The given figure is Lewis structure of BrF₃ and its polarity.
A Lewis structure is based on the concept of the octet rule, in which atoms share electrons so that each atom has eight electrons in its outer shell.
Lewis structures, also known as Lewis-dot diagrams, show the bonding relationship between atoms of a molecule and the lone pairs of electrons in the molecule. Lewis structures can also be useful in predicting molecular geometry in conjuntion with hybrid orbitals.
Net dipole moment of this molecule is not zero. Hence, this is polar molecule.

True, oxygen gas ignites a glowing splint
Answer : The density of a sample of chlorine gas is, 12.59 g/L
Explanation :
To calculate the density of chlorine gas we are using ideal gas equation.
where,
P = pressure of chlorine gas = 4.5 atm
V = volume of chlorine gas = 12.6 L
n = number of moles of chlorine gas
w = mass of chlorine gas
R = gas constant = 0.0821 L.atm/mol.K
T = temperature of chlorine gas =
M = molar mass of chlorine gas = 71 g/mol
Now put all the given values in the above formula, we get:
Therefore, the density of a sample of chlorine gas is, 12.59 g/L
