(Na2Cr2O7) all the numbers are bellow not over
Explanation:
Balanced chemical reaction equation will be as follows.
![2Fe^{2+}(aq) + 2H^{+}(aq) \rightleftharpoons 2Fe^{3+}(aq) + H_{2}(g)](https://tex.z-dn.net/?f=2Fe%5E%7B2%2B%7D%28aq%29%20%2B%202H%5E%7B%2B%7D%28aq%29%20%5Crightleftharpoons%202Fe%5E%7B3%2B%7D%28aq%29%20%2B%20H_%7B2%7D%28g%29)
In human body, the neutral iron changes into
(aq) cation. There will be an oxidation-half reaction and a reduction-half reaction. Equations for this reaction are as follows.
Oxidation: 2Fe^{2+}(aq) \rightleftharpoons 2Fe^{3+}(aq) + 2e^{-}[/tex] .... (1)
Reduction:
...... (2)
On adding both equation (1) and (2), the overall reaction equation will be as follows.
![2Fe^{2+}(aq) + 2H^{+}(aq) \rightleftharpoons 2Fe^{3+}(aq) + H_{2}(g)](https://tex.z-dn.net/?f=2Fe%5E%7B2%2B%7D%28aq%29%20%2B%202H%5E%7B%2B%7D%28aq%29%20%5Crightleftharpoons%202Fe%5E%7B3%2B%7D%28aq%29%20%2B%20H_%7B2%7D%28g%29)
Therefore, neutral iron is a part of Heme - b group of Hemoglobin and in an aqueous solution it dissolutes as a part of Heme group. Hence, then it becomes an
cation.
Answer:
How to convert 45 gal to kg? You can use the following formula to convert from Gallon to Kilograms :
X(kg) = y(gal) / 0.264172053
To convert 45 Gallon to Kilograms:
X(oz) = 45(gal) / 0.264172053
Answer: 170.3435 kg
iron Presence of trace elements, irradiation and iron impurities give the gem amethyst its purplish color!
I’d say for the answer 13.13 mmHg?
