In a face-centered cubic structure, every atom has twelve neighbors. which arrangement of balls serves as the best model for thi
s structure? twelve balls arranged equally apart from each other around a circle eight balls at the corners of a cube eight balls at the corners of a cube, and one ball in the center of the cube eight balls at the corners of a cube, and six balls in the centers of the cube's faces description
1 answer:
The image attached below is the correct representation of a face-centered cubic unit cell model. To create this model, you have to place 6 balls in the centers of each of the cube's faces and 1 ball for every corner of the cube which sums up to 8 balls. Therefore, the answer is: <span><em>eight balls at the corners of a cube, and six balls in the centers of the cube's faces.</em></span>

Answer:
Rate of formation of SO₃ = 7.28 x 10⁻³ M/s
Explanation:
According to equation 2 SO₂(g) + O₂(g) → 2 SO₃(g)
Rate of disappearance of reactants = rate of appearance of products
⇒ -----------------------------(1)
Given that the rate of disappearance of oxygen = = 3.64 x 10⁻³ M/s
So the rate of formation of SO₃ = ?
from equation (1) we can write
⇒ = 2 x 3.64 x 10⁻³ M/s
⇒ = 7.28 x 10⁻³ M/s
∴ So the rate of formation of SO₃ = 7.28 x 10⁻³ M/s
