Jasper made a list of the properties of electromagnetic waves. identify the mistake in the list.

1. are made up of an electric field and a magnetic field
2. are longitudinal waves
3. can travel through space
4. all travel at the same speed in a vacuum

a. line 1 has a mistake
b. line 2 has a mistake
c. line 3 has a mistake
d. line 4 has a mistake

B. Line 2 has a mistake

Explanation:

1. All electromagnetic waves are made of both electric and magnetic fields (hence the name electromagnetic).

2. All electromagnetic waves are transverse, and not longitudinal.

3. All electromagnetic waves can travel through space because they do not need particles to travel (like sound waves).

4. Electromagnetic waves all travel at the speed of light (299 792 458 m/s).

answer

the ions in solute supperate from eachouthere

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
