While 14 g of baking soda (NaHCO3) is added to 550.0 mL of vinegar an aqueous solution of CH3COOH at 5% concentration by mass, the vinegar neutralizes the baking soda as well as converts it to CO2 gas, which bubbles out of the solution. Find out the limiting reagent in this reaction and compute the mass of CO2 produced.
Determine the pH of the equivalence point for a reaction in which 0.100 mol/L NaOH(aq) neutralizes 10.0 mL of 0.250 mol/L HF(aq)
consider a 0.0500m HClO2 is a moderately weak electrolyte acid such that 36% of the molecules dissociate when dissolved in water. calculate the van't hoff factor
Suppose a sample of solid hydrogen is held under an external pressure of 0.030 atm and heated from 5 to 300 K. What phase change(s), if any, will occur?
if acetone rather than acetophenone were reacted with phenylmagnesium bromide followed y hydrolysis of the intermediate
How many grams of C2H4 are needed to react with 0.133 moles of H2O?
12.0 moles of gas are in a 6.00 tank at 20.3. Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane are a=2.300 L^2*atm/mol^2 and b=0.0430 L/mol .
Calculate the ph at the equivalence point for the following titration 0.20M HCl versus 0.20M methylamine (CH3NH2). The Ka of methylammonium is 2.3x10^-11.
Calculate the maximum amount of CO2 that can be produced when 64.0 g of O2 and 64.0 g of CH3 OH are mixed for the reaction 2 CH3OH + 3 O2 → 2 CO2 + 4 H2 O .
Papaverine hydrochloride (C20H21NO4HCl) is a weak acid. It is used in medicine as a muscle relaxant. A 0.205 M solution of papaverine hydrochloride has a pH = 3.31. Find the Ka of papaverine hydrochloride.
