How many moles of ammonia gas can be formed from 14.0 L of hydrogen gas 300 K and a pressure of 2.0 atm

n = 1.14 mol

Explanation:

Hello there!

In this case, according to the ideal gas law:

It is possible to solve for the moles of the gas given the volume, temperature and pressure:

Thus, we plug in 14.0 L, 300 K and 2.0 atm to obtain:

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
