Draw the structures of the products of the neutralization reaction between methylamine and acetic acid. Include lone pairs on the appropriate atoms.
A volume of 25.0 mL of .100 M HCl is titrated against a .100 M NH3 solution added to it from a buret. Calculate the pH value of solution (a) after 10.0 mL of NH3 solution have been added and
Determine the limiting, excess reagent & percent yield of the reaction - How much excess reagent is left after the reaction reaches completion?
A 18.8-g mixture of nitrogen and carbon dioxide is found to occupy a volume of 13.5 L when measured at 759.1 mmHg and 25.6oC. What is the mole fraction of carbon dioxide in this mixture?
Why would the densities of the aqueous and organic phases be rather close. How is that possible.
Explain how FeBr3 assists the reaction. Br2 dissolves in a number of solvents, but we preferentially use glacial acetic acid.
Magnesium metal reacts with HCl solution, liberating H2 gas and generating Mg2+ cations in solution. A 1.695-g sample of Mg metal is added to 125.0 mL of a 4.00 M HCl solution, and the reaction goes to completion. What mass of H2 is formed
