Bromine pentafluoride BrF5 is a good example of inter halogen molecule
Snezhnost [94]

Answer:

a) The lewis dot structure is shown in the image attached to this answer

b) The formal charge on each of the atoms is zero

c) bromine has an oxidation state of +5 while fluorine has an oxidation state of -1

d) 90 degrees

e) Square Pyramidal

f) polar bonds

g) polar molecule

Explanation:

The molecule BrF5 has a formal charge of zero. It exhibits an sp3d2 hybridization state with a square pyramidal geometry. The bond angle in the molecule is 90 degrees. It is a molecule of the type AX5E. The oxidation state of bromine is +5 while that of fluorine is -1.

The Br-F bonds are polar. The overall molecule is polar due to asymmetric charge distribution concentrating on the central atom since the molecule is square pyramidal.

That all the energy of the universe remains constant, is conserved, neither created nor destroyed, but may change form is a stat
Yakvenalex [24]

Answer: First Law of Thermodynamics

Explanation:

According to first law of thermodynamics, energy of a closed system remains conserved and thus energy can neither be created nor be destroyed, it can only transform from one form to another.

\Delta U=w+q

\Delta U = change in internal energy

q= heat absorbed or released

w= work done by or on the system

Thus change in energy is brought by work or heat which are also forms of energy. Thus energy gets transformed from one form to another and neither gets created or destroyed.
