I believe the answer is 83.5 this may be wrong and if so I apologize in advance.
Answer:
i really dont know
Step-by-step explanation:
Answer:
hundred thousand
Step-by-step explanation:
If we start at 9 the place values go: ones(9), tens(2), hundreds(5), thousands(0), ten thousands(8), hundred thousands(3), and millions(7)
As the given values are
<span>ΔHf° = –423 kJ/mol
</span>ΔHsub = 119 kJ/mol
IE = 469 kJ/mol
ΔHEA = –301 kJ/mol
BE = 161 kJ/mol
The lattice energy of the compound can be determined by applying formula
U = <span>ΔHf° - </span>ΔHsub - BE - IE - ΔHEA
by putting values
U = -423 - 119 - 161 - 469 - (-301)
solving further
U = -871 kJ/mol
so the lattice energy is 871 kJ/mol
hope it helps
