Answer:

c.a cello playing music at a concert

Explanation:

Vibration motion is produced when the strings of a cello are plucked by a musician. Vibration in a string produces a wave, and the vibrating string produces a sound of a certain frequency. Most often we see the tension of a string gets adjusted, and thus help to create a sound or music of a definite frequency.

40.0L of N₂ gas are in a sealed container at STP.How many moles of N₂ are present?9 mol
Vinvika [58]

Explanation:

We have to find the number of moles of N₂ that are present in a sample that has a volume of 40.0 L at STP.

STP means Standard Conditions of Temperature and Pressure. These conditions are 273.15 K and 1 atm. We know that 1 mol of N₂ will occupy 22.4 L. We can use that ratio to find the answer to our problem.

1 mol of N₂ = 22.4 L

moles of N₂ = 40.0 L * 1 mol/(22.4 L)

moles of N₂ = 1.79 mol

Answer: 1.79 moles of nitrogen are present.
