<span>1)false a in chemical equilibrium concentration of reactant is equal to concentration of product
2)as here they said heat is added in product side means its endothermic reaction and in endothermic reaction on increasing temp. equilibrium shift towards forward direction so its true
3) B)as here mole are equal in reactant and product side that is 2 and if we increase pressure equilibrium shift in dat direction where no. of moles are less and here mole are equal so it will remain unaffected</span>
Answer:
#2: They break down quicker than stable isotopes. - im not sure
Explanation:
Answer:

Explanation:
For this question, we must use Dalton's Law of Partial Pressures:
The partial pressure of a gas in a mixture of gases equals its mole fraction times the total pressure:

Data:
χ = 0.7808

Calculation:

The choices for this question can be found elsewhere and as follows:
<span>A. A single polypeptide may have quaternary structure.
B. Hydrogen bonds may hold the polypeptides in contact.
C. A quaternary protein cannot have fewer than two carboxyl groups.
I think the correct answer from the choices is option A. The statement a </span>single polypeptide may have quaternary structure is not true.
