Consider the equation for the formation of water. 2h2 + o2 > 2h2o what is the theoretical yield of h2o if 130 g of h2o is produced from 18 g of h2 and an excess of o2?

The theoretical yield is 160 g H₂O.

Moles of H₂ = 18 g H₂ × (1 mol H₂/2.016 g H₂) = 8.93 mol H₂

Moles of H₂O = 8.93 mol H₂O × (2 mol H₂O/2 mol H₂) = 8.93 mol H₂O

Theoretical yield of H₂O = 8.93 mol H₂O × (18.02 g H₂O/1 mol H₂) = 160 g H₂O

h let me think

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.

if it's not useful, feel free to report for mistake in answer.
