What is the volume of a salt crystal measuring 2.44 × 10–2 m by 1.4 × 10–3 m by 8.4 × 10–3 m?
Dima020 [189]
All solids have an orderly internal structure with repeating bonding patterns between atoms, ions, or molecules. They are called crystal lattices. They are a 3-dimensional arrangement of atoms inside a crystal. The volume of this crystal is:
<span>
Volume = 2.44 × 10^–2 m x 1.4 × 10^–3 m x 8.4 × 10^–3 m = </span>2.87 x 10^-7 m^3

When 1 mol CS2(l) forms from its elements at 1 atm and 25°C, 89.7 kJ of heat is absorbed, and it takes 27.7 kJ to vaporize 1 mol
Kitty [74]

Answer:

There is 117.4 kJ of heat absorbed

Explanation:

<u>Step 1: </u>Data given

Number of moles CS2 = 1 mol

Temperature = 25° = 273 +25 = 298 Kelvin

Heat absorbed = 89.7 kJ

It takes 27.7 kJ to vaporize 1 mol of the liquid

<u>Step 2:</u> Calculate the heat that is absorbed

C(s) + 2S(s) → CS2(l)    ΔH = 89.7 kJ  (positive since heat is absorbed)

CS2(l) → CS2(g)           ΔH = 27.7 kJ  (positive since heat is absorbed)

We should balance the equations, before summing, but since they are already balanced, we don't have to change anything.

C(s) + 2S(s)---> CS2 (g)

ΔH = 89.7 + 27.7 = 117.4 kJ

There is 117.4 kJ of heat absorbed

scientists want to place a telescope on the moon to prove their view of distant planets. The telescope weighs 200 pounds on Eart
vova2212 [387]
The weight itself technically will not change. The pull of gravity lessens, making it appear that it is lighter on the moon.
