A student has a balloon with a volume of 2.5 liters that contains 4.0 moles of air. The ballon has a small leak, allowing one mo

le to escape, leaving just 3.0 moles of air inside the balloon. What is the balloon's new volume after the air has escaped?

Answer:

1.9 L

Explanation:

Step 1: Given data

  • Initial number of moles of air (n₁): 4.0 mol
  • Initial volume of the balloon (V₁): 2.5 L
  • Final number of moles of air (n₂): 3.0 mol
  • Final volume of the balloon (V₂): ?

Step 2: Calculate the final volume of the balloon

According to Avogadro's law, the volume of an ideal gas is directly proportional to the number of moles. We can calculate the final volume of the balloon using the following expression.

V₁ / n₁ = V₂ / n₂

V₂ = V₁ × n₂ / n₁

V₂ = 2.5 L × 3.0 mol / 4.0 mol

V₂ = 1.9 L

A complex ion that forms in solution has a structure that:____.
xeze [42]

Answer:

can only be determined experimentally.

Explanation:

In the early days of inorganic chemistry, the structure of complex ions remained a mystery hence the name ''complex''.

These ions appear to have structures that defied accurate elucidation. However, by diligent laboratory investigation, Alfred Werner was able to accurately determine the structure of cobalt complexes. As a result of this, he is regarded as a pathfinder in coordination chemistry.

Hence, the structure of complex ions can only be determined experimentally.

Law Incorporation [45]

Answer:

wave speed

Explanation:

A wave is a disturbance that transmits energy from one place to another without the actual displacement of the particles of the medium.

To find the wave speed we need to determine the product of its frequency and wavelength.

  Wave speed  = Frequency x wavelength

Frequency of wave is the number of wave that passes through a point at a unit time.

Wavelength is the displacement of a complete wave train.
