If you make a mistake and deliver less than 50.00 mL of HCl to the Erlenmeyer flask, what effect will this have on the calculation for the acid-neutralizing ability of the antacid?
How many moles of ammonia are present originally? What is the theoretical yield of sodium bicarbonate in grams?
Given the stepwise formation constants for Zn(NH3)4 complex are logKf1=2.18 , logKf2=4.43 , logKf3=6.74 , logKf4=8.70 and the pKb fo ammonia is 4.76.
A 1.678 g sample of a component of the light petroleum distillate called naphtha is found to yield 5.143 g CO2 (g) and 2.456 g H2O (l) on complete combustion. This particular compound is also found to be an alkane with one methyl group attached to..
Oxalic acid dehydrate, H2C2O4. 2H2O (formula weight = 126.1 g/mol) is sometimes used to standardize NaOH solutions. How many grams of this acid will be required to titrate 45.0 mL of 0.18 M NaOH solution
Acid-base titration & analytical chemistry, A 0.213-g sample of uranyl(VI)nitrate, UO2(NO3)2, is dissolved in 20.0 mL of 1.0 M H2SO4 and shaken with Zn. The zinc reduces the uranyl ion, UO2 (with a charge of 2+)
The molar heat of vaporization of carbon disulfide, CS2, is 28.4 kJ mol-1 at its boiling point. How many kilojoules of heat would be liberated by the condensation of 9.75 g of carbon disulfide?
