(2) 2.0 L of Kr (4) 1.5 L of Ar
Answers
Answer: (1) 1.0 L of Ne
Explanation: According to Avogadro's law, 1 mole of every gas occupy 22.4 Liters at STP and contains avogadro's number of particles.
Avogadro's Law: This law states that volume is directly proportional to the number of moles of the gas at constant pressure and temperature.
(At constant temperature and pressure)
Thus equal volumes contain equal number of atoms.
Hence, 1.0 liter of helium contains the same total number of atoms as
1.0 L of Ne at STP.

The percussion instruments are a drum, which makes sound when a mallet hits its surface and a cymbal, which makes sound when it is crashed against another cymbal.
What are percussion instruments?
Percussion instruments generate sound when struck by an object. Among the options provided, the drum and the cymbal are indeed percussion instruments. A drum produces sound when a mallet or stick hits its surface, causing vibrations that create the characteristic drumming sound. Similarly, a cymbal produces sound when it is crashed against another cymbal or struck with a mallet.
So, the percussion instruments that fit the description of making sound when struck are the drum and the cymbal. These instruments belong to the percussion family, which is characterized by its reliance on impact to produce musical tones.
