<h3>
Answer:</h3>
The higher is its frequency.
<h3>
Explanation:</h3>
- Electromagnetic waves are types of waves that do not require a material medium for transmission.
- They include radio waves, microwaves, infra-red and gamma rays among others.
- Frequency refers to the number of complete oscillations in one second while wavelength is the distance between two successive crests or trough in a transverse wave.
- The frequency of electromagnetic waves varies inversely to the wavelength.
- Electromagnetic waves with higher frequencies such as x-rays and gamma rays have lower wavelengths.
- Those with higher wavelengths, on the other hand, such as microwaves and radio waves have lower frequencies.
Answer:
Explanation:
While trying to write the chemical formula for a compound (a neutral molecule), one must identify and exchange the charge of the cation with that of the anion to become the subscript of one other. For example
Aluminium oxide has Aluminium (Al) and oxygen (O); since Al has a charge of 3+ (the cation) and O has a charge of 2- (the anion), the compound would have it's charges as Al³⁺O²⁻ and when the charges are exchanged to there subscripts, it would form Al₂O₃; thus there would be two cations of aluminium for every three anions of oxygen in order to have a neutral molecule.
This same explanation can be given to Aluminium sulfite. Aluminium sulfite has Aluminium (Al) and sulfite (SO₃). Al has a charge of 3+ (cation) while sulfite has a charge of 2- (anion), with the compound having it's charges as Al³⁺(SO₃)²⁻ and when the charges are exchanged to there subscripts, it would form Al₂(SO₃)₃ and would thus have 2 cations of aluminium (Al³⁺) for every 3 anions of sulfite (SO₃³⁻) in order to have a neutral molecule.
Because when anything is exposed to air, it come in contact with bacteria which begin to break down the proteins in the beans. But when it’s in a can, it can’t get exposed to bacteria which means it won’t break down.
Hope this sheds some light ♥︎
