iron salts react with water to form hydrated iron ( III ) oxide which is basically rust
hope that helps :)
Because ionic bonds form between oppositely charged particles. Opposit s attract.
If that’s not correct, give me the options and I can try to help further.
There are some methods that differentiate waves; one thing is by its medium.
Electromagnetic waves did not require a medium for transmission such as in a
vacuum while mechanical waves require a medium to travel such as air, water or
anything that can serve as a transmission aid.
The most common sample of EM waves in
telecommunication is radio,
light and infra-red signals. An example of a mechanical wave is a sound
wave, which requires air to travel. Oscillating molecules made the
sound waves.

<h2>D.
They contain the same number of elements.</h2>
Explanation:
The formula (Ba(NO3)2) contains 9 atoms.
1 Barium atom (Ba)
Contains 2 NO3 groups -
2 Nitrogen atoms (N) x 2
6 Oxygen atoms (O3) x 2
3 Elements in total
The formula (Sc(NO3)3) contains 13 atoms.
1 Scandium atom (Sc)
Contains 3 NO3 groups -
3 Nitrogen atoms (N) x 3
9 Oxygen atoms (O3) x 3
3 Elements in total
They do not have the same number of atoms.
They do not have the same number of oxygen atoms.
They do not contain the same number of NO3 groups.
They do have the same number of elements.
