If you are doing electronic configuration for Bromine atom; then you need to put the symbol of Argon (Ar) inside the brackets because the noble gas that comes before Bromine (Br) is Argon (Ar).
CH is nonpolar
NH is polar
CCl is polar
SiO is polar
SCl is polar
CO is polar
OF is nonpolar
Remember that polarity results from unequal electron sharing
Answer:
When the electrons in the atom are excited, for example by being heated, the additional energy pushes the electrons to higher energy orbitals. When the electrons fall back down and leave the excited state, energy is re-emitted in the form of a photon
Explanation:
Answer:The final volume of nitrogen gas will be 13 L. Nitrogen gas was collected in the plastic bag.
Explanation:
Volume of the storage cylinder:
Volume of the cylinder = 
Diameter of the cylinder (d)= 6.6 cm
So, radius of the cylinder 
Height of the cylinder = 26 cm
Volume of the cylinder=
Pressure of the
gas in a cylinder =
The cylinder is opened and the gas allowed to escape into a large empty plastic bag. So, now the value of the pressure
will become equal to atmospheric pressure that 1 atm .
Volume of
gas in plastic bag
will be given by the expression of Boyle's law

On substituting the values:


The final volume of nitrogen gas will be 13.24 L when rounded of to two significant figures will be 13 L. Nitrogen gas was collected in the plastic bag.
