The electrolysis of water forms H2 and O2. 2H2O Right arrow. 2H2 + O2 What is the percent yield of O2 if 10.2 g of O2 is produced from the decomposition of 17.0 g of H2O? Use Percent yield equals StartFraction actual yield over theoretical yield EndFraction times 100.. 15.1% 33.8% 60.1% 67.6%

can you attach a picture of the lettuce? : )

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
