Explanation:
The shorthand is made using the lowest & closest noble gas, and picking up where it leaves off as follows, and longhand is made from a followed pattern you can easily find
Ur moms the density of mercurio
Answer:
b) Both p orbitals are perpendicular to the F−Be−F bond axes.
Explanation:
Be has 2 electrons in its valence shell, subshell s is fulfilled, so it has no unpaired electrons in its ground state to make bonds with F. So, it can promote the electrons to the 2p orbital and will having sp hybridization.
The bond between the orbitals sp and the p orbital of F are in opposite directions but the same ax. The two bonds are equivalent, and the molecule had a linear geometry. The two unhybridized p orbitals on Be are vacant, and so they are perpendicular to the F-Be-F bond axes.

okay let me know when i can help, ill be happy too help
Answer:
6.9 hours
Explanation:
In order to solve this problem we'll<u> convert 837 km to miles</u> (another option would be to convert 75 mi/hr to km/hr). To make said conversion we'll use the given <em>conversion factor</em>:
- 837 km *
= 519.88 mi
Finally we <u>calculate the time required to travel said distance</u> at a constant speed of 75 mi/hr:
- 519.88 mi ÷ 75 mi/hr = 6.9 hr
