If a 22.4 L volume of a sample of gas has a density of 0.900 grams/L at 1.00 atm and 0.00°C. Given
disa [49]

Answer:

Formula Weight of gas sample = 20.1 g/mole => Neon (Ne)

Explanation:

Use Ideal Gas Law formula to determine formula weight and compare to formula weights of answer choices.

PV = nRT = (mass/fwt)RT => fwt = (mass/Volume)RT = Density x R x T

Density = 0.900 grams/L

R = 0.08206 L·atm/mole·K

T = 0.00°C = 273Kfwt = (0.900g/L)(0.08206L·atm/mole·K )(273K)

= 20.1 g/mol => Neon (Ne)

How can the amount of electrical energy produced be less than the initial radiant energy from the sun?
VLD [36.1K]

It might directly convert into a photoelectric effect like a solar panel. Alternatively, it may be transformed first into mechanical energy, as in boiling a working fluid and powering a turbine, or it could be transformed into chemical energy, as in photosynthesis, which grows trees and then burns the wood to power a steam engine and generator.

<h3> Photoelectric effect:-</h3>

Electrons are released when a material is exposed to electromagnetic radiation, such as light, known as the photoelectric effect. These electrons are referred to as photoelectrons. To derive conclusions regarding the properties of atoms, molecules, and solids, the phenomena are researched in condensed matter physics, solid state chemistry, and quantum chemistry. Electronic devices designed for light sensing and precisely timed electron emission have found usage for the effect.
