The barometric pressure measured outside an airplane at 3 km ( ft) was 524 mmHg. Calculate the pressure in kPa.
NeX [460]

Answer:

69.8609 KPa.

Explanation:

The following data were obtained from the question:

Pressure (in mmHg) = 524 mmHg.

Pressure (in KPa) =?

Thus we can obtain the pressure in KPa as follow:

760 mmHg = 101.325 Kpa

Therefore,

524 mmHg = 524 mmHg × 101.325 KPa / 760 mmHg

524 mmHg = 69.8609 KPa

Thus, 524 mmHg is equivalent to 69.8609 KPa.

Br₂ + FeBr₃----->Br-Br-FeBr₃  

In this reaction,  FeBr₃, is a electron-deficient species that is it act as a lewis acid.

While Br₂, donates its electron to  FeBr₃.

Br₂, act as a electrophile while FeBr₃ is a lewis acid.

Futher if Br₂, undergoes a reaction an aromatic ring , then that ring will attack Br₂, and it acts as a electrophile.
