In the redox fueling reaction, succinate + nad ↔ fumarate + nadph, the succinate molecule is undergoing which process?
GarryVolchara [31]

The answer is oxidation.

That is in the redox fueling reaction,  

succinate + NAD ↔fumarate + NADPH, the succinate molecule is undergoing oxidation.

As succinate molecule is providing electrons to NAD, so that it can be reduced from NAD to NADPH. So it is losing electrons and undergoing oxidation.

So the answer is oxidation.

The empirical formula of pyrogallol is C2H2O. Its molar mass is 126 g mol-1. What is the molecular formula?C4H4O2C2H6O3C6H6O3C2H
VARVARA [1.3K]

Answer:

The molecular formula of pyrogallol is: C6H6O3

Explanation:

<u>Step 1:</u> Data given

Empirical formula of pyrogallol is C2H2O

Molar mass of pyrogallol = 126 g/mol

Molar mass of Carbon (C) = 12 g/mol

Molar mass of hydrogen (H) = 1.01 g/mol

Molar mass of oxygen (O) = 16 g/mol

<u>Step 2:</u> Calculate molar mass of the empirical formula

2*12 + 2*1+ 16 = 42 g/mol

<u>Step 3: </u>Calculate the molecular formula

To find the molecular formule , we should multiply the empirical formula by n

n can be found by dividing molar mass of pyrogallol by the molar mass of the empirical formula

n = 126 g/mol / 42 g/mol ≈ 3

We should mulitply the empirica lformula by 3

3*(C2H2O) gives C6H6O3

if we calculate the molar mass now:

6*12 +6*1 + 3*16 = 126 g/mol

The molecular formula of pyrogallol is: C6H6O3
