Answer:
2.4x10² kcal
Explanation:
As the serving of fish contains 50g of protein that is 4.0kcal/g:
50g × (4.0kcal/g) = <em>200kcal</em>
<em> </em>
And in 4g of fat that is 9.1kcal/g:
4g × (9.1kcal/g) = <em>36.4kcal</em>
<em />
That means the kcal of the serving are:
200kcal + 36.4kcal = 236.4kcal
In 2 significant figures: <em>2.4x10² kcal</em>
<em></em>
I hope it helps!

Answer:
Initial rate of reaction is 
.
Explanation:
It is a second order reaction.
Initial rate of reaction = ![k[O_{3}]_{0}[NO]_{0}](https://tex.z-dn.net/?f=k%5BO_%7B3%7D%5D_%7B0%7D%5BNO%5D_%7B0%7D)
, where k is rate constant, ![[O_{3}]_{0}](https://tex.z-dn.net/?f=%5BO_%7B3%7D%5D_%7B0%7D)
is the initial concentration of 
and ![[NO]_{0}](https://tex.z-dn.net/?f=%5BNO%5D_%7B0%7D)
is the initial concentration of NO.
Here, k = 
, ![[O_{3}]_{0}=5.84\times 10^{-6}M](https://tex.z-dn.net/?f=%5BO_%7B3%7D%5D_%7B0%7D%3D5.84%5Ctimes%2010%5E%7B-6%7DM)
and ![[NO]_{0}=8.65\times 10^{-5}M](https://tex.z-dn.net/?f=%5BNO%5D_%7B0%7D%3D8.65%5Ctimes%2010%5E%7B-5%7DM)
So, initial rate of reaction = 
=
So, initial rate of reaction is
The length of the flower garden is 529 centimeters.what is its length in meter?
It’s aluminum because electrons and protons are basically the same thing just in different places on a electron cloud and the atomic number is 13 so I think it’s aluminum.
