Answer:
d - orbital
Explanation:
The d-orbital can modelled by a peanut shape.
A peanut shape closely resembles the shape of a double dumb-bell shape. The double dumb-bell shape is like that of a peanut.
- The s-orbital has a spherical shape.
- p - orbital is dumb-bell shaped
- d - orbital is a double dumbell
- f - orbital has a complex shape.
Therefore, since a peanut is like a double dumb-bell, it clearly models the d-orbital.

<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
8.71803 mol PbO₂ ≈ 8.72 mol PbO₂
Warming hand over a radiator is called radiation
Answer:
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
