What is oxidation reaction? In the reaction. Fe2O3+2Al=Al2O3+2Fe . Identify the reactant. 1) that is oxidised. 2) that is reduced. 3) that is reducing agent

oxidation reaction is the process of electron loss.

1. The reactant oxidised is Al

2. The reactant reduced is Fe2o3

3. The reducing agent is Al

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)

explanation:

asking the goog might u get an answer
