Answer:
what?
Step-by-step explanation:
<span>The formula actual yield /
theoretical yield is used to calculate the percent yield of a reaction.
This value is a measure of how much product is produced relative to the what is
supposed to be produced. We calculate as follows:
Percent yield = </span> actual yield / theoretical yield x 100
Percent yield = 695.2 g ( 1 mol / <span>158.034 g) / 5 x 100
</span>Percent yield = 88% <------OPTION C
It would take you 15 minutes
We have
f(x) = 1/x+5,
g(x) = 5x+1/x -------> (5x²+1)/x
<span>
1) find the f(g(x))
</span>f(g(x))=(1/(5x²+1)/x) +5---- > (x/(5x²+1)) +5---->(x+5*(5x²+1))/(5x²+1)
(x+25x²+5)/(5x²+1)---------- > (25x²+x+5)/(5x²+1)
f(g(x))= (25x²+x+5)/(5x²+1)--------> is not x
therefore
<span>f(x) and g(x) are not inverses of each other
</span>the domain of the composition f(g(x)) is (-∞,∞)
2) find the g(f(x))
g(f(x))=(5(1/x+5,)²+1)/(1/x+5,)------- > (5/x²)+(10/x)+25+(x/(5x+1))
[5*(5x+1)+10x*(5x+1)+25x²*(5x+1)+x³]/[x²*(5x+1)]
the domain of the composition g(f(x)) is (-∞, -1/5) U (-1/5,0) U (0,∞)
