What volume of gas (H2 and O2 combined) at STP is released by decomposition of 93.405g of H2O? 2H2O (l)<--> 2H2(g) + O2(g)
Treatment of D, first with aqueous acid and then with KMnO4, yields 2 carboxylic acids identified as acetic acid and pentanoic acid. (KMnO4 cleaves 1,2-diols to yield carboxylic acids.) Propose a structure for compound D. Don't worry about sterioc..
The reaction can be represented as {\rm 2 NI_3 (s)\rightarrow N_2 (g) + 3 I_2 (g)},~{{\Delta H}}_{\rm rxn} = -290.0~{\rm kJ} Find the change in enthaply when 16.0g of \rm NI_3 decomposes.
