Compare a 3s orbital to a 3p orbital. Which of the following are true? I. The orbitals have the same shape. II. The orbitals hav
e different shapes. III. The orbitals have the same energy. IV. The orbitals have different energies.
1 answer:
Answer:
II. The orbitals have different shapes.
IV. The orbitals have different energies.
Explanation:
1. Shapes
Below are pictures of a 3s and a 3p orbital.
The 3s orbital has a spherical shape, and the 3p orbital has a dumbbell shape.
2. Energies
For every element except H, the order of energies is
3s < 3p
For a hydrogen atom,
3s = 3p

Equilibrium constant Kc for the reaction will be 1.722
Explanation:
O2(g)+NO(g)→CO(g)+ NO2(g)

0.88x 3.9-x x x
GIVEN:
0.88X-X= 0.11
⇒ X=0.77
CO2(g)+NO(g) → CO(g) + NO2(g)
