Answer:
- the electromagnetic spectrum is the range of electromagnetic radiation, organized by how much energy the radiation carries. there is an opposite relationship between wavelength, frequency, and energy. as the wavelength of a wave increases, the frequency and energy decrease, and vice versa.
- the order from longest wavelength (lowest energy) to shortest wavelength (highest energy) is as follows: radio waves, microwaves, infrared waves, visible light waves, ultraviolet waves, x-rays and gamma rays.

You can
Explanation:
The concentration doesn't change when its equals out.
Answer:
7.
Explanation:
A neutral solution has a pH=7.
A basic solution has a pH>7.
An acidic solution has a pH<7.
The number of carbon atoms in an alcohol affects its solubility in water, as shown in Table 13.3. As the length of the carbon chain increases, the polar OH group becomes an ever smaller part of the molecule, and the molecule becomes more like a hydrocarbon. The solubility of the alcohol decreases correspondingly.
