<h2>Answer:</h2>

<u>A. The photons emitted when an electron drops down an energy level. </u>

<h2>Explanation:</h2>

When a source emits electromagnetic radiation then the spectrum is called as emission spectrum. It is emitted during the process when an atom makes its transition of energy levels to ground state.

Ground state is the state where atom possesses the lowest energy. When an atom or molecule comes down from higher energy level to lower energy level, it emits the spectrum which is called as emission spectrum.

What is potiential and kinetic engergy? pls someone answer my question
Afina-wow [57]

Answer:

Potential Energy is stored energy or energy of position (gravitational). The object isn't moving. For example, a ball being held is potential energy because the object isn't moving but it has the potential of turning into kinetic energy.

Kinetic Energy is the energy of motion. For example, running. You are moving, and there is clear action and activity

A 16.0 g sample of methane gas, CH4, the gas used in a chemistry lab, has a volume of 5.0 L at 27ºC. Calculate the pressure.
NeX [460]

Answer:

4.9 atm

Explanation:

convert 16.0g of CH4 to moles

16.0 g CH4 x 1 mol CH4/16.0 g CH4 = 1.00 mol of methane

convert the temp into Kelvins: 27 + 273 = 300.K

PV = nRT

(P) (5.0 L) = (1.00 mol) (0.0821 L atm/mol K) (300.K)

P = 4.9 atm
