<h2>option d. is the answer.</h2>
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>
Answer:
c) he describes specific locaions for the electrons
Explanation:
he determined that electron are around the nucleus in fixed orbits where as Rutherford did not give any concept of orbits. the concept of orbits also explains the change in energy levels as the electron moves from higher to lower or lower to higher energy level.
Answer:
17 ppm
Explanation:
Paso 1: Información brindada
Masa de soluto: 0.025 g
Volumen de solución: 1.5 L
Paso 2: Convertir la masa de soluto a miligramos
Usaremos el factor de conversión 1 g = 10³ mg.
0.025 g × (10³ mg/1 g) = 25 mg
Paso 3: Calcular las partes por millon (ppm) del soluto
Usaremos la siguiente expresión.
ppm = mg de soluto / litros de solución
ppm = 25 mg / 1.5 L
ppm = 17 mg/L
Answer:
The new pressure of the gas comes out to be 400 KPa.
Explanation:
Initial volume of gas = V =
Initial pressure of gas = P = 120 KPa
Final volume of gas = V' =
Assuming temperature to be kept constant.
Assuming final pressure of the gas to be P' KPa
New pressure of gas = 400 KPa
