Answer:
Waves; wavelength; electromagnetic energy; ultraviolet light.
Explanation:
Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.
Sound travels faster through solids than it does through either liquids or gases.
Lightwave can be defined as an electromagnetic wave that does not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
Hence, sound and light are both found as waves, with a variety of wavelengths. The sun, a source of light waves specifically, releases a type of electromagnetic energy. It can be found as UVA or UVB types. These lights give off different levels of ultraviolet light, some of which can be harmful.
Additionally, the ultraviolet spectrum is divided into three categories and these are; UVA, UVB ,and UVC.
Concentration (m) signify 'molality'
Concentration (M) signify 'Molarity'
Formula for molality (m) = 
In the question denisty of solute is not given so we can calculate concentration (M) that is 'Molarity'
Molarity (M) = 
Moles of solute CH3OH = Given grams / Molar mass of CH3OH
Given grams of CH3OH = 12.9 g and molar mass = 32.0 g/mol
Moles of solute CH3OH = 
Moles of solute CH3OH = 0.403 mol
Volume of solution = 230 mL , we need to convert 230 mL to 'L'
Volume = 
Volume = 0.23 L
Molarity (M) = 
Concentration (M) = 1.75 mol / L or 1.75 M
Saturated had as much solute that it can hold, supersaturated holds more than can normally be dissolved.
Answer:
8H2SO4 + 2KMnO4 + 5Na2O2 => 8H2O + 2MnSO4 + 5Na2SO4 + 5O2 + K2SO4
