Within the visible range of light, red<span> light waves are scattered the least by atmospheric gas molecules. So at sunrise and </span>sunset, when the sunlight travels a long path through the atmosphere to reach our eyes, the blue light has been mostly removed, leaving mostly red<span> and yellow light remaining.</span>
The Beer-Lambert law states that A = E*c*l where A is absorbance, E is the molar absorbance coeffecient, c is concentration and l is path length. Therefore the absorbance is directly proportional to concentration, and by increasing the concentration by a factor of 3, absorbance will increase by a factor of 3 giving A = 1.584
Answer:
<u><em>METALS</em></u>
Lose their valence electrons easily/ ionic by electron loss.
<u><em>NOMETAL</em></u>
Gain or share valence electrons easily/ ionic by electron grain.
Every 4 days, the amount of radon you started with is reduced by half.
Start with 4 grams of radon on day 1
After 4 days, you have (1/2)* 4 grams of radon = 2 grams
Start with 2 grams of radon on day 5
After four more days (end of day 8) you have:
(1/2)*2 grams = ?
Answer:
metaltoids like mercury can become solid and liquid and are called semiconductors
