Question: As an instructor is preparing for an experiment, he requires 225 g phosphoric acid. The only container readilyavailable is a 150-mL Erlenmeyer flask. Is it large enough to contain the acid, whose density is 1.83 g/mL?
Does the standard enthalpy of formation of \({{\bf{H}}_{\bf{2}}}{\bf{O}}\left( {\bf{g}} \right)\)differ from 螖H掳 for the reaction \({\bf{2}}{{\bf{H}}_{\bf{2}}}\left( {\bf{g}} \right){\bf{ + }}{{\bf{O}}_{\bf{2}}}\left( {\bf{g}} \right) \to {\bf{2}}{{\bf{H}}_{\bf{2}}}{\bf{O}}\left( {\bf{g}} \right)\)?
