The decomposition of ammonia gas (a process that occurs at high temps) is 2kh3(g) --> n2(g) 3h2(g). if a balloon was filled with 3.5l of ammonia gas and all of the gas decomposed, what would be the total volume of gas in the container? assume the pressure and temp remains constant.

Answer : The total volume of gas in the container will be, 7 liters

Explanation :

The given balanced chemical reaction is,

From the balanced chemical reaction we conclude that

2 mole of ammonia gas decomposes to give 1 mole of nitrogen gas and 3 moles of hydrogen gas.

According to the Avogadro's Law, the volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature.

or,

where,

= initial volume of ammonia gas = 3.5 L

=  total volume of gas in the container = ?

= initial moles of ammonia gas = 2 mole

= final moles of all gas (nitrogen + hydrogen) = (1 + 3) = 4 moles

Now put all the given values in the above formula, we get the total volume of gas in the container.

Therefore, the total volume of gas in the container will be, 7 liters

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
