Water can be formed in the following reaction: 2h2+o2--> 2h2o, if you have 6 moles of oxygen gas (o2), how many moles of water can you form? (assume you have an excessive amount of hydrogen {h2}? (enter just the number; not the number and units) your answer

Answer

12

Explanation

We have a balanced chemical equation from the question that depicts the formation of water.

                                                  2H2+O2-->2H2O,

We can clearly see from the equation that, the formation of 2 moles of water molecules requires the input of 2 moles of hydrogen and 1 mole of Oxygen.

So indirectly, it tells that the moles of water molecules will be double of the moles of Oxygen molecules used in the reaction.

So if we say that 6 moles of oxygen is used and the reaction is going in such a way that hydrogen is not a limiting reactant, then 12 moles of water will be produced.

Hope it help!

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.
