Explanation:

Poison ivy is also called toxicodendron radicals. It is a poisonous plants found in Asia and North America. Also poison oak which is known as toxicodendron diversilobum is found in North America. The both plants are known to cause an itchy, irritating and painful rash when an individual makes a skin contact with it. This is because the plant sap contains an oily mixture of organic compound known as urushiol. In order to effectively remove the oily compound and prevent any reaction from occurring, soap and water is used to wash and rinse the affected area. Recently dermatologist has started recommending baking soda to ease the itching reactions. I hope this helps. Thanks!

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)
