Answer: The name of the is Iodine tetrabromide and it is a covalent compound.
Explanation:
Inter-halogen compounds are compounds which composed of two different halogen atoms. For example ; etc.
The naming is done by first writing the central atom symbol's name followed by the prefix corresponding to the number of atoms of another halogen atom like: Mono for 1, di ,for 2 tri for 3, tetra for 4 , penta for 5 etc. After this name of the another halogen is written with suffix 'ide' in the end.
The name of the is Iodine tetra bromide.
In halogen compounds, the difference in electronegativities is not so large due to which they form covalent compounds by the means of sharing the electrons. Hence the Iodine tetrabromide covalent compound.
<u>Answer:</u> The change in internal energy of the gas is 108.835 kJ
<u>Explanation:</u>
To calculate the work done for reversible expansion process, we use the equation:
where,
W = work done
P = pressure = 1.03 atm
= initial volume = 3.00 L
= final volume = 11.0 L
Putting values in above equation, we get:
(Conversion factor: 1 L. atm = 101.325 J)
Calculating the heat from power:
where,
Q = heat required
P = power = 150 W
t = time = 12 min = 720 s (Conversion factor: 1 min = 60 s)
Putting values in above equation:
The equation for first law of thermodynamics follows:
where,
Q = total amount of heat required = 108 kJ
dU = Change in internal energy = ?
W = work done = -0.835 kJ
Putting values in above equation, we get:
Hence, the change in internal energy of the gas is 108.835 kJ
