Answer:
<h2>Density = 12.5 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
From the question
mass = 52.5 g
volume = 4.2 mL
Substitute the values into the above formula and solve for the density
We have
We have the final answer as
<h3>Density = 12.5 g/mL</h3>Hope this helps you
Answer:
The He₂ 2+ ion is more stable since it has a higher bond order (bond order = 1) than the He₂ + ion (bond order = 1/2).
Explanation:
Molecular orbital of He₂⁺
There are two electrons in bonding and 1 electron in antibonding orbital
Bond order =
=
Molecular orbital of He₂⁺²
There are two electrons in bonding and 0 electron in antibonding orbital
Bond order =
= 1
So bond order of He₂⁺² is 1 which is more stable than He₂⁺ whose bond order is .
