Explanation:
Assuming that moles of nitrogen present are 0.227 and moles of hydrogen are 0.681. And, initially there are 0.908 moles of gas particles.
This means that, for
moles of + moles of
= 0.908 mol
Since, 2 moles of =
= 0.454 mol
As it is known that the ideal gas equation is PV = nRT
And, as the temperature and volume were kept constant, so we can write
=
=
=
= 5.2 atm
Therefore, we can conclude that the expected pressure after the reaction was completed is 5.2 atm.
If you look at the periodic table you will see the atomic number (the smaller number) which is 3. that identifies how many protons there are. since the lithium is neutral that means there’s a same amount of electrons.
therefore there’s 3 electrons and 3 protons
therefore there’s 3 electrons and 3 protons
