The person walk 2346.95 meters in 35 minutes
<u><em>calculation</em></u>
convert miles to meters
that is 1 miles= 1609.34 meters
2.5 miles= ? meters
by cross multiplication = (2.5 miles x 1609.34 meters) / 1 miles= 4023.35 meters.
if 4023.35 meters = 1 hr= 60 min
? meters =35 min
by cross multiplication
= 4023.35 meters x 35 min/ 60 min =2346.95 meters
Here are the given:
<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 is solved using the formula:
U = <span>ΔHf° - </span>ΔHsub - BE - IE - ΔHEA
U = -423 - 119 - 161 - 469 - (-301)
U = -871 kJ/mol
Therefore, the lattice energy is 871 kJ/mol (released).
Answer:
64
Explanation:
since it's a cube all sides are equal
and to calculate volume you multiply the length by the hieght by the width
It will be the Displacement method
