Assume that a hydrogen atom's electron has been excited to the n ???? 5 level. how many different wavelengths of light can be em
hichkok12 [17]

n = 5 --> n = 4

n = 4 --> n = 3

n = 3 --> n = 2

n = 2 --> n = 1

<span>So we can see that there are 4 different wavelength of light that can be emitted</span>

A rigid container of O 2 has a pressure of 340 kPa at a temperature of 713 K. What is the pressure at 273°C ?
Vinvika [58]

Answer:

260 kPa

Explanation:

To answer this problem we can use <em>Gay-Lussac's law</em>, which states that at a constant volume (such as is the case with a rigid container):

  • P₁T₂=P₂T₁

Where in this case:

  • P₁ = 340 kPa
  • T₂ = 273 °C ⇒ 273 + 273.16 = 546 K
  • P₂ = ?
  • T₁ = 713 K

We <u>input the data</u>:

  • 340 kPa * 546 K = P₂ * 713 K

And <u>solve for P₂</u>:

  • P₂ =  260 kPa
