Answer:
The majority of the molecules move from higher to lower concentration, although there will be some that move from low to high. The overall (or net) movement is thus from high to low concentration.
hope this helps!<3
Standard equation would be N2(g)+3H2(g)==>2NH3(g), so through stoichiometry, (4 mol N2)(2mol NH3/1 mol N2), assuming excess H2, would yield 8 moles of NH3.
The group of atoms held together by covalent bonds is called a molecule
this shows that magnesium is higher in the reactivity series than lead.
I don't think there can be an ionic equation written because both components are in solid form and neither is in an aqeuos state.
