Ph= - log [H+] = -log 1.00× 10-7 = -(log 1 + log 10-7) = -( 0 + (-7log 10) = -( -7) = 7
For a given peak intensity of radiation of a star that occurs at a wavelength of 2 nanometers, this is located at the spectral band of an X-ray. An X-ray's wavelength typically goes from 0.1 nano meters to 10 nano meters. Given that, the wavelength of the star fits perfectly into the range of an X-ray

Answer:
Gaseous solution isn't dense, neither the solid, but liquid is denser
Explanation:
Gas: only gases are dissolved under a given set of conditions.Since interactions between molecules play almost no role, dilute gases form rather trivial solutions. In part of the literature, they are not even classified as solutions, but addressed as mixtures.
Liquid: If the solvent is a liquid, then almost all gases, liquids, and solids can be dissolved.
Solid: Solid solution is less denser than liquid.
