Answer:
C. Two isotopes of hydrogen fuse to form helium.
Explanation:
the mass is converted to energy in nuclear reactions so answer is C. Two isotopes of hydrogen fuse to form helium.
Answer:
231 moles
Explanation:
From the question, Given:
P = 17.7atm , V = 422litres , T = 393K , n = ? , R = 0.0821 atm L/mol K
We can rewrite the ideal gas equation making n the subject.
This is obtained as follows:
From PV = nRT, n = PV/RT
n = (17.7 × 422) ÷ ( 0.0821 × 393)
n = 231 moles

Yes, aluminum conduct electricity.
<u>Answer:</u> The light is getting absorbed for the given transition.
<u>Explanation:</u>
There are two ways in which electrons can transition between energy levels:
- <u>Absorption spectra:</u> This type of spectra is seen when an electron jumps from lower energy level to higher energy level. In this process, energy is absorbed.
- <u>Emission spectra:</u> This type of spectra is seen when an electron jumps from higher energy level to lower energy level. In this process, energy is released in the form of photons.
We are given:
Lower (Initial) energy level = 3
Higher (Final) energy level = 7
As, the electron is jumping from lower energy level to higher energy level. So, the light gets absorbed.
Hence, the light is getting absorbed for the given transition.
