Which of the following best desribes the conditions created by el nino
a. winds that are normally blow to the east get stronger, waters off the coast of north america cool down, and upwelling increases, improving the nutrients in the water
b. winds that are normally blow to the east slacken, waters off the coast of north america warm up, and upwelling decreases, reducing the nutrients in the water
c. wind that are normally blow to the west get stronger, waters off the coast of south america cool down, and upwelling increases, improving the nutrients in the water
d. winds that are normally blow to the west slacken, water off the coast of south america warm up, upwelling decreases, reducing the nutrients in the water

C. Wind that are normally blow to the west get stronger, waters off the coast of South America cool down, and upwelling increases, improving the nutrients in the water

Explanation:

Hope this helps :)

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
