.
Explain the each step. Explain the process and each step.
A compound of forumula C14H12 gave a positive Baeyer test and burned with a yellow, sooty flame. Treatment with ozone followed by hydrolysis in the presence of zinc gave formaldehyde as one of the products.
how would the molarity be affected by the followingcircumstances i.e. would it be higher than the true value lowerthan
Suggest simple laboratory tests you could use to distinguish acetone, carbon tetrachloride, cyclohexane, ethyl ether and ethanol.
define what is the resulting total pressure of gases in the now-joined flasks. Presume no reaction between the gases and that the gases behave ideally
if 0.100 m NaCl is added slowly to a beaker containing both .120m AgNO3 and .150m Pb(NO3)2 at 25 celsius which will precipitate first AgCl or PbCl2?

why is it not necessary to precisely measure the amount of water added to the sodium chloride in the procedure
How long will it take 10.0 mL of oxygen gas to effuse through a porous barrier if it has been observed that 81.7 minutes are required for 10.0 mL of Cl2 gas to effuse through the same barrier?
would the separation of the grape soda dyes work equally well if you reversed the order of IPA concentrations and used 20% IPA first to remove the blue dye and then switched to 5% IPA to remove the red dye
A 100.0 mL sample of 0.300 M NaOH is mixed with a 100.0 mL sample of 0.300 M HNO3 in a coffee cup calorimeter. Both solutions were initially at 35.00°C and the temperature of the resulting solution was recorded as 37.00°C
