The balanced chemical reaction is:
<span>C + H2O → CO + H2
</span>
We are given the amount of carbon to be used in this reaction. This will be the starting point of the reaction.
<span>34 g C ( 1 mol C / 12.01 g C ) ( 1 mol H2/ 1 mol C) (2.02 g H2 / 1 mol H2) = 5.72 g H2
Apparently, the correct answer is not in the given choices.</span>
Answer : The pH of calcium acetate solution will be 9.38.
Explanation : When calcium acetate dissocates completely in solution to form Calcium(+2) ions and two acetate ions, this gives the acetate ion concentration as
(2 X 0.51 M) = 1.02 M
Acetate ion then hydrolyzes as follows;
:
Now, Kb will be =
/ ![[C_{2}H_{3}O_{2}^{-}]](https://tex.z-dn.net/?f=%5BC_%7B2%7DH_%7B3%7DO_%7B2%7D%5E%7B-%7D%5D%20)
= Kw / Ka
= 1 x
/ 1.8 x
= 5.6 × 
= 2.4 ×
Now, we know , pOH = -log
= 4.62
So, the pH = 14 - pOH = 14 - 4.62 = 9.38
It's Hemoglobin- i just took test
Yes because plants are a source of food for some animals
