Oxigen acts like as the final electron acceptor at the end of the electron transport chain
Answer:
0,07448M of phosphate buffer
Explanation:
sodium monohydrogenphosphate (Na₂HP) and sodium dihydrogenphosphate (NaH₂P) react with HCl thus:
Na₂HP + HCl ⇄ NaH₂P + NaCl <em>(1)</em>
NaH₂P + HCl ⇄ H₃P + NaCl <em>(2)</em>
The first endpoint is due the reaction (1), When all phosphate buffer is as NaH₂P form, begins the second reaction. That means that the second endpoint is due the total concentration of phosphate that is obtained thus:
0,01862L of HCl×= 1,862x10⁻³moles of HCl ≡ moles of phosphate buffer.
The concentration is:
= <em>0,07448M of phosphate buffer</em>
<em></em>

Answer:
Look at the picture.
Explanation:
On stage one binding of a substrate occurs (and also the geometry of active site may change) and water comes to the site. On stage two the hydrolisis takes place and on stage 3 products deabsorb from the enzyme.
Answer:
Molar concentration of solution = 0.0056 moles / liter
Explanation:
Looking at the chemical reaction we realize that the precipitate, formed by adding the iron powder, is cooper.
Then for finding the number of moles of precipitated copper:
From the chemical reaction we deduce that moles of Cu equals to moles of in the initial solution.
So molar concentration is defined as:
