Kinetic data for a reaction, A → B, was measured and the same data were plotted in three different ways. The results of the plots are below. Plot 1
A plot of [A] versus time had a line of best fit as
y = –.0505 x + 0.275 R2 = 0.98493

Plot 2
A plot of ln [A] versus time had a line of best fit as
y = –0.0026 x – 1.290 R2 = 0.99997

Plot 3
A plot of $$
versus time had a line of best fit as
y = 0.00001 x + 3.636 R2 = 0.98653

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:

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
