11. Which chemical reaction involves the fewest oxygen atoms? B.
A. 2AgNO, + K, SO4 Ag, SO4 + 2KNO,
4Fe + 6H 0 + 30,- 4Fe(OH),
C. 6002 + 6H20-CH206 + 602
D. CH, + 30, 200, + 2H, O

It should be b

Given  h(x) =  sqrt(4x  + 1), determine two functions  f  (x)  and  g(x)  which, when composed, generate  h(x).since the square root is "on" (or "around") the "4x  + 1", then the  4x  + 1  is put inside the square root. i need to take  x, do "4x  + 1" to it, and then take the square root of the result: g(x) = 4x  + 1,    f(x) =  sqrt(x), and  h(x) = (  f  o  g)(x).
