Water is a polar molecule because it has two polar single bonds and also it has bent shape structure.
Since the oxygen atom of water has two lone pair of electrons and also dipole moment is more towards the oxygen atom. As a result, there will be increase in electron density across the oxygen atom which will induce a negative charge on oxygen and positive charge on hydrogen atom.
Here, we should use combined gas law which can be derived from combined gas law, “PV=nRT”. Rearranging, we can get PV/T=nR. Then we can set the two states in the problem together to get
Hydrogen is the limiting reactant because when doing a stoichiometry equation for the reactants, hydrogen will be used completely by having a smaller yield and oxygen will be excess (7 moles to be exact)
Nitrogen, the next nonmetal, has 5 electrons in the valence shell, so it needs to combine with 3 hydrogen atoms to fulfill the octet rule and form a stable compound called ammonia (NH3).
