Find the volume of the cylinder. Use 3.14 for s. Round your answer to the nearest hundredth.
serg [7]

Answer:

2255.31 cu.m

Step-by-step explanation:

Volume of a cylinder = πr²h

Given radius r = 6.5m

Height h = 17m

Volume = π × 6.5²×17

Volume = 3.14×6.5²×17

Volume of the cylinder = 2255.31cu.m

Consider an ionic compound, MX, composed of generic metal M and generic, gaseous halogen X.
Art [367]

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
