Answer:
A particle
Explanation:
Modern quantum theory holds that light has both wave-like and particle-like properties. When the length scales involved are large compared to the wavelengths of light (ex., forming images with thin lenses), the
particle nature of light dominates.
Answer:
0.1935atm is the pressure of the gas.
Explanation:
In the problem you have the mass of Neon (You can obtain moles using molar mass), you have volume, and temperature. You can use general ideal gas law to solve pressure:
PV = nRT
P = nRT / V
<em>Where P is pressure in atm, n are moles, R is gas constant (0.082atmL/molK), T is absolute temperature (20.0°C + 273.15 = 293.15K), and V is volume in L = Volume in dm³</em>
<em />
<em>Moles gas:</em>
Molar mass Ne = 20.1797g/mol
0.325g * (1mol / 20.1797g) = 0.0161 moles
Replacing:
P = nRT / V
P = 0.0161 moles * 0.082atmL/molK * 293.15K / 2L
P = 0.1935atm is the pressure of the gas
Answer:
An emerald can be described as a pure substance because it is a compound. it's a pure substance because it is an element. It's an impure substance because it is chemically combined, an impure substance because it is a mixture.
