For the reaction N2(g) + 3H2(g) 2NH3(g), what will happen if more nitrogen gas is added?

there will be a shift towards the products

there will be a shift towards the reactants

there will not be a shift in equilibrium

the value for Keq will change

A. There will be a shift towards the products.

Explanation:

To reach chemical equilibrium, there must be a balance of reactants and products created. If you add more N2/add more reactants, the system will create more products to balance out again. So there will be a shift towards the products.

the grams   of   barium that   are in   2.3 x 10^23   atoms of barium   is   52.4 g (answer c)

    calculation

mass = moles   of ba   x molar   mass of ba

  molar mass of ba from periodic table=   137.3 g/mol

  use the   avogadro's law   constant   to   calculate the moles of barium

  that   is     1 mole =   6.02   x 10^23 atoms

                    ? moles = 2.3 x 10^23   atoms

by cross   multiplication

=(1 mole   x 2.3x 10^23 atoms)   / 6.02   x10^23 atoms)=   0.382   moles

mass   is therefore = 137.3   g/mol x 0.382 mol = 52.4 ( answer c)
