Answer:
shortest wavelength of visible light: Violet
Energy that can be felt as heat but can't be seen: Infrared radiation
Short invisible rays that can cause damage to the eyes: Ultraviolet light
visible light with the longest wavelength: red 700
Explanation:
Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
Can be a number of things, rain fall quota, climate, population, vegetation..any of those.
Answer:
Sedimentary, metamorphic, and igneous
Explanation:
Rocks are classified into three groups, sedimentary, metamorphic, and igneous. The differences are how they are formed.
The sodium hydroxide solution and vegetable oil underwent a chemical change.
<h3><u>Explanation:</u></h3>
The reaction between a base and a fat or fatty acid is called as saponification reaction. Here the base dissociates into the cation and hydroxyl ion. The hydrogen from the fatty acid of the oil reacts with the hydroxyl ion to form water which is basically the neutralization reaction. This cation now reacts with the rest of the fatty acid to form a bipolar molecule which is the soap. During the reaction, the solution becomes cloudy but with time, it again goes back to solution. The cloudyness appears because oil isn't soluble in water based solutions and the base is actually made solution in water.
Here the sodium hydroxide reacts with oil to form water and the soap molecule which is a chemical change.
