Answer :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule. The electrons are represented by dot.
The given molecule is, perbromate ion.
Bromine has '7' valence electrons and oxygen has '6' valence electron.
Therefore, the total number of valence electrons in perbromate ion, = 7 + 4(6) + 1 = 32
According to Lewis-dot structure, there are 14 number of bonding electrons and 18 number of non-bonding electrons.
Formula for formal charge :
The Lewis-dot structure of perbromate ion is shown below.
Answer:
The first thing we have to do is change and state all the units so that we can use our ideal gas law equation ().
650 mmHg is a pressure unit, we have to convert this to kiloPascals. We know that 760 mmHg gives us 101 kPa.
P = 86kPa
T = 15°C + 273K = 288K
R (Gas constant) = 8.31 kj/mol
Molar mass of Ammonia () = (1 x 3) + (14) = 17g/mol
n (moles) =
3.34 mol
V = ?
Rearrange the equation to solve for Volume:
Substitute the values inside:
V =
<u>Therefore 93 L of volume is occupied by the ammonia gas.</u>
