Chemistry
1 answer:
dezoksy [38]4 years ago

<u>Answer</u>:

"The arrangement of atoms or ions in a crystal " is described by the terms body-centered cubic and face-centered cubic.

<u>Explanation</u>:

Face centred cubic system explains the crystal structure where an atom is present at each cubic corner of the crystal  and the centre of each cube face. Meaningfully, a closed packed plane where at each "face of the cube" atoms touch the alongside face diagonals.

Whereas in body centric cube system has the lattice point present at the 8 corners of  cell and an additional one at the center of the cell. Thus, both explains how the atom or ions are  placed or arranged in a crystal.

Answer is: concentration of chlorine is 1418.34 M.

Balanced chemical reaction: PCl₃(g) + Cl₂(g) → PCl₅(g).
[PCl₃<span>] = 0.33 M; equilibrium concentration of phosphorus trichloride.
</span>[PCl₅<span>] = 0.44 M; equilibrium concentration of phosphorus pentachloride.
</span>Keq = 0.00094.
Keq = [PCl₅] ÷ [PCl₃] · [Cl₂<span>].
</span>[Cl₂] = [PCl₅] ÷ Keq · [PCl₃].
[Cl₂] = 0.44 M ÷ 0.33 M · 0.00094.
[Cl₂] = 1418.43 M.

Under the conditions of 775 torr of pressure and 30 °C temperature,
docker41 [41]

Answer:

31 ml

Explanation:

At constant temperature of 30°C;

Using Boyles Law:

P1V1 = P2V2

775 × 30 = 750V2

V2 = (775 × 30) / 750 = 31ml
