37. Using the reaction of nitrogen gas and hydrogen gas to make ammonia gas (NH3), if you have 7 L of nitrogen, and all the hydrogen you need, how many
liters of ammonia gas can you make?

You can make 14 L of Ammonia

Avogadro's hypothesis:  

In the same T,P and V, the gas contains the same number of molecules  

So the ratio of gas volume will be equal to the ratio of gas moles  

Reaction

N₂+3H₂⇒2NH₃

Volume of Nitrogen-N₂ : V₁=7 L

From the equation above, mol ratio of N₂ : NH₃ =1 : 2, so volume of NH₃ :

i believe that it is a exoplanet

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

hope i !
