In stage 2 of photosynthesis, NADP+ becomes NADPH by adding an H+. Where does the H+ come from?
Marina86 [1]
NADPH is a reduced form of NADP+. The latter features an extra hydrogen ion in its chemical structure. When NADP+ transforms into NADPH, the other hydrogen ion  is released as part of the reaction while the other hydrogen ion becomes a part of the NADPH structure. This reaction happens during photosynthesis.

What volume of NaOH(aq) would be needed to reach the equivalence point if the concentration of the added base were 0.290 M?
DiKsa [7]

Answer:

17.2mL are needed

Explanation:

<em>The pH curve for titration of 50.0 mL of a 0.100 M solution of hydrochloric acid</em>

<em />

A strong acid as HCl reacts with a strong base as NaOH producing water and a salt. The chemical equation is:

HCl + NaOH → H₂O + NaCl

<em>Where 1 mole of HCl reacts per mole of NaOH</em>

<em />

To solve this question we must find the moles of HCl added = Moles NaOH you must add to reach the equivalence point. With these moles and the molar concentration we can find the volume that would be needed as follows:

<em>Moles HCl:</em>

50.0mL = 0.0500L * (0.100moles / L) = 0.00500 moles HCl = Moles NaOH

<em>Volume NaOH:</em>

0.00500 moles NaOH * (1L / 0.290moles) = 0.0172L NaOH =

<h3>17.2mL are needed</h3>
