Answer:

6.97 atm was the equilibrium pressure of HBr .

Explanation:

The value of the equilibrium constant =K_p=1.65\times 10^3

H_2+Br_2\rightleftharpoons 2HBr

Initially:

0             0                 7.10 atm

At equilibrium

x              x                 (7.10-2x)

The expression of equilibrium constant can be written as:

K_p=\frac{p_{HBr}}{p_{H_2}\times p_{Br_2}}

1.65\times10^3=\frac{(7.10-2x)}{x^2}

Solving for x:

x = 0.065

Partial pressure of HBr at equilibrium :(7.10 - 2 × 0.065) atm = 6.97 atm

6.97 atm was the equilibrium pressure of HBr .

Why do adults have stem cells
Eva8 [605]

Adults have stem cells because they are needed to repair certain tissues in the body such as in the muscles, bone marrow, skin, teeth, heart, and liver, to name a few. Thus, they can develop into many different cell types and function to replace older and damaged tissues.
