Answer:
The three types of nuclear radiation in increasing order of penetrating power are ____.
alpha, beta, gamma
Explanation:
Alpha Ray: This has the least penetrating power because the particles produced during decay are large in quantity but they have a very low energy which dosent alow them to move far through space because the are ususally blocked.
Beta ray : they have more penetrating power than alpha rays because they a bit higher in energy and quantity {size}
Gamma Ray; this has the most penetrating power. they are highly powerful waves but do little at ionization of other atoms or molecules. it penetrates through molecules very easily due to its size and energy.
The answers D) -60
Just subtract
Formula: NA2S2O3. Valency: 2
Answer:
All liquid glow products depend on a chemical process known as CHEMILUMINESCENCE to produce their light. Chemiluminesence is a chemical reaction that causes a release of energy in the form of light. To produce this light the electrons in the chemicals become excited and rise to a higher energy level.To utilise this process glowsticks contain two liquids; hydrogen peroxide and tert-butyl alcohol. When mixed together it is these liquids that create the glow. Fluorescent dyes are also used in the alcohol to alter the colour of the light emitted. Chemiluminesence is a chemical reaction that causes a release of energy in the form of light.
