The components of poison ivy and poison oak that produce the characteristic itchy rash arc catechols substituted with long-chain alkyl groups. If you were exposed to poison oak which of the treatments below would you apply to the affected area? a. Wash the affected area with cold water b. Wash the affected area with soap and water c. Wash the affected area with dilute vinegar or lemon juice d. Wash the affected area with soap, water, and baking soda (sodium bicarbonate)

If exposed to poison oak the most effective treatment procedure to follow is option D [Wash the affected area with soap, water, and baking soda (sodium bicarbonate)]

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!

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.
