Cytochrome c is an iron-containing enzyme found in the cells of all aerobic organisms and If cytochrome c is 0.43% by mass, then  its minimum molecular weight  is 13023.2 g .

Cytochromes are the main electron carries present in the electron transport chain . Minerals associated with cytochromes are Fe and Cu .

Calculation ,

100 g of enzyme contains 0.43 g Fe

X g of enzyme will contains 56 g of Fe

∴ 0.43 × X = 5600

X =  5600 / 0.43 = 13023.2 g or 13 kg/mol

Therefore , the minimum molecular weight of the enzyme is 13023.2 g or 13 kg/mol .

The solubility of nitrogen gas at 25°C and a nitrogen pressure of 522 mmHg is 4.7 × 10 –4 mol/L. What is the value of the Henry'
Anestetic [448]

Answer:

6.8 × 10⁻⁴ mol/L.atm

Explanation:

Step 1: Given data

Solubility of nitrogen gas at 25°C (S): 4.7 × 10⁻⁴ mol/L

Partial pressure of nitrogen gas (P): 522 mmHg

Step 2: Convert the partial pressure of nitrogen to atm

We will use the relationship 1 atm = 760 mmHg.

522mmHg \times \frac{1atm}{760mmHg} = 0.687atm

Step 3: Calculate the value of the Henry's Law constant (k)

We will use Henry's law.

S = k \times P\\k = \frac{S}{P} = \frac{4.7 \times 10^{-4}mol/L }{0.687atm} = 6.8 \times 10^{-4} mol/L.atm

As a result of the transfer of an electron from a less electronegative atom to a more electronegative atom,
Viktor [21]

<u>Answer:</u> The correct answer is Option d.

<u>Explanation:</u>

Electronegativity is defined as the tendency of an element to attract the shared pair of electron towards itself in a compound.

When electron is transferred from less electronegative atom to more electronegative atom.

The atom which is more electronegative gains electron and undergoes reduction reaction.

Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

X^{n+}+ne^-\rightarrow X

During the transfer of electrons, energy is released when an electron looses is potential energy during the transfer.

Hence, the correct answer is Option d.

Consider the reaction 4FeS2 + 11O2 → 2Fe2O3 + 8SO2. If 8 moles of FeS2 react with 15 moles of O2, what is the limiting reactant?
omeli [17]

Answer:

O2

Explanation:

for find the limiting reactant you must calculate the moles of the reactants from the amount that you have and from the MM:

MM FeS2 = 120n  = 26.2g / 120g/mol = 0,218 mol

MM O2  = 32n = 5,44g/32g/mol = 0,17 mol

The limiting reactant is  

O2
