Ammonia burns in oxygen gas to form nitric oxide (NO) and water vapor. How many volumes of NO are obtained from six volumes of ammonia at the same temperature and pressure

6 volumes of NO

Explanation:

First, let us write a balanced equation for the reaction between between ammonia and oxygen to nitric oxide and water vapour. This is illustrated below:

4NH3 + 5O2 —> 4NO + 6H2O

From the balanced equation,

4 volumes of NH3 produced 4 volumes of NO.

Therefore, 6 volumes of NH3 will also produce 6 volumes of NO.

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.
